A few weeks ago, H.R. 5248, The Sustainable Shark Fisheries and Trade Act, was introduced into Congress. The purpose of this bill is to “encourage a science-based approach to significantly reduce the overfishing and unsustainable trade of sharks, rays and skates around the world and prevent shark finning,” according to a press release from Mote Marine Lab.
Though the devil is always in the details, and I’ll get into those below, here is a general overview of how this would work. The Sustainable Shark Fisheries and Trade Act would direct NOAA Fisheries to evaluate the fisheries management practices of other shark and ray fishing nations. This is similar in principle to other things NOAA is already doing, and a similar role for NOAA was included in the 2010 Shark Conservation Act (but has yet to be implemented).
Nations that have sustainable fisheries management practices comparable to ours (or certain fisheries associated with those nations, even if other fisheries are less well managed) will get a formal certification of their sustainable management practices, and nothing will change for them. Nations (or fisheries) that are found to not have sustainable fisheries management practices comparable to ours will not be allowed to have those products imported into the US and sold in our markets until their management practices improve. In the meantime, they’ll have access to NOAA’s existing capacity building resources and expertise to improve their own practices.
I support much of what this bill is trying to do, but I have some significant concerns about some of the current phrasing and plan for implementation.

The United States Congress is considering a nationwide ban on buying, selling, or trading shark fins. While several of my posts and tweets have briefly discussed my stance on such policies, I’ve never laid out my full argument in one post. Here is why I, as a shark conservation biologist, oppose banning the shark fin trade within the United States. The short answer is that the US represents a tiny percentage of overall consumers of shark fin, but provide some of the most sustainably caught sharks on Earth, as well as important examples of successful management, to the world. This means that banning the US shark fin trade won’t reduce total shark mortality by very much, but will remove an important example of fins coming from a well-managed fishery while also hurting American fishermen who follow the rules. Also, a focus on these policies promotes the incorrect belief that shark fin soup is the only significant threat to sharks, and that addressing the tiny part of that problem locally represents the end of all threats. For the longer answer, read on. And for the case for shark fin bans, please see this guest post from Oceana scientist Mariah Pfleger.
Earlier today SeaWorld announced to the media that it was making major changes in its practices when it comes to marine wildlife. The announcement comes after years of bad publicity and failing stock prices as the result of the documentary Blackfish, criticism from marine mammal and marine conservation scientists and an unrelenting social media campaign by online activists. The changes announced are a major paradigm shift for the company and include:
In both my professional and private life, I am a man who wears many hats. I am a deep-sea ecologist, a science writer, a goatherd, a geneticist, a conservation advocate, a grill master, and many others. When David asked me to join him in co-authoring “Trophy fishing for species threatened with extinction: A way forward building on a history of conservation” I did so not in my capacity as a marine science Ph.D., but as a recreational fisherman who cares deeply about the survival of his sport. Without fish, there is no fishing.
I was, at first, skeptical, but over the course of a summer, I came to appreciate what David was trying to accomplish.
I wrote most of my thesis on this boat, with a rod in the water.
Before I talk about fish, I need to talk about birds.
My family loves to watch movies, which presents a problem during the few times we’re all together: there are very few good movies that none of us have already seen. This past Thanksgiving, we resolved that dilemma by watching some “based on a true story” garbage starring Nicholas Cage and the star of High School Musical, a plot-less but action packed shoot ’em up starring the governator and Sawyer from Lost, and “Cloudy with a Chance of Meatballs.”
Based on a popular children’s book, Cloudy with a Chance of Meatballs tells the story of Flint Lockwood, a young inventor who keeps trying to make life better for people in his small island town of Swallow Falls. His inventions always backfire, including the titular invention that makes the sky rain food. In the sequel, which I watched this past weekend because shut up I enjoyed the first one leave me alone, we learn that some of the food has become sentient. Swallow Falls is now home to a unique ecosystem that includes watermel-ephants, taco-diles, fla-mangos, and many other hybrids called foodimals. In addition to featuring some of the best puns I’ve ever seen, these movies also raise some interesting questions about ecology, sustainability and conservation.
Though the fisheries news cycle has mostly been taken up by the 15-year anniversary of the Sea Around Us project (and some choice words between researchers), today also marked the official announcement of the 12-month finding on the petition to list dusky sharks on the U.S. Endangered Species Act. Long story short, the National Marine Fisheries Service has decided that the dusky shark population in the Northwest Atlantic doesn’t need ESA protection to avoid extinction. While it may be tempting to decry NMFS’ decision as falling short for a species that has long been a prime example of declining shark populations, what it actually means is that things are looking up for the dusky shark. Finding that out only takes a little reading into the decision documents.
The 2010 Shark Conservation Act prohibits removal of fins at sea for all sharks landed in U.S. Waters, with a glaring exception for smooth dogfish, or smoothhound sharks. In an effort to ensure that fishermen aren’t performing the cruel practice of throwing a still-living but finless shark overboard, a fin:body ratio of 12% for smooth dogfish became law as part of this bill. This means that the total weight of smooth dogfish fins cannot be more than 12% of the total dressed weight of the bodies when the sharks are landed.
Some time ago I wrote a post questioning where this 12% ratio came from, especially since the best available published literature at the time suggested a ratio of only 3.5% for smooth dogfish. The Atlantic States Marine Fisheries Management Commission (ASMFC) responded, claiming that they had data backing up a find:body weight ratio of 7-12%. Now, thanks to the SEDAR stock assessment workshop for this species, the study conducted by the ASMFC is publicly available (albeit nearly four years after it was written into the law).
So where does this seemingly extremely high fin:body ratio come from? It depends on how you slice it.
Many years ago, I was offered a job doing restoration work at a coal company while perusing festival booths in Fairbanks, Alaska. Still wearing my college-aged rose colored glasses, I was skeptical of working for conservation within industry, said thanks-but-no-thanks, and returned to upstate New York to finish my degree. Looking back, I honestly believe I could have enacted more positive change for the earth had I taken that job than I have in the almost decade since.
I recall this story because while at a recent all-volunteer biodiversity festival, a friend asked me ‘why can’t people do all this great work as their paid work?’ A group of us stood around silently for a few minutes, realizing that this question derived of innocent curiosity delved deep into issues of societal values, our current economic system, and conservation philosophy. In short, the answer is that because conservation brings in none of its own revenue, but depends on the tax money or philanthropy of others. When that dries up, no conservation careers are available. And even when they are, a high percentage of time on the job is spent looking for future funding through grants. Read More
This past Tuesday, the draft bill to reauthorize the Magnuson-Stevens Act was released by the U.S. House. The Magnuson-Stevens Act is a big deal because this is the law that lays out how fisheries management works in the United States. This time, a number of changes have been proposed by Representative Doc Hastings, some of which could fundamentally change fisheries management and fisheries science in U.S. waters. The proposed changes immediately became controversial, garnering overwhelming support from witnesses to the House Natural Resources Committee hearing of the bill (witnesses included representatives from the recreational and commercial fishing industries as well as the Mid-Atlantic Fishery Management Council) while the Pew Charitable Trust strongly opposed the bill, calling it the “Empty Oceans Act” (translated into GIFs by Upwell for your viewing pleasure).
How might the Hastings bill affect your favorite marine species (both in the water and on your dinner plate)? Read on to see the good, bad, and ugly aspects of these proposed changes, at least according to this particular fisheries scientist.
In 1999, government officials from all over the world gathered in Rome for a meeting of the United Nations Food and Agricultural Organization’s Committee on Fisheries. The Committee meets every two years, but one of the numerous outputs of this meeting was particularly significant, at least for sharks. Based on years of consultation and discussion by experts, the group agreed on a formal set of general principles that should make up sustainable and well-managed shark fisheries.
These 10 principles, part of a larger International Plan of Action for Sharks (IPOA-Sharks) , have helped shape more than a decade of scientific research and management priorities for the chondrichthyan fishes. When properly implemented and enforced, they allow people to use sharks (and rays and skates and chimeras, included in the IPOA-Sharks definition of “sharks”) as a natural resource while keeping populations healthy and allowing depleted stocks to recover.
According to the IPOA-Sharks, a national shark plan should aim to:
