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> <figure></figure> <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>

Cruise workers reveal "hook-up culture" on ships

<p><span>Working within the enclosed environment of cruise ships has encouraged a hook-up culture that matches or even exceeds that of a college dorm, <a href="https://www.businessinsider.com.au/cruise-ship-workers-describe-intense-hookup-culture-2019-2"><em>Business Insider</em></a> reported.</span></p> <p><span>Current and former cruise ship crews revealed to the website that living with their co-workers has brought about a permissive sexual culture in their workplace, with an unusual amount of intimate activity.</span></p> <p><span>"There's a lot of sex on cruise ships," said a former casino manager for a cruise line.</span></p> <p><span>According to former cruise line waiter Brian David Bruns, the hook-up culture is so strong that a co-worker was surprised when he had not hooked up with any colleagues during his first night onboard. "What the hell, man?" Bruns recalled the co-worker saying.</span></p> <p><span>The permissive culture has also led to inappropriate behaviour at times. A former staffer said one of her managers often made comments on her sexual orientation and criticised her hairstyle, while a current employee said male co-workers made advances on her as her boyfriend’s contract was close to ending.</span></p> <p><span>While living on a cruise ship might put sexual activities on fast track, many employees found it as a hindrance in building serious relationships. Taylor Sokol, a former cruise director, said working and living in such a proximity might make it difficult to maintain a healthy distance from romantic partners. "It's kind of hard to give someone their space when you live maybe 10 feet away from them."</span></p> <p><span>Working on the seas also makes settling down a lot more difficult, as a lot of contracts require crews to stay onboard for months. Nina Beader, who used to work for one of the major cruise companies, said she decided to stop working on cruise ships because she wanted to build a family and have time to spend with her children. "I did not want to end up being 40 and not having a family," she said.</span></p> <p><span>Some even resorted to leading double lives. "You get a lot of married people that have their own separate lives on the cruise ship," a former worker told <a href="http://mentalfloss.com/article/70240/14-behind-scenes-secrets-cruise-ship-workers"><em>MentalFloss</em></a>. "I've worked with couples that have wives at home and a whole different relationship while they’re on the cruise ship. It’s kind of like a don’t-ask-don’t-tell policy."</span></p> <p><span>Former cruise singer Ruthie Darling experienced the other end of the story. "After dating an officer for about three months and practically living in his cabin with him, I discovered he had a fiancee on land," she wrote on <a href="https://www.thrillist.com/travel/nation/working-on-a-cruise-ship-tips"><em>Thrillist</em></a>. </span></p> <p><span>"A more experienced friend told me that this sort of behaviour wasn't unusual. You had your relationship at sea and your relationship on land. The more I looked around at career cruisers, the more I noticed it was standard practice."</span></p>

How Facebook keeps users hooked

<p>Cocaine, heroin, slot machines - talk to an expert about the workings of Facebook and it's not long before the addiction analogies begin to crop up.</p> <p>Most Facebook users have at some point logged into Facebook for a specific reason, and 10 minutes later found themselves lost in the abyss of their feed.</p> <p>You do it by accident, but it's no accident at Facebook's end, says Seth Zorn, creative director at digital marketing agency Tailgunner Web &amp; Communications, who has also worked in public relations for a number of addiction and health services.</p> <p>"Facebook does nothing on a whim, everything is calculated with the aim to keep you interacting, to keep you addicted," Zorn says.</p> <p>After all, without our posting, sharing, 'liking' and commenting, the website would die.</p> <p>While we may not realise it, from the moment we log in, Facebook has utilised aspects of behavioral psychology and neuroscience to make sure we ​check our notifications, scroll through our newsfeeds, or post that great new photo.</p> <p><strong>What’s not to like?</strong></p> <p>Arguably, the lifeline of social media is our tendency to become hooked on things that make us feel good.</p> <p>When we receive a like, a tag or a mention, dopamine, the chemical associated with pleasurable feelings, is released into the brain.</p> <p>It is similar to the brain pathways that are stimulated from delicious food, making money, sex, or taking a shot of heroin, Zorn says.</p> <p>It is also one of the reasons you might find that little red number on your notifications icon so difficult to ignore.</p> <p>Facebook also plays on our inherent need for social acceptance. Allowing us to easily "like" and comment on "friends'" activity, Facebook has made maintaining friendships easier than ever before.</p> <p>Even if they are, as Zorn says, "like friendships on life support, being topped-up".</p> <p>When you "like" that photo of an old school friend's puppy, it sufficiently maintains your association with that person, even if you are not close enough to want to comment, or visit.</p> <p>But that interaction also provides Facebook with a valuable exchange of information, and in the world of social media, information means money.</p> <p><strong>You’re working for Facebook</strong></p> <p>Victoria University media studies lecturer Kathleen Kuehn includes Facebook in the realm of "sticky technology", sites which find ways of becoming ingrained into everyday life, and make it hard for you to quit. She herself would love to quit Facebook, but like many academics or company owners, it's become too ingrained in her professional life.</p> <p>"They craft user experience to make you deeply invested in it," Kuehn says. "They're really good at being a convergent platform.</p> <p>"You can use Facebook to log into other things, your contact list on your phone can be integrated, events and birthdays go into your calendar, and if you deleted Facebook, that would all go away."</p> <p>Kuehn is currently researching the new ways in which Facebook ropes in users to do its work, saying, "They just offer the template, we do everything else".</p> <p>"When you check into a place or restaurant, if it hasn't been checked into very much or reviewed, they'll ask you a series of questions about it like if it's good for dancing, how the wi-fi is, or if you want to add hours of operation. So you actually do the work for Facebook.</p> <p>"You can see how the functions evolve over time too. It seems like every time interest starts to slip they roll out some new feature like the 'memories', or the way they've employed facial recognition technology that suggests tagging your friends, all sorts of things to kind of trap you in and keep you productive and engaging on the site."</p> <p><strong>It’s social glue but don’t sniff it</strong></p> <p>One of the things that keeps us coming back is Facebook's seamlessness, fellow Victoria University School of design lecturer Walter Langelaar says. "Facebook is very good at presenting its users with interface functionality that is very seamless and well designed."</p> <p>Is that a bad thing? "I don't necessarily see it all as very sinister, or a game Facebook is playing to try and get revenue, I definitely see the benefits, and the social glue that Facebook provides.</p> <p>"I do believe that now people are very connected to each other in different, quick, and efficient ways, and there are a lot of benefits to it. I just think it's a bit crappy that it's run by companies," he says.</p> <p>"While they are supposedly providing you with a service, it's actually you who is working for them, not the other way around. That's why it's important for them to employ these tactics."</p> <p>One thing to remember, says Langelaar, is that if you can use a product for free, then most likely, you are the product.</p> <p>He's never had an account himself. "They still call it 'social networking', but in various other ways you could also call it 'anti-social networking'," he says.</p> <p>What are your thoughts?</p> <p><em>Written by Hannah McKee.

14 clever ways to use adhesive hooks in the home

<p>You knew they were handy but did you know just how handy adhesive hooks (and strips) are? These 14 clever ideas will help you organise and tidy almost everything in your home.</p> <p><strong>1. Conceal cords</strong></p> <p>With many of us having a few technological gadgets at home, those power cords can become a bit of an eyesore, not to mention the potential tangles. Tiny adhesive hooks can help keep your cords tidy and camouflaged.</p> <p><img width="353" height="500" src="https://oversixtydev.blob.core.windows.net/media/10740/1.jpg" alt="1 (106)"/></p> <p><strong>2. Keep chair cushions from moving</strong></p> <p>If your chairs don’t have ties on them, stop them from shifting around with adhesive strips. Plus, it means you can still remove them to clean the chairs and cushions.</p> <p><img width="500" height="375" src="https://oversixtydev.blob.core.windows.net/media/10741/2_500x375.jpg" alt="2 (111)"/></p> <p><strong>3. Hang shower supplies</strong></p> <p>If your shower caddy keeps slipping off the showerhead’s neck, hang it on an adhesive hook. Make sure it’s a sturdy one that can stand the wet conditions.</p> <p><img width="480" height="493" src="https://oversixtydev.blob.core.windows.net/media/10743/3.jpg" alt="3 (107)"/></p> <p><strong>4. Store pot lids</strong></p> <p>Pot lids are notoriously difficult to store so this just may be the solution you need. Make a lid holder out of two hooks on the back of cupboard doors.</p> <p><img width="500" height="375" src="https://oversixtydev.blob.core.windows.net/media/10744/4_500x375.jpg" alt="4 (100)"/></p> <p><strong>5. Hang plastic bags</strong></p> <p>If you like to keep on to your plastic bags after a trip to the supermarket, hang them at the back of a door to keep them neat, tidy and easily accessible.</p> <p><img width="375" height="500" src="https://oversixtydev.blob.core.windows.net/media/10745/5.jpg" alt="5 (93)"/></p> <p><strong>6. Decorate with ease</strong></p> <p>With Christmas coming up soon, this is a nifty trick to know: place a hook upside down on the back of the door to stylishly hang a wreath.</p> <p><img width="320" height="428" src="https://oversixtydev.blob.core.windows.net/media/10746/6.jpg" alt="6 (91)"/></p> <p><strong>7. Hang bulky utensils</strong></p> <p>Those big kitchen utensils can be hung neatly on the back of cupboard doors with some well place adhesive hooks.</p> <p><img width="374" height="398" src="https://oversixtydev.blob.core.windows.net/media/10747/7.jpg" alt="7 (83)"/></p> <p><strong>8. Tidy TV cords</strong></p> <p>The back of the TV is known for its disarray of criss-crossing cables but with a command hook, it will be untidy no more. </p> <p><img width="500" height="333" src="https://oversixtydev.blob.core.windows.net/media/10748/8_500x333.jpg" alt="8 (77)"/></p> <p><strong>9. Display pictures without nails</strong></p> <p>For those who are renting or just don’t want nails in their walls, adhesive hooks or strips are a great option to hang your frames nail-free.</p> <p><img width="498" height="280" src="https://oversixtydev.blob.core.windows.net/media/10749/9_498x280.jpg" alt="9 (63)"/></p> <p><strong>10. Make a bin in your car</strong></p> <p>Hang a bag inside your car for an easily accessible bin to stash rubbish without cluttering up the car.</p> <p><img width="480" height="808" src="https://oversixtydev.blob.core.windows.net/media/10750/10.jpeg" alt="10 (47)"/></p> <p><strong>11. Keep a garbage bag in place</strong></p> <p>Attach a hook on either side of your garbage bin and loop the handles for a garbage bag that never slips out of place.</p> <p><img width="498" height="280" src="https://oversixtydev.blob.core.windows.net/media/10751/11_498x280.jpg" alt="11 (21)"/></p> <p><strong>12. Hang hook-unfriendly items</strong></p> <p>A command hook and a binder clip means you can now hang hook-unfriendly items.</p> <p><img width="498" height="280" src="https://oversixtydev.blob.core.windows.net/media/10752/12_498x280.jpg" alt="12 (16)"/></p> <p><strong>13. Mount toothbrushes</strong></p> <p>Use small hooks turned sideways to store toothbrushes.</p> <p><img width="498" height="280" src="https://oversixtydev.blob.core.windows.net/media/10753/13_498x280.jpg" alt="13 (6)"/></p> <p><strong>14. Create a tablet holder</strong></p> <p>With a few hooks you can create a tablet holder in any room in your house.</p> <p><img width="498" height="280" src="https://oversixtydev.blob.core.windows.net/media/10754/14_498x280.jpg" alt="14 (3)"/></p>
