Update: The blog Food, Sake, Tokyo has the numbers for this year’s auction. Perhaps most interesting, per kilogram the first tuna of the year wasn’t the most expensive fish. A 168-kg fish sold for $382 per kilo (~$64,000 total) compared to $305 per kg for the first fish of the year. In an unexpected turn, … Read More “First Bluefin Tuna sells for $70,000 at Tsukiji Fish Auction (UPDATED)” »

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.

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

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:

Help Support Ocean Conservation this Holiday Season and Promote your Ocean Conservation Organization!

December 4, 2013December 16, 2013 Andrew Thaler 2 Comments

Conservation

With Thanksgiving in the rearview mirror, we have entered the season for charitable giving. In America alone, there are thousands of ocean conservation organization that rely on donations and grants for their continued operation. Rather than list out our favorites, which tend to get quite a bit of promotion through Southern Fried Science’s various platforms, this year, I am inviting representatives from any ocean conservation organization to promote themselves in the comment thread. So, if your NGO is doing an end of the year fund raiser, if you have an “adopt-a-critter” programs going for the holidays, or if you just want to get the word out about your organization, feel free to leave a comment and let us know a bit about you organization and its goals.

Southern Fried Science has a large, dedicated, and ocean literate audience. Let us know what you’re up to. I promise it will be worth your time.

Check out Musingo, the music trivia app that helps save the ocean

Conservation

This week saw the launch of Musingo, an interactive music trivia app for iOS. The developer, Good World Games, lets users make an impact in the real world through the game apps they play, and Musingo is no different.

Though the app is free, there are opportunities for in-game purchases of additional game tokens, as well as the opportunity to buy the songs you hear through iTunes. 50% of the profits from those in-game purchases are donated to my lab, the RJ Dunlap Marine Conservation Program, where they will be used to help support our many ongoing research projects.

What does the new species of hammerhead mean for shark science and conservation?

November 11, 2013 David Shiffman 3 Comments

Conservation, Science

In the year 2000, Dr. William Driggers, now of the National Marine Fisheries Service’s Southeast Fisheries Science Center in Mississippi, was sampling for sharks in South Carolina. Dr Driggers recalls that “at the time I was collecting samples from various species of sharks for life history studies and also collecting tissues for Dr. [Joseph] Quattro’s genetics work.” Dr. Quattro, a professor at the Marine Science Program and Department of Biological Sciences at the University of South Carolina, had been working on a project to characterize the population genetics of fish in South Carolina by “working my way down river systems to the coast,” he told me. “Even sturgeons were showing population differentiation, so I thought the next animal would be marine, but estuarine dependent – sharks.” Analysis of the samples Dr. Driggers collected led to a surprising result.

“I was asked “what are the chances that I would misidentify a ‘scalloped hammerhead’ and answered that there was no chance as they are very morphologically distinctive (looks like I was wrong),” Dr. Driggers told me. “I was then informed that genetic sequences indicated that some of the specimens I had labeled as ‘scalloped hammerhead’ were distinctly different from known S. lewini sequences. At Dr. Quattro’s request, I began bringing back whole specimens so they could be archived and morphometric analyses conducted. The first whole specimen that was vouchered and shown to be the new species was collected in Bulls Bay in July of 2001.”

In 2006, Dr. Quattro and his team published a paper entitled “Genetic evidence of cryptic speciation within hammerhead sharks,” showing that there may be a previously-unknown species hiding within scalloped hammerheads. When genetic samples of scalloped hammerheads, great hammerheads, and bonnethead sharks were phylogenetically mapped, the team found an unexpected result. Dr. Quattro, told me that “while doing the population genetics of this animals, we found two divergent genetic lineages within what were morphologically scalloped hammerheads. We gathered sequences and specimens from other known species and didn’t find a match – that’s what got us on the whole cryptic species [defined by Bickford et al. 2007 as “two or more distinct species erroneously classified and hidden under one species name”] thing.”

Happy Fun Science Friday – Blinky, the 3-Eyed Crab

Happy FSF everyone, this week we bring you Blinky! For the Simpsons aficionados amongst you, we are unfortunately not referring to the affable 3-Eyed fish, indicative of the radioactive influence of Springfield’s nuclear power plant.

No Blinky is a real-life, 3-eyed crab, discovered and documented by German researcher Gerhard Scholtz and colleagues while working in New Zealand’s Hoteo River. Scholtz and co stumbled upon this 3-eyed organism, and must have wonder during their cursory inspection if they had discovered a new species, one that was defying the principles of bilateral animals. However, upon closer anatomical inspection Scholtz realized that the mystery crab was not a 3-eyed wonder species, but conjoined twins of the already identified Amarinus lacustris crab species.

What can the funniest shark memes on the internetz teach us about ocean science and conservation?

Conservation, Science

In recent years, some of my favorite ocean predators have started to show up in memes. As part of our tradition of using internet humor to educate our readers, I’ve selected the funniest shark memes on the internetz, and I’ve tried to explain what’s going on in the photos used for those memes. I’m happy to discuss these science and conservation issues in the comments if you have any questions, but my selection of what constitutes that funniest shark memes is obviously correct and beyond dispute.

12) Ferocious planktivore is ferocious

What’s going on? This shows a basking shark, the second largest shark in the world, with its mouth open wide. While this gaping maw may appear to be menacing, like whale sharks, the basking shark is a strict planktivore.
