Public passion for shark finning bans is great. How do we channel it towards other issues?

January 9, 2014January 9, 2014 David Shiffman 14 Comments

A recent proposal in New Zealand to outlaw shark finning received more than 45,000 public comments from all over the world, a staggering amount of public interest in fisheries policy. This is great news, because though many activists don’t really know what it means, shark finning is a major threat. Shark finning may well be the most brutal and wasteful method of gathering food in the history of human civilization, and New Zealand was one of the few developed nations that still legally allowed any form of the practice. Though there are still some significant issues with New Zealand’s proposal, it was still very exciting to see so much public passion for an issue that few cared about, or even knew about, when I was growing up.

However, a finning ban is merely a first step, for the most part only controlling how sharks are killed, not how many are killed. A recent study showed that finning bans alone were insufficient to ensure sustainable fisheries. In many nations (including the United States), the interested public has a role to play in implementing all or most of the next steps a comprehensive sustainable fisheries policy for sharks and other fishes. Unfortunately, we haven’t seen anywhere near the same level of public engagement in other shark conservation issues as we see for big, flashy issues like bans on finning.

Are you Prepared for the end of the world? An excerpt from my latest novella

Prepared: A novella from the world of Fleet went live in the Amazon Kindle store this afternoon. This short story expands on the world the we first encountered in Fleet, where sea level rise and global pandemic have reduced human civilization to a few scattered enclaves. In Prepared, we are taken to the beginning of the end, the fall of the last major coast metropolis, where a small group of doomsday preppers are making their final stand.

You can find Prepared on Amazon and at Smashwords. Nook, iBook, and other editions are coming.

Fukushima continues to dominate the ocean news cycle, and while no one is denying that it is a real and ongoing tragedy, the woo is strong in the Fukushima fear-mongering community. Fortunately, the scientists are out in force, debunking the bunk and cutting through the crap to keep you informed. Here is a handy collection of detailed links, from trusted source, tackling some of the most egregious pseudoscience coming out of Fukushima.

First Bluefin Tuna sells for $70,000 at Tsukiji Fish Auction (UPDATED)

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.

Fun Science Friday – BP Oil Spill Impacts Dolphins

Happy Fun Science Friday!

Though this post does not present such a happy story, given the recent discussion about dolphin photobombing, this week’s FSF is topically related. In the spring of 2010 the Deepwater Horizon oil rig experienced catastrophic failure resulting in the worst oil spill in human history. The Gulf of Mexico (GoM) was the unfortunate host of this catastrophe and the GoM community is still feeling the ecological, social, and economic consequences of this disaster.

One such impact that received little TV coverage during the spill was the uncharacteristic spike in dolphin deaths. A few months following the BP spill there was an unprecedented spike in dead dolphins washing ashore along the Gulf Coast; 67 dead dolphins by February of 2011, with more than half (35) of the dead dolphins being calves. This is in stark contrast to years preceding the spill when one or two dead dolphins per year were normally documented to wash ashore. Despite the spike in dolphin deaths, there was no definitive evidence linking the dead cetaceans to the oil spill as a number of other factors could have been responsible for the deaths, including infectious disease or the abnormally cold winter proceeding the spill.

3 sharks that were on twitter before being a shark on twitter was cool

Recent plans in Western Australia to place acoustic tags in sharks and have them tweet their location when they approach a beach have resulted in a sharknado of media coverage. The plan has been covered by internet technology news giant Mashable, Fox News, NPR news, Popular Science, and NBC news (which, with “sharks with frickin’ tweets,” has what I believe to be the best headline. That one also interviews me.) When a tagged shark approaches the beach, a tweet like this results:

I can understand why a project involving both sharks and twitter caught the media’s eye… and why about a billion of you e-mailed or tweeted the news to me. However, these aren’t the first sharks to be on twitter!

She is Deputy Chair of the IUCN Shark Specialist Group and Conservation Committee Chair for the American Elasmobranch Society, has co-authored numerous publications on shark fisheries management, and serves on most of the U.S. federal and state government advisory panels relevant to sharks and rays. Her awards include the U.S. Department of Commerce Environmental Hero Award, the Peter Benchley Shark Conservation Award, and the IUCN Harry Messel Award for Conservation Leadership.

It’s been another exciting year in shark and ray conservation policy! Once again, there’s a lot to herald, quite a bit to regret, and much work yet to be done. Here’s my take on the year’s high and low points as well as a preview of key opportunities in 2014. This post obviously reflects my perspective, and is therefore focused on science-based limits on shark and ray fishing and trade. While the work has sometimes been exhausting, and this review is quite long, the scope is by no means exhaustive.

2013 starter with a bang. More specifically, it started with a Bang! Zop! Pow! when I published Five organisms with real super powers that rival their comic book counterparts, a post that set the tenor of my writing style for the rest of the year. The ongoing posts in “Andrew makes lists of ridiculous organisms with tenuous pop-culture connections” have been among the most widely read articles on Southern Fried Science.

David followed suit with his delightfully perverse 50 Shades of Grey Reef Shark: A Valentine’s Day Special Report on Shark Sex (With Pictures! And Video!). Amy kicked of the SFS Department of Human Dimensions in Fisheries Management with Know Your Fishermen as well as your Farmer to which Chuck adds — Fishermen Are Not Evil in his inaugural post. Iris taught us all about Issues facing Puget Sound Chinook salmon in her first post as well.

Here’s how you can tell that the “shark” photobombing kids is actually a dolphin

When California resident June Emerson snapped a photo of her children playing at the beach, she didn’t expect it to generate international news. Although the kids seem to be adorable, that isn’t what captured the attention of the media. In a wave behind them, you can see the outline of a large animal swimming by (or being “terrifying” and “creeping up on them,” as the Daily Mail called it).

Photo by June Emerson, snarky comments by yours truly

The media, including local, national, and international outlets, wasted no time in calling it a shark. However, as Jason Goldman wryly noted, “not all grey things with dorsal fins in the ocean are sharks.” This animal is almost certainly a dolphin. I asked a dozen shark scientists and a handful of dolphin scientists, and all quickly agreed that this is a dolphin.

As I’m no fan of merely appealing to authority (though I’ll trust someone with years of training over the painful to read comments on many of the news pieces), I’ll share with you how we can tell. First, let’s clean up and brighten the image. Since I am not a photoshop master, let’s borrow a cleaned up and enhanced image from KTLA.

Even though the image is somewhat blurry (understandable, as June was trying to photograph her children and not the animal behind them,) there are still easily identifiable features that clearly show that this is not a great white shark, but a dolphin.
