New paper: What happened to the world’s first certified sustainable shark fishery?

June 26, 2023 David Shiffman

In 2011, the world’s first fishery for sharks was certified as sustainable by the Marine Stewardship Council*. The British Columbia spiny dogfish fishery made major news in fisheries management and ocean conservation world, where the possible existence of sustainable shark fisheries has been debated intensely. A few years later, the fishery voluntarily withdrew their certification, and never publicly said why.

I wanted to know what happened with this scientific mystery. So, with the help of Chuck Bangley and Catherine Macdonald and funding support from the Liber Ero Postdoctoral Fellowship program, I organized a research expedition to find out. The results of our expedition can be found in our new paper (LINK,) (OPEN ACCESS AUTHOR COPY) but in this blog post, I’d like to explain what we did, what we found, and why we think it’s important.

Good morning. The time is now 2 minutes to mid-night. Doomsday Has Never Been Closer. Good luck.

Despite the fact that we live in extremely dangerous times, the scientists in charge of the clock said there is hope. The clock has been wound backwards before, in the wake of the Cold War or during times when nuclear superpowers expressed interest in not mutually assuring destruction.

The scientists argue that civil society should turn the screws on government to reduce carbon emissions and push for even more ambitious climate action than what the Paris Agreement calls for. That sounds like a more fruitful plan than huddling in a bunker.

The fight for our Marine National Monuments isn’t over. We finally know *some* of the contents of Zincke’s monument review memo, and it’s not great. The DOI wants to see commercial fishing return to the Pacific Remote Islands and Rose Atoll Marine National Monuments. Longline fishing in these regions has historically been conducted by foreign fishing fleets which have been documented using slave labor. Many ecologists believe that maintaining these protected zones serve as a refuge that boost populations of many important commercial fish and improve the overall health of the fishery.
Here’s the good news: Any change to monuments created under the Antiquities Act must be approved by congress. You’ve got a lot of reason to call you representatives this week, so why not add “I opposed the reintroduction of ecologically and economically destructive commercial fishing to the Pacific Remote Islands and Rose Atoll Marine National Monument.” to your script?
