An open challenge to journalists covering next week’s Bluefin Tuna Auction

December 29, 2013 Andrew Thaler 3 Comments

Conservation

Every year, on the first Saturday of January, crowds gather at the Tsukiji fish market in Tokyo to watch the auction of the first Bluefin Tuna of the year. For the last three years, the legendary first tuna broke the record for most expensive fish ever purchased — $396,000 in 2011, $736,000 in 2012, and a staggering $1,800,000 in 2013. Often highlighted as a symbol of the extent people are willing to go to eat that last bluefin tuna, the annual sale of this fish sets the tone for tuna conservation. With the relocation of the Tsukiji fish market to Toyosu in 2014, next week’s auction promises to be the biggest one yet.

Southern Bluefin Tuna are critically endangered, yet political maneuvering has kept tuna fisheries open and several Pacific nations have been caught falsifying their catch reports. Even still, the massive sale of the first tuna of the year is not indicative of the real demand for Bluefin Tuna.

13 amazing things scientists discovered about sharks in 2013

Conservation, Science

Other than a certain week in August whose name we shall not speak here, 2013 was a great year for both shark science and the communication of that shark science. There were many important and fascinating discoveries, and many of the world’s top media outlets covered them. Presented here is a list of 13 amazing scientific discoveries made in 2013, in no particular ranking order. To make the list, research must have been published in a peer-reviewed scientific journal in 2013, and someone else other than me must have also thought it was awesome (i.e. it received mainstream media or blog coverage). In the interest of objectivity, I did not include any papers that I or my lab were directly involved with. Whenever possible, I’ve linked to an accessible version of the paper.

1) A two-headed bull shark!

Citation: Wagner, CM, Rice, PH, and Pease, AP 2013. First record of dicephalia in a bull shark Carcharhinus leucas foetus from the Gulf of Mexico. Journal of Fish Biology 82: 1419-1422.

Brief description: Researchers presented the first case of a bull shark embryo with 2 heads (the mother was caught by a Florida fishermen). In response to the most common question I received about this study, no, this animal would not have survived to adulthood. While this is a cool discovery, the broader significance is somewhat minimal. As I told science writer Douglas Main in an interview about a similar study, “There have been a number of reports of deformed shark and ray embryos in recent years— two heads, one eye, etc. There’s no evidence to suggest these defects represent a new phenomenon or that they are harmful to shark populations as a whole.”

Media coverage highlights: A figure from this study was named one of the coolest science photos of the year by the International Science Times. It was also covered by National Geographic, the Guardian, and TIME magazine.

More than 100 shark scientists, including me, oppose the cull in Western Australia

Following the tragic fatal bite of surfer Chris Boyd, the government of Western Australia has again proposed a misinformed policy that would harm populations of threatened animals without making surfers or swimmers safer. By targeting any large shark that swims within a specific area, including endangered species and species not considered a safety risk to humans, this policy is essentially a cull. The family of one of the victims of a fatal shark bite opposes the cull, as do scientific experts, local surfers and thousands of concerned environmentalists around the world.

Dr. Ryan Kempster, shark biologist and founder of Support Our Sharks, provided a brief statement on this issue:

There is no denying that each and every shark fatality is a tragedy and our sympathy is, of course, with the family and friends of the victims. However, based on statistical data, the number of shark related fatalities is negligible when you consider the vast and increasing number of swimmers entering our coastal waters every year.

So often the argument in favour of a cull comes down to the emotional question of who is more important: a human or a shark. Rather, we need to ask the question, will culling sharks actually reduce the risk of an attack?

The answer is likely to be no. In fact, when shark culling was carried out in Hawaii, between 1959 and 1976, over 4,500 sharks were killed and yet there was no significant decrease in the number of shark bites recorded. We need to invest in more research to better understand the movement patterns of sharks and learn more about the cues that entice sharks to bite people in the first place so that we can avoid these situations in the future.

Dr. Kempster also drafted an open letter to the government of Western Australia. This letter, which has been co-signed by more than 100 shark scientists from all over the world (including me), is reproduced below. It highlights why a shark cull is ineffective at reducing shark bites and why culls harm threatened species, in addition to proposing alternative suggestions. Additionally, shark biologist Dr. Barbara Wueringer started an online petition, which currently has over 34,000 signatures.

I urge the government of Western Australia to enact the alternative policies proposed by Dr. Kempster and other experts. Culls do nothing to help make people safer, and they can do great harm to populations of threatened (and legally protected) species.

25 signs that you were a conservation child of the 90’s

December 22, 2013December 22, 2013 Andrew Thaler

Conservation, Popular Culture

The 90’s were a big decade for the environmental movement. The media landscape was filled with environmentally-themed programming. Major laws in the US and internationally were passed to protect the planet. Formative events galvanized, diversified, and sometimes radicalized the conservation community. And, like many other of our generation, we came of age right in the middle of it.

Here are 25 signs that your laid the foundation for your environmental ethic squarely in the 1990’s. Happy Holidays from Southern Fried Science.

1. Captain Planet taught us that “The Power is Yours!”

You knew this would be on the list, so let’s get it out of the way. Moving on.

Mythbusting Citizen Science Roundup

December 20, 2013December 20, 2013 Bluegrass Blue Crab 1 Comment

Conservation

Over where I hang my workday hat, recently we’ve thought a lot about the field of citizen science and how it’s developing. Specifically, the push from leaders and scholars in the field to “retake citizen science” by broadening the definition to include the many formulations of decentralized expertise present in our world in the quest for new knowledge.

As part of that ‘re-taking’, I’ve taken on some of the major stereotypes about citizen science and volunteers. I hope to take on more, and would appreciate suggestions, Mythbusters-style, of stereotypes to investigate. But for now, here’s a roundup of the perceptions thus far:

The Invisible Disability: The diabetic academic manifesto

Blogging, Science

Whenever I fill out a job application, there are those little demographic questions at the end and I’m always a bit stymied. They ask if I have a disability that should be taken into account. I don’t, but in the world of academia I feel like I should say yes. I’m diabetic and due to constant fear I keep wearing diabetic socks for men so as to prevent foot complications and my post-PhD it’s starting to become a tangible hindrance for the first time in my life.

Ever the optimist, I tend to dismiss the cases in which the fact that I have a chronic disease directs my decisions. But lately, the cases have piled up to the point I need a cathartic moment to vent. And while a personal subject, I hope my thoughts can be either enlightening or instructive to those thinking about personal health in the ivory tower. Because that’s part of the problem – something held close because it’s personal keeps the issue out of public discourse, which is precisely where solutions might someday emerge.

10 fish weirder than the fish in the 10 weirdest fish in the world list

Second string. Almost famous. Runner up. We’ve all been there—bowed out gracefully and stuffed down the BAMF within. I’m talking the missed, the forgotten, the less-than-top dogs (or in this case, fish). Such was the fate of these ten water-dwellers, left looking up at the podium of last month’s “Top Ten Weirdest Fish in the World” list.

Just keep swimming my finned-friends, I’ve got you covered. They may not be the blobbiest, the toothiest, or the most menacing—but for these creatures, weird comes naturally. In their honor, it’s time for round two: the top ten weirder than the weirdest fish in the world list.

On the clarity of animals: the art and science of clearing and staining

December 17, 2013December 18, 2013 Guest Writer 5 Comments

Dr. Adam Summers is trained as an engineer and mathematician, he turned to biology to satisfy a deep need to interact with nature. His research applies simple physics and engineering principles to animals to understand the evolution of complex behaviors like feeding, movement and reproduction. The images shown here are the raw material that underlies his research. He is a professor at the University of Washington’s Friday Harbor Labs, author of more than 90 papers, and was the scientific consultant on Finding Nemo. He is obsessed with fishes and has recently come to realize that the tools and aims of science, art and poetry are more congruent than he had supposed. All the cleared and stained fishes can be seen at http://www.picturingscience.com (Editor’s note: Adam was also featured in Gizmodo this week)

In my work I apply simple Newtonian physics and a bit of engineering to problems of how animals do those amazing things. The source of questions is the natural world and there is no better skill set in my business than that of the natural historian. A keen eye for what is going on around you, and a willingness to document it, is a powerful engine for generating great questions. Proposing answers to those questions almost always involves understanding the shape of the underlying system. So, the second most important set of tools I have are anatomical. Key insights are found in a deep understanding of the skeletal system and its associated soft tissue. A common tool in my lab is clearing and staining, which results in an entire specimen that has its mineralized tissue stained red and cartilage a deep blue.

We know what the Bloop is and it’s not mermaids

Are we really doing this again? Already?

Yes, Animal Planet apparently just re-aired the pair of fake mermaid documentaries. Judging by the search terms coming in, people still have the same questions: “Is Mermaids: the New Evidence Fake?” – YES; “Is Paul Robertson a real marine biologist – NO; and finally, a question that is actually interesting, “What is the Bloop?”
