A lot of debate among conservationists centers on the conflict between the desire to see a species totally protected from human exploitation and the reality that market forces will continue to exist (see the latest on shark fin bans for a very good example). Ideally, a conservation plan should strike a balance, ensuring the continued existence of the species while still allowing people to profit from it in some way. This also requires a clear idea of the limitations of conservation policies. For example, US policies (even the mighty Endangered Species Act) only directly affect populations within the territorial waters of the United States, while international agreements like CITES restrict trade of the species without telling any particular country what to do domestically. However, there are ways to track the interaction between conservation policies and the market, making it possible to make some predictions on how things like fishery management plans and CITES listings might affect trade. Then it gets interesting. Armed with this knowledge, can the market be pushed towards species conservation?

I was incredibly disheartened to find a link to a blog post questioning, yet again, whether social science counts as science, this time by John Horgan at Scientific American. I’ve taken on the myths surrounding my career before, and quite frankly I’m getting sick of it. So this time, I’m going to pick myself up off the floor of frustration and hopefully help move the discussion beyond the same uninformed stereotypes we’ve all heard a million times before. Taken to the extreme, I feel as inaccurately portrayed as the scientist with crazy hair and colored test tubes.
Before I delve into the nitty-gritty, I’d like to tackle the definition of science. There are a number of mostly narrow definitions out there. The one I ascribe to is evidence-based. The research I do is theoretically-grounded, connects research methods to that theory, makes observations using those methods, and then draws conclusions based on that evidence. While this may sound general, science is a broad approach that rapidly sub-divides by discipline and philosophy from there. Now to the less philosophical part…

 If interested citizens want to get involved in conservation and management policy, it’s absolutely vital to use proper terminology. The policy world can be full of confusing jargon, but there are few ways to discredit yourself in the eyes of decision makers as quickly as using a critical term incorrectly. In fact, it isn’t uncommon for a decision maker’s response to a petition or public comment to consist entirely of correcting inaccurate terminology, if a response is issued at all. There are well over 100 acronyms and terms that I’ve seen regularly used, but in the interest of brevity, I’ve selected what I believe to be the 15 most important terms that I’ve seen people repeatedly use incorrectly.
For each term, I’ve provided a definition from a scientific paper or technical report whenever possible. I have also provided some additional explanation in my own words, and some assistance from familiar memes. Whenever possible, I’ve linked to blog posts, articles, or websites that provide even more information. Most of these terms are broadly applicable to fisheries management policy, but some are specific to shark fisheries. It is not my intention with this post to strongly advocate for or against any specific policy (I do plenty of that with other posts), but to make sure everyone is speaking the same language.

As you may have noticed from the previous post, the Atlantic States Marine Fisheries Commission (ASMFC) is proposing draft addendum to the Fishery Management Plan (FMP) for coastal sharks to bring it in line with the current Federal regulations. These regulations are based on the Shark Conservation Act of 2010, which required all sharks fished in US waters to be landed with fins still attached… with the exception of a familiar yet under-studied species known as Mustelus canis, the smooth dogfish. These sharks can still be finned in Federal waters as long as the weight of fins does not exceed 12% of the weight of the finless carcasses. This exception was glaring not just because it singled out one species with a relatively limited range compared to other species in the fishery, but also brought out that seemingly absurd 12% fin-body weight ratio. The addendum is open for public comment until March 28th at 5 pm. With any luck, this post will help clarify some of the issues involved.

President, Shark Advocates International  Sonja Fordham founded Shark Advocates International as a project of The Ocean Foundation in 2010 based on her two decades of shark conservation experience at Ocean Conservancy. 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.
After many months of intense attention to advances in international shark conservation policy through CITES and the European Parliament, it’s time to refocus on sharks in my backyard. A potentially terrible shark policy precedent has been brewing through the Atlantic States Marine Fisheries Commission (ASMFC), and threatens to weaken that body’s coast-wide ban on finning (slicing off a shark’s fins and discarding the body at sea) smoothhounds and other sharks. Help from the concerned public is needed in the final few days of the official public comment for this proposal!

Endangered species seem to be coming up around here more often than usual, mostly due to the potential state-level listing of great white sharks in California. This move has been resisted from some surprising corners, including researchers who are generally pro-shark conservation. The reasons why scientists might want to oppose an Endangered Species listing are laid out by Dr. Chris Lowe in an earlier post on this very blog, so I won’t reiterate all of them here. Surprisingly, I have yet to see any comments accusing Dr. Lowe of being a shill for the drift gillnet fishery.
There seems to a be a real sense among some conservation-minded folks that Endangered Species listing is something of a “holy grail” for species protection and recovery, and some petitioners would have you believe that anything less is unacceptable (and probably the result of corruption). However, the Endangered Species Act has a very specific process by which species receive protection, and a defined set of limitations. A lot of well-meaning people seem to have limited knowledge of this process and limitations. To do my little part to help fix this, this post will be a short primer on the Act and will show how a marine species has recently navigated the entire process for listing. With any luck, maybe this will result in one or two fewer misguided online petitions.

  Dr. Chris Lowe is a Professor of Marine Biology at California State University Long Beach, and is Director of the CSULB Shark Lab. He has studied California’s great white sharks for more than 10 years, and has written more than 75 peer-reviewed scientific publications. Dr. Lowe also serves on the Board of Directors for the American Elasmobranch Society, the world’s largest professional organization of shark scientists. The following guest post was also submitted as a public comment to the California Department of Fish and Wildlife.
Comments for consideration on the petition to list white shark as threatened or endangered species:
I am a Professor of Marine Biology and the Director of the CSULB Shark Lab at California State University Long Beach and have been conducting State and Federally permitted white shark research in California since 2002. In addition, as a professional and published shark scientist who has studied a variety of shark species around the world, including white sharks in California, I would like to take this opportunity to express my personal professional opinion in regards to the petition request and the science behind it.

Hi everyone. I’m Chuck and I used to blog primarily over at Ya Like Dags?, where my main focus was on interactions between apex predators (sharks mostly, but I also occasionally dabbled in other large fish and sea mammals) and those other top marine predators, humans. This was not in the “shark attack” sense, but in the context of fisheries management. Writing about this subject and living it as part of my research have given me valuable perspective on marine science and conservation that I really didn’t have as a freshly-minted Bachelor of Science.
Unfortunately I see more extreme versions of my old perspective show up in countless blog comments, posts, and tweets by perfectly well-meaning people whose only issue is that they’ve fallen for a simplistic, “us vs. them” attitude towards conservation. Consumptive uses of the ocean, such as fishing, are inherently evil and must be opposed. This no-compromise approach sounds cool and may bring in the TV ratings, but is it truly helpful?

 Members of Walking Fish in NC pick up their share, photo by author Fisheries had their ups and downs in the US in 2012. We’ve all heard the stories of overfishing, but there were also a few glimmers of hope as the New England cod fishery proposed to open previously closed areas, the Chesapeake oysters showed slight recovery, and MSC certification expanded and became more popular. News on the social side of the fishery – the fishermen and their families – is not as prevalent outside the small towns where they live. However, some of the most exciting developments happened on this front, starting with official community supported fisheries declaring themselves here to stay. They held a successful summit in New Hampshire this past July, placing them more in the public eye than ever before.

 Today marks the first Tsukiji fish market tuna auction of 2013, and, as in the previous two years, the first fish sold broke all previous records. In 2011, the record breaking tuna sold for $396,000. Last year, we tipped the scales at $736,000. Early this morning, the record breaking bluefin tuna blew the previous records out of the water, fetching a whopping $1,800,000 at the auction block, making this 488-lb tuna the most expensive fish ever purchased.
Over the next few weeks, I’m certain that we’ll see this number presented as an argument against bluefin tuna fishing, as an example of an industry out-of-control, and as a symbol of how ruthlessly we’ll hunt the last few members of a species to put on our dinner plates. These issues are reflected in the tuna market, but I want to urge caution in drawing too many conclusions from this record breaking number.
