Bride and groom slammed for “gift fishing”

<p dir="ltr">A couple has been rinsed online for sending out the “worst wedding invitation ever” that quickly went viral on social media. </p> <p dir="ltr">The bride and groom decided they would tie the knot in a “private ceremony”, but still decided to send out invitations to those who weren’t actually invited to attend. </p> <p dir="ltr">The invitation asked people to “join us in spirit”, while the word “spirit” was spelled incorrectly. </p> <p dir="ltr">The bride claimed that she thought the cards would soften the blow for loved ones who weren't invited, but many online commenters say they have the opposite effect. </p> <p dir="ltr">The couple were quickly slammed as “patronising and rude” with hundreds of infuriated social media users claiming it was “nothing but a present grab”.</p> <p dir="ltr">“Great way to let people know they aren't invited but you'd still like a present,” one person wrote.</p> <p dir="ltr">“Not even a virtual wedding, this is just tacky,” said another. </p> <p dir="ltr">The view was universal, as one person joked, “We're having a wedding, you're not invited.”</p> <p dir="ltr">“If I got this, it would go straight in the trash,” another said, while someone else suggested, “I'd use it as kindling for the fire pit.”</p> <p dir="ltr">Some people also added that despite the couple’s alleged best intentions with the non-invites, they were bound to cause confusion among recipients. </p> <p dir="ltr">“She's going to get so many confused phone calls about this,” one person said.</p> <p dir="ltr">“People will be confused about where to buy tickets,” said another. </p> <p dir="ltr"><em>Image credits: Shutterstock / Facebook</em></p>

"This is crazy": Teenager goes fishing and emerges a millionaire

<p>A 19-year-old fisherman has reeled in a million-dollar barramundi as part of a years long fishing competition. </p> <p>Keegan Payne, a self proclaimed "mad keen" fisherman, caught the fish that had been tagged as part of a nine year long fishing competition in the Katherine River.</p> <p>When the teenager from the Norther Territory was told that he had taken home the prize, he said he planned to use his winnings to help his parents pay off their home loans. </p> <p>"This is crazy for us, we're a big family, there's eight of us. This is more money than we could ever ask for. This is just great," Payne said.</p> <p>"It means so much. This is a once-in-a-lifetime opportunity for me. I'm happy, really happy."</p> <p>"I can buy what I want, maybe help Dad and Mum out with the home loans," he said.</p> <p>Payne was on a fishing trip with family and a friend at the Katherine River when he caught the prized barramundi, and quickly made a call to the hotline for the competition. </p> <p>The organisers confirmed he had caught the million-dollar fish, and invited him and his family to collect the prize. </p> <p>The competition has been running since 2015, but until now, nobody had reeled in one of the million-dollar barramundi.</p> <p>Every season, more than a hundred fish tagged with special markings are released in waterways across the Northern Territory, and while most of the fish are worth $10,000, some are worth the major prize of $1 million.</p> <p>Keegan chose charity partner Cancer Council NT to receive $10,000 from Sportsbet, a sponsor of the competition. </p> <p>NT Major Events Company chief executive Suzana Bishop said organisers were "so happy and excited for Keegan".</p> <p>"We guaranteed a winner this season and we're delighted to see the prize go off," said Sportsbet chief executive Barni Evans.</p> <p><em>Image credits: Million Dollar Fish </em></p>

What is negative gearing and what is it doing to housing affordability?

<p><em><a href="https://theconversation.com/profiles/michelle-cull-340911">Michelle Cull</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a></em></p> <p>Australia’s housing crisis is putting the <a href="https://www.mortgagechoice.com.au/guides/what-is-the-great-australian-dream/">Australian dream</a> to own one’s home out of reach for many.</p> <p>But it’s not just <a href="https://www.aihw.gov.au/reports/australias-welfare/home-ownership-and-housing-tenure">home ownership</a> that has been affected. Rental affordability has also become a serious issue. This has reignited the debate about negative gearing; whether or not it is fair and whether it holds the key to fixing the housing crisis.</p> <h2>What is negative gearing?</h2> <p><a href="https://treasury.gov.au/review/tax-white-paper/negative-gearing">Negative gearing</a> refers to using borrowed money to invest in an asset so it results in a loss which can be claimed as a tax deduction against other income. For example, a property investment is negatively geared if the net rental income received is lower than the mortgage interest. The loss is then offset against other income, such as wages and salaries, which reduces the amount of income tax payable.</p> <p>Negative gearing is commonly used for property investments but also applies to other investments (such as shares). Investments can also be positively geared when net income from the investment is more than the interest on borrowings.</p> <p>The attractiveness of negative gearing in Australia is mainly due to its ability to reduce the amount of income tax. For this reason, it can be more beneficial to individuals who are on higher marginal tax rates. However, capital gains tax must be paid on any gain when the asset is sold.</p> <h2>How does negative gearing work?</h2> <p>Let’s look at a simple example of negative gearing. Say an investment property was rented to tenants at A$500 a week ($26,000 a year), and associated expenses (such as agent fees, rates, mortgage interest, maintenance) were $40,000 for the year. This leaves a shortfall of $14,000.</p> <p>The property owner can deduct the $14,000 from their taxable income to reduce their liability. For example if they received $100,000 from wages, they would pay tax on only $86,000 (saving $4,550 in income tax). Individuals on higher incomes and therefore higher marginal tax rates would receive larger tax deductions (for example, someone earning over $180,001 would pay $6,300 less tax).</p> <p>While negative gearing an investment property can reduce tax while it is being rented, it can also result in a large <a href="https://www.ato.gov.au/individuals-and-families/investments-and-assets/capital-gains-tax/what-is-capital-gains-tax">capital gains tax</a> bill once the property is sold (even though capital gains tax is halved for assets held for more than 12 months).</p> <p>For example, if the cost base for a property purchased ten years ago was $400,000 and it sells for $900,000 today, capital gains tax would be calculated on half of the $500,000 difference. At a marginal rate of 45%, the tax bill would be $112,500.</p> <h2>How widespread is it in Australia?</h2> <p>According to the <a href="https://data.gov.au/data/dataset/taxation-statistics-2020-21">Australian Taxation Office</a>, about 2.25 million individual tax payers (21% of all individual tax payers) claimed deductions against rental income for a total 3.25 million properties in 2020-21 financial year.</p> <p>Of these, 47% negatively geared their properties, claiming a net rental loss. This is equivalent to just less than 10% of all taxpayers. Investors with fewer properties were more likely to be using negative gearing with over 71% of property investors having only one investment property.</p> <hr /> <p><iframe id="Wv9lV" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/Wv9lV/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>The largest group of property investors (524,220) had one investment property and a total annual taxable income between $50,001 and $100,000. The chart above shows the proportion of property investors by age group.</p> <p>From 2016-2017 to 2020-2021, the total net rental income on property investments in Australia went from a loss of $3.3 billion to a gain of $3.1 billion (as you can see from the chart below).</p> <p>For the same period, the proportion of investors negatively gearing their properties dropped from 58% to 47%, as lower interest rates reduced losses.</p> <hr /> <p><iframe id="fXnoe" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/fXnoe/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>Negative gearing is also becoming less attractive with the government’s recent changes to <a href="https://treasury.gov.au/tax-cuts">tax brackets and marginal tax rates</a>. According to a study conducted by <a href="https://www.pexa.com.au/staticly-media/2023/03/Whitepaper-2-Private-renting-in-Australia-a-broken-system_compressed-sm-1679450145.pdf">LongView and PEXA</a>, 60% of property investors would be financially better off if they instead put their money into a superannuation fund.</p> <h2>When was it introduced?</h2> <p>Negative gearing has been allowed under tax laws since 1936. It was thought it would encourage investment in housing and increase supply.</p> <p>However, debate around its impact on housing affordability led the government to partially abolish it in 1985 by not allowing rental property losses to reduce tax on other sources of income.</p> <p>There was a shortage of housing and rents rose during the two years it was abolished. As a result, in 1987, negative gearing was reinstated and capital gains tax legislation was introduced.</p> <h2>Is it used in other countries?</h2> <p>Canada, Germany, Japan and Norway use negative gearing. In Finland, France and the United States, rental losses can offset future rental income only. In the US, <a href="https://www.irs.gov/publications/p936#en_US_2023_publink1000229891">home owners are entitled</a> to claim a tax deduction for mortgage interest on their own home.</p> <p>The use and benefit of negative gearing depends upon all aspects of a country’s tax system. So although it may be attractive in countries with high marginal tax rates, other taxes such as capital gains tax, land tax and stamp duties may reduce its appeal.</p> <h2>Negative gearing’s impact on housing affordability</h2> <p>Many factors affect the cost of housing, including interest rates, inflation, employment, the overall taxation system and population growth, making housing affordability a complex issue.</p> <p><a href="https://www.smh.com.au/politics/federal/nz-kills-tax-loophole-on-property-to-slow-soaring-house-prices-20210323-p57d9s.html">In New Zealand, negative gearing is being phased out</a> due to its impact on housing prices.</p> <p>However, unlike Australia, New Zealand does not have capital gains tax, making negative gearing more popular and more likely to impact housing prices. In addition to phasing out negative gearing, the New Zealand government <a href="https://www.hud.govt.nz/our-work/public-housing-plan/">increased the supply of public housing</a> and <a href="https://www.abc.net.au/news/2023-09-25/nz-auckland-house-supply-experiment-results-in-dramatic-change/102846126">relaxed zoning regulations</a> to provide more affordable housing.</p> <p>In Australia, however, there are concerns abolishing negative gearing will cause rents to rise, as they did in the 1980s. More innovative approaches to housing affordability are needed to ensure ample supply of property for first home buyers and tenants.</p> <p>Some consideration could be given to allowing first home buyers to claim a tax deduction for mortgage interest, increasing capital gains tax, limiting the number or type of investment properties held, capping rent increases, or more infrastructure investment from the government for first home buyers and social housing.</p> <p>One or more of these measures would be a step in the right direction. Negative gearing on its own is not the answer to housing affordability. The whole system needs an overhaul, with a combination of measures needed to adequately address affordability, for now and for future generations.</p> <p>Taking no action will put home ownership out of reach for even more Australians.<!-- Below is The Conversation's page counter tag.

Fishing town inundated by plague of rats

<p>Communities along the Gulf of Carpentaria in Queensland have been inundated by a plague of rats, with the rodents washing up along the shores in the thousands. </p> <p>Locals and tourists have shared videos of rats washing up on the beaches of Karumba, a popular fishing town that is struggling with the "plague".</p> <p>One local resident took to Facebook to share their experience, writing, “We headed down for our nightly fishing expedition to find the beach littered with washed-up rats.”</p> <p>“We are unable to fish off the beaches at the moment due to the number of them and the smell.”</p> <p>The same local described dead rats floating in the water or washing up on the shore, with those animals that survived looking a little worse for wear. </p> <p>Kerry D Fishing Charters owner Jemma Probert told <a href="https://7news.com.au/news/qld/rat-plague-hits-fishing-town-in-queenslands-north-rocking-confidence-in-vital-tourism-industry-c-12652482" target="_blank" rel="noopener"><em>7News</em></a> the smell of the dead and dying rats was “horrible”.</p> <p>“They are jumping into the water and trying to swim but end up drowning and washing back up on the beach leaving a horrible smell,” she said.</p> <p>Experts say that the influx of rats to the state is due to consistent rainfall, and the subsequent increased crop harvests, as the rodents have flocked to the area looking for food.</p> <p>According to the Commonwealth Scientific and Industrial Research Organisation (CSIRO), the rat population has been steadily increasing since 2021, with the plague of mice and rats slowly heading north to more tropical climates. </p> <p>“Mouse populations have reached plague conditions not seen since 2011,” CSIRO researcher Steve Henry said.</p> <p>“This is largely due to favourable climatic conditions which have created optimal conditions for mice to breed.”</p> <p>Locals have also shared their theories on the influx of their rat visitors, with many speculating that ecent bushfires in the area may be causing the mass exodus of rats leaving burning bushland.</p> <p>“This happened back in the ’90s here in Karumba,” one local said. “They came ashore after (we) had fires in the area.”</p> <p>Locals are worried the unwelcome visitors may have a detrimental effect on the local tourism industry.</p> <p>“I have no idea why they are here but I hope they go quickly as this is not nice for tourists,” Probert said.</p> <p>“They have tried to crawl onto our boat while we are fishing with customers on board and we have had to flick them off with a stick.”</p> <p><em>Image credits: Facebook</em></p>

Are fish oil supplements as healthy as we think? And is eating fish better?

<p><em><a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Fish oil, which contains omega-3 fatty acids, is promoted for a number of health benefits – from boosting our heart health, protecting our brain from dementia, and easing the symptoms of rheumatoid arthritis.</p> <p>But what exactly are omega-3 fats and what does the evidence say about their benefits for keeping us healthy?</p> <p>And if they <em>are</em> good for us, does eating fish provide the same benefit as supplements?</p> <h2>What are omega-3 fats?</h2> <p>Omega-3 fatty acids are a type of polyunsaturated fatty acid. They are essential to consume in our diet because we can’t make them in our body.</p> <p>Three main types of omega-3 fats are important in our diet:</p> <ul> <li> <p>alpha-linolenic acid (ALA), which is found in plant foods such as green leafy vegetables, walnuts, flaxseed and chia seeds</p> </li> <li> <p>eicosapentanoic acid (EPA), which is only found in seafood, eggs (higher in free-range rather than cage eggs) and breast milk</p> </li> <li> <p>docosahexaenoic acid (DHA) is also only found in seafood, eggs (again, higher in free-range eggs) and breast milk.</p> </li> </ul> <p>Omega 3s are key to the structure of our cells, and help keep our heart, lungs, blood vessels, and immune system working.</p> <h2>Eating fish vs taking a supplement</h2> <p>The initial studies suggesting omega-3 fats may have health benefits came from <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/j.0954-6820.1976.tb08198.x">observational studies on people eating fish</a>, not from fish oil.</p> <p>So are the “active ingredients” from supplements – the EPA and DHA – absorbed into our body in the same way as fish?</p> <p>An <a href="https://www.sciencedirect.com/science/article/pii/S0002916523281484">intervention study</a> (where one group was given fish and one group fish oil supplements) found the levels of EPA and DHA in your body increase in a similar way when you consume equal amounts of them from either fish or fish oil.</p> <p>But this assumes it is just the omega-3 fats that provide health benefits. There are other <a href="https://www.foodstandards.gov.au/science/monitoringnutrients/afcd/pages/default.aspx">components of fish</a>, such as protein, vitamins A and D, iodine, and selenium that could be wholly or jointly responsible for the health benefits.</p> <p>The health benefits seen may also be partially due to the absence of certain nutrients that would have otherwise been consumed from other types of meat (red meat and processed meat) such as saturated fats and salt.</p> <h2>So what are the benefits of omega 3 fats? And does the source matter?</h2> <p>Let’s consider the evidence for heart disease, arthritis and dementia.</p> <p><strong>Heart disease</strong></p> <p>For cardiovascular disease (heart attacks and stroke), a <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD003177.pub3/full">meta-analysis</a>, which provides the highest quality evidence, has shown fish oil supplementation probably makes little or no difference.</p> <p>Another <a href="https://www.mdpi.com/2072-6643/12/8/2278">meta-analysis</a> found for every 20 grams per day of fish consumed it reduced the risk of coronary heart disease by 4%.</p> <p>The <a href="https://www.heartfoundation.org.au/getmedia/f1d22267-7381-4513-834b-df317bed9a40/Nutrition_Position_Statement_-_DIETARY_FAT_FINAL-4.pdf">National Heart Foundation</a> recommends, based on the scientific evidence, eating fish rich in omega-3 fats for optimal heart health. <a href="https://apjcn.nhri.org.tw/server/APJCN/17/3/385.pdf">Fish vary in their omega-3 levels</a> and generally the fishier they taste the more omega-3 fats they have – such as tuna, salmon, deep sea perch, trevally, mackeral and snook.</p> <p>The foundation says fish oil may be beneficial for people with heart failure or high triglycerides, a type of fat that circulates in the blood that increases the risk of heart disease and stroke. But it doesn’t recommend fish oil for reducing the risk of cardiovascular diseases (heart attack and stroke).</p> <p><strong>Arthritis</strong></p> <p>For rheumatoid arthritis, <a href="https://arthritis-research.biomedcentral.com/articles/10.1186/s13075-022-02781-2">studies</a> have shown fish oil supplements do provide benefits in reducing the severity and the progression of the disease.</p> <p>Eating fish also leads to these improvements, but as the level of EPA and DHA needed is high, often it’s difficult and expensive to consume that amount from fish alone.</p> <p><a href="https://arthritisaustralia.com.au/managing-arthritis/living-with-arthritis/complementary-treatments-and-therapies/fish-oils/">Arthritis Australia</a> recommends, based on the evidence, about 2.7 grams of EPA and DHA a day to reduce joint inflammation. Most supplements contain about 300-400mg of omega-3 fats.</p> <p>So depending on how much EPA and DHA is in each capsule, you may need nine to 14 capsules (or five to seven capsules of fish oil concentrate) a day. This is about 130g-140g of grilled salmon or mackeral, or 350g of canned tuna in brine (almost four small tins).</p> <p><strong>Dementia</strong></p> <p><a href="https://www.sciencedirect.com/science/article/pii/S0952327807001421?via%3Dihub">Epidemiological studies</a> have shown a positive link between an increased DHA intake (from diet) and a lower risk of developing Alzheimer’s disease, a type of dementia.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S0952327807001421?via%3Dihub">Animal studies</a> have shown DHA can alter markers that are used to assess brain function (such as accumulation of amyloid – a protein thought to be linked to dementia, and damage to tau protein, which helps stabilise nerve cells in the brain). But this hasn’t been shown in humans yet.</p> <p>A systematic review of <a href="http://betamedarts.gr/wp-content/uploads/2021/05/31Psychiatriki03_2020.pdf#page=58">multiple studies in people</a> has shown different results for omega-3 fats from supplements.</p> <p>In the two studies that gave omega-3 fats as supplements to people with dementia, there was no improvement. But when given to people with mild cognitive impairment, a condition associated with increased risk of progressing to dementia, there was an improvement.</p> <p>Another <a href="https://pubmed.ncbi.nlm.nih.gov/25446949/">meta-anlayses</a> (a study of studies) showed a higher intake of fish was linked to lower risk of Alzheimers, but this relationship was not observed with total dietary intake of omega-3 fats. This indicates there may be other protective benefits derived from eating fish.</p> <p>In line with the evidence, the <a href="https://www.alzheimers.org.uk/about-dementia/risk-factors-and-prevention/omega-3-and-dementia#:%7E:text=This%20could%20suggest%20that%20taking,its%20own%20may%20not%20be.">Alzheimer’s Society</a> recommends eating fish over taking fish oil supplements.</p> <h2>So what’s the bottom line?</h2> <p>The more people stick to a healthy, plant-based diet with fish and minimal intakes of ultra-processed foods, the better their health will be.</p> <p>At the moment, the evidence suggests fish oil is beneficial for rheumatoid arthritis, particularly if people find it difficult to eat large amounts of fish.</p> <p>For dementia and heart disease, it’s best to try to eat your omega-3 fats from your diet. While plant foods contain ALA, this will not be as efficient as increasing EPA and DHA levels in your body by eating seafood.</p> <p>Like any product that sits on the shop shelves, check the use-by date of the fish oil and make sure you will be able to consume it all by then. The chemical structure of EPA and DHA makes <a href="https://www.sciencedirect.com/science/article/pii/S0924224421005422">it susceptible to degradation</a>, which affects its nutritional value. Store it in cold conditions, preferably in the fridge, away from light.</p> <p>Fish oil can have some annoying side effects, such as fishy burps, but generally there are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3664575/">minimal serious side effects</a>. However, it’s important to discuss taking fish oil with all your treating doctors, particularly if you’re on other medication.<!-- Below is The Conversation's page counter tag.

"It was a pretty nasty bang": Freddie Flintoff airlifted to hospital

<p>Andrew “Freddie” Flintoff is recovering from a "nasty" accident while filming for <em>Top Gear</em>, according to his friend Piers Morgan. </p> <p>The former English cricketer, 45, was airlifted to hospital on Tuesday after receiving medical care at the scene, following a crash at an aerodrome in Surrey. </p> <p>Piers said he had spoken to Freddie's family, and said the TV host is remaining in good spirits. </p> <p>“I’m told it was a pretty serious crash and that Freddie’s going to be OK, but it might be a little bit more serious than first appreciated,” he told <em>talkSPORT</em>.</p> <p>“I’m told he’s going to be OK, which is great news, but I’m also told it was a pretty nasty bang and that he’s had surgery and is recovering now and we’ll have to wait and see."</p> <p>“I’ve been in contact with them privately but I just want to wish him and his family – Rachael, his wife – all the very best and I think we’re all just keeping our fingers crossed that the big man comes through all right.”</p> <p>It is understood that the crash did not happen at high speed, with all health and safety precautions said to have been in place.</p> <p>The health and safety watchdog said it was “aware and making inquiries” after the BBC reported the incident, as was standard procedure.</p> <p>A BBC spokesperson said at the time, “Freddie was injured in an accident at the <em>Top Gear</em> test track this morning, with crew medics attending the scene immediately. He has been taken to hospital for further treatment and we will confirm more details in due course.”</p> <p><em>Image credits: Getty Images</em></p>

740,000km of fishing line and 14 billion hooks: we reveal just how much fishing gear is lost at sea each year

<p>Two per cent of all fishing gear used worldwide ends up polluting the oceans, our <a href="https://doi.org/10.1126/sciadv.abq0135" target="_blank" rel="noopener">new research</a> finds. To put that into perspective, the amount of longline fishing gear littering the ocean each year can circle the Earth more than 18 times.</p> <p>We interviewed 450 fishers from seven of the world’s biggest fishing countries including Peru, Indonesia, Morocco and the United States, to find out just how much gear enters the global ocean. We found at current loss rates, in 65 years there would be enough fishing nets littering the sea to cover the entire planet.</p> <p>This lost fishing equipment, known as ghost gear, can cause heavy social, economic and environmental damage. Hundreds of thousands of animals <a href="https://link.springer.com/article/10.1007/s11160-018-9520-7" target="_blank" rel="noopener">are estimated to die</a> each year from unintentional capture in fishing nets. Derelict nets can continue to fish indiscriminately for decades.</p> <p>Our research findings help highlight where to focus efforts to stem the tide of fishing pollution. It can also help inform fisheries management and policy interventions from local to global scales.</p> <h2>14 billion longline hooks litter the sea each year</h2> <p>The data we collected came directly from fishers themselves. They experience this issue firsthand and are best poised to inform our understanding of fishing gear losses.</p> <p>We surveyed fishers using five major gear types: gillnets, longlines, purse seine nets, trawl nets, and pots and traps.</p> <p>We asked how much fishing gear they used and lost annually, and what gear and vessel characteristics could be making the problem worse. This included vessel and gear size, whether the gear contacts the seafloor, and the total amount of gear used by the vessel.</p> <p>We coupled these surveys with information on global fishing effort data from commercial fisheries.</p> <p>Fishers use different types of nets to catch different types of fish. Our research found the amount of nets littering the ocean each year include:</p> <ul> <li>740,000 kilometres of longline mainlines</li> <li>nearly 3,000 square kilometres of gill nets</li> <li>218 square kilometres of trawl nets</li> <li>75,000 square kilometres of purse seine nets</li> </ul> <p>In addition, fishers lose over 25 million pots and traps and nearly 14 billion longline hooks each year.</p> <p>These estimates cover only commercial fisheries, and don’t include <a href="https://link.springer.com/chapter/10.1007/978-3-319-97758-4_15" target="_blank" rel="noopener">the amount</a> of fishing line and other gear lost by recreational fishers.</p> <p>We also estimate that between 1.7% and 4.6% of all land-based plastic waste travels into the sea. This amount likely exceeds lost fishing gear.</p> <p>However, fishing gear is designed to catch animals and so is generally understood as <a href="https://www.sciencedirect.com/science/article/pii/S0308597X15002985" target="_blank" rel="noopener">the most environmentally damaging</a> type of plastic pollution in research to date.</p> <h2>Harming fishers and marine life</h2> <p>Nearly 700 species of marine life <a href="https://www.sciencedirect.com/science/article/abs/pii/S0025326X14008571?via%3Dihub" target="_blank" rel="noopener">are known to</a> interact with marine debris, many of which are near threatened. Australian and US <a href="https://www.sciencedirect.com/science/article/pii/S0308597X15002985#bib6" target="_blank" rel="noopener">research in 2016</a> found fishing gear poses the biggest entanglement threats to marine fauna such as sea turtles, marine mammals, seabirds and whales.</p> <p>Other marine wildlife including sawfish, dugong, hammerhead sharks and crocodiles are also known to get <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1442-8903.2010.00525.x" target="_blank" rel="noopener">entangled in fishing gear</a>. Other <a href="https://conbio.onlinelibrary.wiley.com/doi/full/10.1111/conl.12781" target="_blank" rel="noopener">key problematic items</a> include balloons and plastic bags.</p> <p>Lost fishing gear is not only an environmental risk, but it also has an economic impact for the fishers themselves. Every metre of lost net or line is a cost to the fisher – not only to replace the gear but also in its potential catch.</p> <p> </p> <p>Additionally, many fisheries have already gone through significant reforms to reduce their environmental impact and improve the sustainability of their operations.</p> <p>Some losses are attributable to how gear is operated. For instance, bottom trawl nets – which can get caught on reefs – are lost more often that nets that don’t make contact with the sea floor.</p> <p>The conditions of the ocean can also make a significant difference. For example, fishers commonly reported that bad weather and overcrowding contributes to gear losses. Conflicts between gears coming into contact can also result in gear losses, such as when towed nets cross drifting longlines or gillnets.</p> <p>Where fish are depleted, fishers must expend more effort, operate in worse conditions or locations, and are more likely to come in contact with others’ gear. All these features increase losses.</p> <h2>What do we do about it?</h2> <p>We actually found lower levels of fishing gear losses in our current study than in <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/faf.12407" target="_blank" rel="noopener">a previous review</a> of the historical literature on the topic. Technological improvements, such as better weather forecasts and improved marking and tracking of fishing gear may be reducing loss rates.</p> <p>Incentives can further reduce losses resulting in ghost gear. This could include buyback programs for end-of-life fishing gear, reduced cost loans for net replacement, and waste receptacles in ports to encourage fishers to return used fishing gear.</p> <p>Technological improvements and management interventions could also make a difference, such as requirements to mark and track gear, as well as regular gear maintenance and repairs.</p> <p>Developing effective fishing management systems can improve food security, leave us with a healthier environment, and create more profitable businesses for the fishers who operate in it.</p> <p><strong>This article originally appeared on <a href="https://theconversation.com/740-000km-of-fishing-line-and-14-billion-hooks-we-reveal-just-how-much-fishing-gear-is-lost-at-sea-each-year-192024" target="_blank" rel="noopener">The Conversation</a>. </strong></p> <p><em>Image: CSIRO</em></p>

3 recipes using tinned fish

<p>Tinned fish has always been the friend of the impecunious, which hasn't done much for its reputation. But it can be luxurious too, as anyone who has been seduced by beautifully packaged French sardines that sell for more than five times' their budget supermarket counterpart will tell you.</p> <p>Whatever your financial situation, I like to think there's a tinned fish that suits everyone. Here are three ways to get you started.</p> <p><strong>1. Mackerel and kumara fishcakes (pictured above)</strong></p> <p>These are not those strange, bouncy fishcakes of dubious origin that often turn up in Thai restaurants. These are superfood fishcakes, with gentle spice, nuggets of oily fish and sweet kumara.</p> <p><strong><span style="text-decoration: underline;">Serves</span>:</strong> 3-4 as a light meal</p> <p><strong><span style="text-decoration: underline;">Ingredients:</span></strong></p> <ul> <li>2 medium kumara, peeled, cut into chunks</li> <li>1 tablespoon olive oil, plus more for frying</li> <li>2 red onions, finely chopped</li> <li>2 cloves garlic, finely chopped</li> <li>1 tablespoon finely grated fresh ginger</li> <li>1½ teaspoons garam masala</li> <li>finely grated zest of 1 lemon</li> <li>½ cup finely chopped fresh parsley</li> <li>2 eggs</li> <li>420g can mackerel or smoked fish, well drained</li> <li>1 cup panko breadcrumbs</li> </ul> <p><strong><span style="text-decoration: underline;">Method:</span></strong></p> <ol> <li>Boil or steam the kumara until just soft, then drain and mash roughly. Tip into a large bowl and set aside.</li> <li>Heat the oil in a large frying pan, then add the onion, garlic and ginger. Cook for 5 minutes, stirring often, then add the garam masala, a pinch of salt and some cracked black pepper. Cook for a minute or two, then add to the kumara, along with the lemon zest, parsley, one of the eggs and the fish. Stir together gently, then shape into palm-sized cakes.</li> <li>Beat the remaining egg in a shallow dish and put the panko crumbs into another shallow dish. Dip the fishcakes into the egg, then into the crumbs, then set aside.</li> <li>Wipe out the frying pan, then set it over medium heat. Pour a couple of tablespoons of oil into the pan, then cook the fishcakes in batches, turning to ensure a crisp crust on all sides. Remove to a plate and keep warm in a low oven until they are all cooked. Serve immediately with salad greens and aioli.</li> </ol> <p><strong>2. Sophie's pasta with tuna, currants and olives</strong></p> <p>This recipe is probably the most lasting souvenir I have of a trip to England in 1999. I gleaned the basic idea from watching a cooking show featuring Sophie Grigson, who sported carrot-coloured hair and earrings made from miniature soup ladles. It's gradually evolved to this version, which makes a great fast dinner for two.</p> <p><strong><span style="text-decoration: underline;">Serves</span>:</strong> 2</p> <p><strong><span style="text-decoration: underline;">Ingredients:</span></strong></p> <ul> <li>1 red onion, finely chopped</li> <li>3 tablespoons red wine vinegar</li> <li>1 x 180g tin of good-quality tuna in olive oil</li> <li>⅔ cup currants</li> <li>⅔ cup roughly chopped toasted almonds (use sunflower seeds as a budget alternative)</li> <li>1 cup kalamata olives, stoned</li> <li>1 cup finely chopped fresh parsley</li> <li>250-300g dried spaghetti</li> </ul> <p><strong><span style="text-decoration: underline;">Method</span>:</strong></p> <ol> <li>Put the onion and red wine vinegar in a small bowl and leave to steep while you get on with organising everything else.</li> <li>Put the water on to boil for the pasta, and add everything except the spaghetti to the onion mixture, including a tablespoon or so of the oil that the tuna came in. Toss together and season with salt and freshly ground black pepper to taste, adding more olive oil if necessary.</li> <li>Cook the spaghetti until it is al dente and drain, then toss it through the sauce.  Divide between two bowls and serve immediately.</li> </ol> <p><strong>3. Creamy salmon and chilli dip</strong></p> <p>If you have smoked-salmon tastes on a tinned-salmon budget, this dip is a godsend. I remember an old friend making something similar for her 21st birthday, daringly served with crostini and celery sticks. In a world of chips 'n' reduced cream dip, this was haute cuisine indeed. It's also good as a sandwich filling or piled on crusty toast for breakfast.</p> <p><strong><span style="text-decoration: underline;">Makes</span>:</strong> About 2 cups</p> <p><strong><span style="text-decoration: underline;">Ingredients</span>:</strong></p> <ul> <li>1 cup cream cheese, softened</li> <li>finely grated zest of 1 lemon, plus some of the juice</li> <li>1-2 teaspoons hot chilli sauce (tabasco, sriracha etc)</li> <li>1 tablespoon finely chopped fresh mint</li> <li>1 cup (about a 200g tin) red salmon</li> </ul> <p><strong><span style="text-decoration: underline;">Method:</span></strong></p> <p>1. Put the cream cheese, lemon zest and chilli sauce in a small bowl and beat with a fork until smooth. Flake the salmon, then gently fold it into the cream cheese mixture with the mint. Add a little lemon juice if it seems a bit stiff. Taste again for seasoning – add some salt and freshly cracked black pepper until the balance is right. Use immediately or cover and store in the fridge for up to 3 days.</p> <p><em>Images: Getty</em></p>

Where is your seafood really from?

<p>Fake foods are invading our supermarkets, as foods we love are substituted or adulterated with lower value or unethical <a href="https://www.emerald.com/insight/content/doi/10.1108/JFC-09-2020-0179/full/html">goods</a>.</p> <p>Food fraud threatens human health but is also bad news for industry and sustainable food <a href="https://www.fao.org/documents/card/en/c/I8791EN/">production</a>.

This makes it more likely that the food you buy is, in fact, the food you truly want to eat.</p> <h2>Illegal fishing and seafood fraud</h2> <p>Wild-caught seafood is vulnerable to illegal, unreported, and unregulated fishing.</p> <p>Illegal, unreported, and unregulated fishing can have a devastating impact on the marine environment because:</p> <ul> <li> <p>it is a major cause of overfishing, constituting an estimated one-fifth of <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/faf.12462">seafood</a></p> </li> <li> <p>it can destroy marine habitats, such coral reefs, through destructive fishing methods such as blast bombing and cyanide fishing</p> </li> <li> <p>it can significantly harm wildlife, such as albatross and turtles, which are caught as <a href="https://www.sciencedirect.com/science/article/pii/S0006320714003140">by-catch</a>.</p> </li> </ul> <p>So how is illegal, unreported, and unregulated fishing connected to seafood fraud?</p> <p>Seafood fraud allows this kind of fishing to flourish as illegal products are laundered through legitimate supply <a href="https://www.fao.org/documents/card/en/c/I8791EN/">chains</a>.</p> <p>A recent <a href="https://www.pnas.org/doi/abs/10.1073/pnas.2003741117">study</a> in the United States found when seafood is mislabelled, it is more likely to be substituted for a product from less healthy fisheries with management policies that are less likely to reduce the environmental impacts of fishing.</p> <p>One <a href="https://usa.oceana.org/wp-content/uploads/sites/4/fraud_gap_report_final_6_6_16.pdf">review</a> of mislabelled seafood in the US found that out of 180 substituted species, 25 were considered threatened, endangered, or critically endangered by the International Union for Conservation of Nature and Natural Resources (IUCN).</p> <p>Illegal fishing and seafood fraud also has a human cost. It can:</p> <ul> <li> <p>adversely affect the livelihoods of law-abiding fishers and seafood <a href="https://www.sciencedirect.com/science/article/pii/B9780128015926000048">businesses</a></p> </li> <li> <p>threaten food security</p> </li> <li> <p>facilitate human rights abuses such as forced labour and <a href="https://link.springer.com/content/pdf/10.1007/978-3-030-32811-5_127-1.pdf">piracy</a></p> </li> <li> <p>increase risk of exposure to pathogens, drugs, and other banned substances in <a href="https://usa.oceana.org/wp-content/uploads/sites/4/fraud_gap_report_final_6_6_16.pdf">seafood</a>.</p> </li> </ul> <h2>The chemical fingerprints in shells and bones</h2> <p>A vast range of marine animals are harvested for food every year, including fish, molluscs, crustaceans, and <a href="https://www.fao.org/documents/card/en/c/ca9229en/">echinoderms</a>.</p> <p>However, traditional food provenance methods are typically designed to identify one species at a time.</p> <p>That might benefit the species and industry in question, but it is expensive and time consuming. As such, current methods are restricted to a relatively small number of species.</p> <p>In our study, we described a broader, universal method to identify provenance and detect fraud.</p> <p>How? We harnessed natural chemical markers imprinted in the shells and bones of marine animals. These markers reflect an animal’s environment and can identify where they are from.</p> <p>We focused on a chemical marker that is similar across many different marine animals. This specific chemical marker, known as “oxygen isotopes”, is determined by ocean composition and temperature rather than an animal’s biology.</p> <p>Exploiting this commonality and how it relates to the local environment, we constructed a global ocean map of oxygen isotopes that helps researchers understand where a marine animal may be from (by matching the oxygen isotope value in shells and bones to the oxygen isotope value in the map).</p> <p>After rigorous testing, we demonstrated this global map (or “isoscape”) can be used to correctly identify the origins of a wide range of marine animals living in different latitudes.</p> <p>For example, we saw up to 90% success in classifying fish, cephalopods, and shellfish between the tropical waters of Southeast Asia and the cooler waters of southern Australia.</p> <h2 class="align-center zoomable" style="text-align: left;">What next?</h2> <p>Oxygen isotopes, as a universal marker, worked well on a range of animals collected from different latitudes and across broad geographic areas.</p> <p>Our next step is to integrate oxygen isotopes with other universal chemical markers to gives clues on longitude and refine our approach.</p> <p>Working out the provenance of seafood is a large and complex challenge. No single approach is a silver bullet for all species, fisheries or industries.</p> <p>But our approach represents a step towards a more inclusive, global system for validating seafood provenance and fighting seafood fraud.</p> <p>Hopefully, this will mean ensure fewer marine species are left behind and more consumer confidence in the products we buy.</p> <p><em>Dr Jasmin Martino, a Postdoctoral Research Fellow at the Australian Nuclear Science and Technology Organisation, contributed to this research and article.</em><!-- Below is The Conversation's page counter tag.

My fishing story: Kaye Sutton Wheeler

<p><em><strong>Over60 community member, Kaye Sutton Wheeler, shares her fishing story.</strong></em></p> <p>I work at a remote Aboriginal school on a North-East Kimberley station that has some of the most spectacular fishing spots imaginable; with barramundi lying in wait to just leap onto your line. Places on the Dunham River (tributary of the Ord) with names given by the locals, such as Pandanus, Wilson's, Drop-off, Reef, Front Gorge, Back Gorge, Gullering.</p> <p>A really memorable day was when I went out with a local family. A mob sitting on mattresses on the back of the tray back, more crammed into the Toyota and me driving between them – about 70 kilometres through the bush on the station, heading for some far off landmark.</p> <p>After driving for about an hour, we pulled up at a sandy riverbank. All the women leapt off and ran to the water's edge, lines arcing into the water, reels looped over wrists. Large bream were caught at a frenetic pace and thrown onto the bank. When they gauged there were enough, all the fish were scooped up into T-shirts and thrown into the back of the Toyota, and on we drove off.</p> <p>A couple of hours later we stopped at a stunning gorge. Everyone go out of the car, dads, mums, teenagers, kids, babies, even grannies. The young men quickly gathered wood and started a fire, and then the blokes and kids claimed their fishing spots. Some women started chopping up potatoes, carrots and onions, while others washed and scaled the bream. All went into a camp oven with curry powder and other spices and left to cook. The babies were sleeping on a blanket in the shade, and then the women each found a fishing spot. No conversation, just fishing, while a myriad of multi-coloured rainbow honeyeaters flitted and twittered in and out of the overhead branches, accompanied by the occasional splash of a fish jumping up to grab an unsuspecting insect and the frantic splashing of the barramundi, bream and catfish as they were hauled in by these expert fisher-folk. Fish curry for lunch, a nana nap under the trees – I finally “get” fishing.</p> <p><em>Image: Getty Images</em></p>

Illegal fishers and wayward sharks are in the sights of new multispectral imaging

<p>The oceans are warming. Reefs are dying. Fish are on the move.</p> <p>As a result, sharks and illegal fishers are scouring Australia’s coast in search of an increasingly elusive catch, and that, says ESpy Ocean founder Ian Dewey, is having an immense impact on everything from regional tourism to ocean ecologies.</p> <p>Illegal fishers, like sharks, are elusive predators. Their survival depends on being fast, silent and unexpected. They’re threatening a $1.6-billion regional Australia industry.</p> <p>Sharks also aren’t behaving the way they used to. They’re turning up in unexpected places, at unexpected times, which can result in tragedy.</p> <p>“Everyone says use drones or dirigibles to spot them,” Dewey says. “But everyone knows that when we’re on the beach in our string bikinis and Speedos, the last thing we want is a drone above us.”</p> <p>With dark fleets of illegal fishing boats turning off their tracking systems to breach international boundaries, time is of the essence in addressing the problem, just as it is with wayward sharks.</p> <p>“Both are increasing problems,” Dewey says. “I only know in terms of the illegal fishing missions that we’ve been involved in, but invariably there are people around protected areas on a daily basis”.</p> <p>Traditional spotter aircraft can’t cope, and using satellites to track vessels isn’t anything new. What is new is multispectral imaging.</p> <p>A regular camera captures an image on just three channels red, green and blue (RGB) –  generating a crisp image of the visible spectrum if the weather is clear.</p> <p>A multispectral image has up to 110 different frequencies, ranging from ultraviolet to microwave.</p> <p>This imaging technology is nothing new. What is new is applying machine learning to identifying what it “sees”.</p> <p>“So it was a matter of working out what we can do through clouds in all kinds of weather, preferably right on dawn,” says Dewey. “I just started going through what frequencies can do what and – if we are looking for a boat – what the hell’s it gonna look like?”</p> <p>It’s a similar story for sharks – what multispectral signatures do different species give, at what depth, under what conditions, at what time?</p> <p>Dewey says the potential to extract such detail from hyperspectral imaging is enormous.</p> <p>It can identify what a boat is made from, what sort of paint has been used (and how old it is), and what equipment is on the deck.</p> <p>“All these things mean that your picture is different to every other boat in the ocean,” he says. “If we see you today, we can see you tomorrow, match those frequencies, and say – we got you!”</p> <p>ESpy demonstrated the potential of the technology for New South Wales Fisheries over the last Easter long weekend. Suitable satellites were identified, access to their hyperspectral cameras was secured, and patrol vessels were stationed in strategic locations waiting for a call to action.</p> <p>“Our system is incredibly fast, which gives us the edge,” Dewey says. “Generally, our system allows boats to be caught red-handed. That makes it so much easier where the courts are concerned.”</p> <p>The shark-spotting challenge is a more recent project. ESpy is in initial discussions with NSW Fisheries and the University of South Australia’s Industrial AI Research Centre to develop techniques to spot the predators first thing in the morning and use established behavioural patterns to predict where they could move during the day.</p> <p>While trespassing trawlers present a major issue, the deadliest offender is often someone much closer to home. One dragnet can strip an ecosystem of everything from algae and small crustaceans to dolphins and turtles, leaving damage that can take years to recover.</p> <p>“Our big problem in Australia is the little guy who throws out a net once or twice,” Dewey says. “He’s generally local, or at least from within 100-or-so kilometres. But he’s got a high risk of being caught, so he just wants to get in and take as much as possible as quickly as possible.”</p> <p><em><strong><img id="cosmos-post-tracker" src="https://syndication.cosmosmagazine.com/?id=195119&amp;title=Illegal+fishers+and+wayward+sharks+are+in+the+sights+of+new+multispectral+imaging" width="1" height="1" />This article originally appeared on <a href="https://cosmosmagazine.com/earth/oceans/espy-oceans-tracking-waters/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Jamie Seidel.</strong></em></p> <p><em>Image: Shutterstock</em></p> <div id="cosmos-link-back"></div>

Netflix and gill: TV for fish

<p>If you are a fish and want to watch TV, this might be the invention for you.</p> <p>Researchers from the University of Queensland have developed an ultraviolet “television” display specially designed for fish. This could help them learn more about how fish and other animals see the world, they suggest in their paper, published in Methods in Ecology and Evolution.</p> <p>“We affectionately call it the ‘UV-TV’, but I doubt that anyone would want one in their home!” says study leader Samuel Powell.</p> <p>Display monitors such as TVs or computer screens have previously been used in animal studies to learn how subjects react to a visual stimulus. But these are suited to human eyes and not all animals see the same wavelengths.</p> <p>“Human TVs generally use three colours – red, green and blue – to create images, but our newly-developed displays have five, including violet and ultraviolet,” says Powell.</p> <p>“Using this display, it’s now possible to show animals simple shapes, or to test their ability to tell colours apart, or their perception of motion by moving dot patterns.”</p> <p>This is a big step forward to learning how fish and other animals react to particular patterns, but you won’t be watching Finding Nemo with your pet goldfish yet – the TV’s not just low res, it comes with a health warning.</p> <p>“You’d have to wear sunglasses and sunscreen while watching it, and the resolution is quite low – 8 by 12 pixels in a 4 by 5 centimetre area – so don’t expect to be watching Netflix in ultraviolet anytime soon,” says Powell.</p> <p>“This very low resolution is enough to show dot patterns to test fish perception in what’s known as an Ishihara test, which would be familiar to anyone who’s been tested for colour blindness.</p> <p>“In this test, humans read a number hidden in a bunch of coloured dots, but as animals can’t read numbers back to us, they’re trained to peck the ‘odd dot’ out of a field of differently coloured dots.”</p> <p>The tiny TV is sufficient to learn how fish react to colour patterns in nature. “There are many colour patterns in nature that are invisible to us because we cannot detect UV,” says fellow researcher Karen Cheney.</p> <p>“Bees use UV patterns on flowers to locate nectar, for example, and fish can recognise individuals using UV facial patterns.”</p> <p>They are using this to study recognition between particular marine life based on scale patterns, to establish who is the boss.</p> <p>“We’ve recently started studying the vision of anemonefish or clownfish – aka, Nemo – which, unlike humans, have UV-sensitive vision.</p> <p>“Our research is already showing that the white stripes on anemonefish also reflect UV, so we think UV colour signals may be used to recognise each other and may be involved in signalling dominance within their social group.</p> <p>“Who knows what other discoveries we can now make about how certain animals behave, interact and think?”</p> <p>This article originally appeared on <a href="https://cosmosmagazine.com/nature/netflix-and-gill-tv-for-fish/">Cosmos Magazine</a>. </p>

Meet the woman who’s been trapping lobsters since before World War II

<p><span style="font-weight: 400;">Virginia Oliver, 101-year-old resident of Rockland, Maine, started trapping lobsters when she was just 8 years old, right before the Great Depression hit, and she’s been going ever since. She’s been a trailblazer her entire life: when she started, few women were trapping lobsters, and now she’s the oldest lobster fisher in the coastal northeastern state best known for its lobsters, and most likely one of the oldest lobster fishers in the world.</span></p> <p><span style="font-weight: 400;">She tends to her traps with her 78-year-old son Max, having learned about the business from her father, a lobster dealer. Lobsters, which used to be considered a cheap food primarily eaten by working class families, fetched 28 cents/pound when she started trapping; now, having become a delicacy, they fetch 15 times that. Perhaps most surprisingly, she isn’t sick of eating lobster yet – she enjoys a lobster dinner of her own roughly once a week. </span></p> <p><span style="font-weight: 400;"><img style="width: 500px; height: 332.79220779220776px;" src="https://oversixtydev.blob.core.windows.net/media/7844167/gettyimages-1234361930.jpg" alt="" data-udi="umb://media/99b6ddc285094a56b437a724f25c8637" /></span></p> <p><span style="font-weight: 400;">Oliver catches lobsters by loading small fish called menhaden, or ‘pogeys’ in lobster-speak, into wire traps, and drives a boat that once belonged to her late husband that bears her name, ‘Virginia’. She said she has no intention of stopping, but she is concerned about the health of Maine’s lobster population, which is subject to heavy fishing pressure.</span></p> <p><span style="font-weight: 400;">Of her decision to continue working, Oliver said, “I’ve done it all my life, so I might as well keep doing it.” Even after a scare where a crab snipped her finger, requiring seven stitches, she never considered retirement. According to family friend Wayne Gray, the doctor admonished her, asking, “Why are you out there lobstering?” with Oliver responding with a simple, “Because I want to.”</span></p> <p><span style="font-weight: 400;">“I like doing it, I like being along the water. And I’m going to keep on doing it just as long as I can.”</span></p> <p><em><span style="font-weight: 400;">Images: Joseph Prezioso/AFP</span></em></p>

How to choose the right fish oil

<p>Omega-3 essential fatty acids are essential for optimum health. They promote a healthy immune response and can help optimise heart, brain, circulatory, metabolic and joint tissue health.</p> <p>Because our bodies cannot produce these nutrients, they must be consumed through diet or supplements. So, unless you’re eating an abundance of fatty fish (at least 2-3 times per week) you may want to consider getting your omega-3s through a quality fish oil supplement. But with so many options on the market, how are we possibly to know which one to choose?</p> <p>Here’s our top 6 tips on how to ensure you’re not wasting your money on ineffective or unethical products, and are also making the right choice for your individual needs.</p> <p><strong>1. Purity</strong></p> <p>Ensure the oil has been purified, and stripped of heavy metals, pesticides, and environmental toxins. Also consider whether the fish has been sourced from clean or polluted waters.</p> <p>All quality manufacturers should employ a technique to ensure the purity levels of the final product meet the fish oil safety and purity standards as established by The European Pharmacopeia Standard. Even better if they are able to offer you a Certificate of Analysis for every batch of oil to prove the product’s purity levels.</p> <p><strong>2. Sustainability</strong></p> <p>All fish oil brands should follow safe fishing practices, in specified locations, to avoid over-fishing and endangering species – unfortunately, not all companies do this. Whatever supplement you are considering, be sure that the way they source the product follows reputable sustainability practices. Check their website to ensure they are “Friend of the Sea” certified, which verifies the sustainability of fish oils.</p> <p><strong>3. Value for Money / Absorption</strong></p> <p>Oils in the natural triglyceride molecular form enables optimal absorption, over the more easily available (and cheaper) synthetic ethyl-ester molecular form, which is determined by the manufacturing process. While most brands are made up of around 60% triglycerides, to ensure that you are receiving the maximum benefits and value of your chosen supplement, choose a brand that guarantees over 90% triglycerides, such as Nordic Naturals.</p> <p><strong>4. Freshness</strong></p> <p>Your fish oil should be easy to take and have a great taste, proving its safety and freshness. For example, if you bite through a fish oil soft-gel, the oil inside should taste light and fresh. (Fishy-tasting oil means that it has gone rancid!)</p> <p>To maintain freshness, manufacturers should use pure nitrogen during all stages of handling to minimise any exposure to oxygen that might degrade the product. Nitrogen ensures that the fish and oil can be protected from the oxidative rancidity that causes an unpleasant fishy smell and taste (and is not good for the body).</p> <p><strong>5. Fish Oil or Arctic Cod Liver Oil?</strong></p> <p>Both are excellent sources of the omega-3s, EPA and DHA, but in different ratios: Arctic cod liver oil (oil from the livers of Arctic Cod) has more DHA than EPA, whereas fish oil (oil from the bodies of fish, such as sardines and anchovies) provides more EPA than DHA. This makes Arctic Cod Liver Oil a good choice when it comes to brain and eye health, whereas fish oil may be a good choice for supporting a healthy heart. Another difference is that Arctic cod liver oil has small amounts of naturally occurring vitamins A and D, providing even greater immune supportive benefits.</p> <p>As with any supplement, it’s a good idea to talk with your health provider first to see if it’s right for you.</p> <p><strong>6. Liquid or Soft-gels?</strong></p> <p>While some people prefer soft-gels, liquids can provide higher levels of EPA and DHA in a smaller dose, making them more cost-effective. If it is a quality brand of fish oil, the oils should always taste pure and fresh.</p> <p><strong>Featured: Nordic Naturals Arctic Cod Liver Oil</strong></p> <p>Nordic Naturals Arctic Cod Liver Oil™ is made from 100% wild Arctic cod. Unlike other “cod liver oils” on the market, no fish body oils or synthetic vitamins or additives are ever used.</p> <p>Nordic Naturals award-winning Arctic Cod Liver Oil™ is made exclusively from wild Arctic cod, and is an ideal choice to support general health and wellbeing. Vertically integrated from catch to finished product, Arctic Cod Liver Oil far surpasses the strict European Pharmacopoeia Standard for fish oil purity and freshness. Simply put it’s some of freshest cod liver oil in the world.</p> <p>Nordic Naturals Arctic Cod Liver oil comes in a variety of delicious flavours for taking right off the spoon or mixing into your favourite food and drink. Unlike the Cod Liver Oil products many of us were told to take in our youth, Nordic Naturals Arctic Cod Liver Oil™ is so fresh that you can’t even tell it’s from fish!</p> <p>Available from all good health stores.

Panicked sea lions almost sink fishing boat

<p><span style="font-weight: 400;">A fishing crew in southern Chile had a surprising catch, after dozens of sea lions tried to board their boat en masse to escape a pack of hunting killer whales.</span></p> <p><span style="font-weight: 400;">Fisherman Antonio Zapata said he had never experienced anything like it in his four decades at sea, despite the fact that encountering hunting orcas was a relatively common experience.</span></p> <p><span style="font-weight: 400;">Though the crew were sympathetic to the plight of the sea lions, they feared the boat would be damaged or sink even lower into the water under the combined weight of the animals and a full haul of sardines.</span></p> <p><span style="font-weight: 400;">“They were trying to climb on board and we had to spread ourselves around the vessel to try to get them off with sticks because the ones that were getting on were making us sink,” he said.</span></p> <p><span style="font-weight: 400;">“It was a dangerous situation because we couldn’t get the sea lions to go away or make the killer whales leave either.”</span></p> <p><span style="font-weight: 400;">Footage captured on a mobile phone showed the water around the boat filled with thrashing sea lions.</span></p> <p><span style="font-weight: 400;">Though the 10-man crew could be heard joking in the video, Mr Zapata said they were also genuinely worried they could end up in the water too.</span></p> <p><iframe width="600" height="338" src="https://rudo.video/vod/bLSQN9/skin/simple/o/MjAyMS8wNi9sb2Jvcy1tYXJpbm9zLTc1MHg0MDAuanBlZw==" frameborder="0" allowfullscreen="" allow="autoplay; fullscreen"></iframe></p> <p><span style="font-weight: 400;">“There were so many sea lions around the hull that we couldn’t move much - every time we did they got caught up in the propellers and I was worried they could break them altogether,” he said.</span></p> <p><span style="font-weight: 400;">The crew attempted to approach a nearby island so the sea lions could take refuge there instead, but the whales blocked them from nearing the shore.</span></p> <p><span style="font-weight: 400;">Once the whales finally drifted away, the sea lions were able to swim for cover as the boat neared the Talcahuano port.</span></p> <p><span style="font-weight: 400;">“Some of the sea lions came with us into port.

Million dollar fish released into Sydney Harbour

<p>A giant kingfish will be released into Sydney Harbour with $1 million on the line for the lucky fisherman who ends up catching it.</p> <p>Harbour of Life festival organisers have announced plans to release a tagged fish into the western side of the harbour, spanning from Barangaroo to Pyrmont.</p> <p>The only way the giant fish can be caught is with a net as it cannot be fitted with a tracker, like the ones used on sharks, because they only reveal a location when he fish surfaces and kingfish stay submerged.</p> <p>The competition, designed by the Western Harbour Alliance, is part of an effort to kick-start Sydney after coronavirus. </p> <p>“The $1 million kingfish is going to cause a lot of excitement among the millions of anglers across NSW and Australia,” Bob Baldwin, chairman of the Australian Fishing Trade Association, told the <a rel="noopener" href="https://www.dailytelegraph.com.au/news/nsw/sydney-harbour-festival-1m-to-angler-who-catches-tagged-kingfish/news-story/7b02117ccdd55048b01a96d537168873" target="_blank">Daily Telegraph</a>.</p> <p>“I can't think of a better place in the world to wet a line and maybe catch a fortune right in the heart of our magnificent city.”</p> <p>Organisers are hopeful that the festival will rival Vivid, which attracts millions of tourists to the harbour every year and generates $172 million.</p> <p>The festival would begin with a 'sculptures in the sea' exhibition, similar to Hong Kong's annual aquatic art festival.</p>

Don’t count your fish before they hatch: experts react to plans to release 2 million fish into the Murray Darling

<p>The New South Wales government <a href="https://www.smh.com.au/politics/nsw/two-million-fish-to-be-released-into-murray-darling-system-20200608-p550gu.html">plans to release</a> two million native fish into rivers of the Murray-Darling Basin, in the largest breeding program of its kind in the state. But as the river system recovers from a string of mass fish deaths, caution is needed.</p> <p>Having suitable <a href="https://www.dpi.nsw.gov.au/fishing/aquaculture/publications/species-freshwater/collecting-finfish-broodstock">breeding fish</a> does not always guarantee millions of healthy offspring for restocking. And even if millions of young fish are released into the wild, increased fish populations in the long term are not assured.</p> <p>For stocking to be successful, fish must be released into <a href="https://www.mdba.gov.au/sites/default/files/pubs/Strategies-to-improve-post-release-survival-of-hatchery-reared-threatened-fish-species_0.pdf">good quality water, with suitable habitat and lots of food</a>. But these conditions have been quite rare in Murray Darling rivers over the past three years.</p> <p>We research the impact of human activity on fish and aquatic systems and have studied many Australian fish restocking programs. So let’s take a closer look at the NSW government’s plans.</p> <p><strong>Success stories</strong></p> <p><a href="https://www.smh.com.au/politics/nsw/two-million-fish-to-be-released-into-murray-darling-system-20200608-p550gu.html">According to</a> the Sydney Morning Herald, the NSW restocking program involves releasing juvenile Murray cod, golden perch and silver perch into the Darling River downstream of Brewarrina, in northwestern NSW.</p> <p>Other areas including the Lachlan, Murrumbidgee, Macquarie and Murray Rivers will reportedly also be restocked. These species and regions were among the hardest hit by recent fish kills.</p> <p>Fish restocking is <a href="https://www.researchgate.net/publication/233194500_Stocking_Trends_A_Quantitative_Review_of_Governmental_Fish_Stocking_in_the_United_States_1931_to_2004">used worldwide</a> to boost species after events such as fish kills, help threatened species recover, and increase populations of recreational fishing species.</p> <p>Since the 1970s in the Murray-Darling river system, <a href="https://www.bnbfishing.com.au/wp-content/uploads/2017/10/Assessment-of-stocking-effectiveness-of-Murray-cod-and-golden-perch.pdf">millions of fish</a> have been bred in <a href="https://www.dpi.nsw.gov.au/about-us/science-and-research/centres/narrandera-fisheries-centre">government</a> and <a href="https://www.murraydarlingfisheries.com.au/">private</a> hatcheries in spring each year. Young fish, called fingerlings, are usually released in the following summer and autumn.</p> <p>There have been success stories. For example, the endangered <a href="https://www.fishfiles.com.au/media/fish-magazine/FISH-Vol-23-2/Back-from-the-brink">trout cod</a> was restocked into the Ovens and Murrumbidgee Rivers between <a href="https://www.researchgate.net/publication/235774467_Reintroduction_success_of_threatened_Australian_trout_cod_Maccullochella_macquariensis_based_on_growth_and_reproduction">1997 and 2006</a>. Prior to the restocking program, the species was locally extinct. It’s now re-established in the Murrumbidgee River and no longer requires stocking to maintain the population.</p> <p>In response to fish kills in 2010, the Edward-Wakool river system <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/aec.12424">was restocked</a> to help fish recover when natural spawning was expected to be low. And the threatened Murray hardyhead is now increasing in numbers thanks <a href="https://www.environment.gov.au/water/wetlands/publications/wetlands-australia/national-wetlands-update-february-2020/murray-hardyhead#:%7E:text=In%20November%202018%2C%20around%20800,fish%20to%20NSW%20river%20systems.">to a successful stocking program</a> in the Lower Darling.</p> <p>After recent fish kills in the Murray Darling, breeding fish known as “broodstock” were <a href="https://www.abc.net.au/radio/programs/worldtoday/mass-fish-rescue-gets-underway-in-darling-river/11492042">rescued from the river</a> and taken to government and private hatcheries. Eventually, it was expected the rescued fish and their offspring would restock the rivers.</p> <p><strong>Words of caution</strong></p> <p>Fish hatchery managers rarely count their fish before they hatch. It’s quite a challenge to ensure adult fish develop viable eggs that are then fertilised at high rates.</p> <p>Once hatched, larvae must be transported to ponds containing the right amount of plankton for food. The larvae must then avoid predatory birds, be kept free from disease, and grow at the right temperatures.</p> <p>When it comes to releasing the fish into the wild, careful decisions must be made about how many fish to release, where and when. Factors such as water temperature, pH and dissolved oxygen levels must be carefully assessed.</p> <p>Introducing hatchery-reared fish into the wild does <a href="https://www.sciencedirect.com/science/article/pii/S0044848610004540?casa_token=NbFwq0hZLSgAAAAA:SntmSZkoWH387KKTDvXn-rHg-I6P0P0Q-OfgI6hvb6gp_Hxy82Y9AMIndcMYR3yarSkeFOY_cWE">not always deliver</a> dramatic improvements in fish numbers.

But stocking programs must also consider the underlying reasons for declining fish populations.</p> <p>Aside from poor water quality, fish in the Murray Darling are threatened by being sucked into irrigation systems, cold water pollution from dams, dams and weirs blocking migration paths and invasive fish species. These factors must be addressed alongside restocking.</p> <p>Fish should not be released into areas with unsuitable habitat or water quality. The Darling River fish kills were caused by <a href="https://www.mdba.gov.au/managing-water/drought-murray-darling-basin/fish-deaths-lower-darling/independent-assessment-fish">low oxygen levels</a>, associated with drought and water extraction. These conditions could rapidly return if we have another hot, dry summer.</p> <p>Stocking rivers with young fish is only one step. They must then grow to adults and successfully breed. So the restocking program must consider the entire fish life cycle, and be coupled with good <a href="https://www.abc.net.au/news/rural/2019-08-28/more-fish-kills-expected-as-nsw-government-announces-rescue-plan/11457826">river management</a>.</p> <p>The Murray Darling Basin Authority’s <a href="https://www.mdba.gov.au/sites/default/files/pubs/Native%20Fish%20Emergency%20Response%20Plan%20-%20October%202019_0.pdf">Native Fish Recovery Strategy</a> includes management actions such as improving fish passage, delivering environmental flows, improving habitat, controlling invasive species and fish harvest restrictions.
