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.

Right now, delegates from 178 countries are meeting in Bangkok, Thailand to discuss a variety of conservation proposals. At the 16th CITES Conference of the Parties, among many other worthy topics, delegates will be debating a record-number of shark and ray proposals. These include iconic species like hammerhead sharks (3 species) and manta rays (2 species), as well as oceanic whitetip sharks, porbeagle sharks, and three species of freshwater stingray.
In addition to a record-number of shark and ray proposals, this year’s Conference of the Parties also has a record-number of attendees live-tweeting the meeting.Those of you who follow me on twitter know that I’ve been re-tweeting lots of information about CITES and these shark conservation proposals. In case you want to get the information directly from the source, I’ve prepared a guide to following along with the meeting on twitter.
1) Follow #CITES . Though this hashtag isn’t exclusively focused on sharks (and isn’t exclusively in English), there’s a lot of good information being shared.
2) Follow #Cites4Sharks . Also use this hashtag if you’re sharing any relevant links or information.
3) Follow the 13 accounts I’ve highlighted below (and let me know in the comments if you have suggestions for any accounts I should add to the list):

 Sonja Fordham 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.
The last twelve months added up to another exciting year in shark and ray conservation policy. We certainly saw and should herald a lot of great progress in 2012. I think it’s also important to acknowledge what went wrong so we know where we stand and how best to move forward. I’ve taken a look back and compiled a top ten list of what I see as the best and worst events in shark fisheries management for 2012, based on my work at Shark Advocates International. I’m starting with the low points, but keep reading! It ends on a high note.

While the rest of the scientific and management community and I are grateful for the passionate support of many shark conservation advocates, passion is no substitute for knowledge and accuracy. Some conservation issues are a matter of opinion and can (and should) be reasonably be discussed by people with different views, but many others are a matter of fact. Presented here, in no particular order, are 13 incorrect statements and arguments commonly made by well-intentioned but uninformed shark conservation advocates, along with the reality of the situation.
 From MemeGenerator.net
1) “Shark finning” is synonymous and interchangeable with “the global shark fin trade.” Shark finning is a specific fishing method. It is not the only way to catch sharks, and it is not the only way to provide shark fins for the global fin trade. Stopping shark finning is a worthy goal (that has largely been accomplished already *) because it is a wasteful and brutal fishing method that complicates management, but stopping shark finning does not stop the global shark fin trade. Many people calling for a ban on finning really seem to want no shark fishing and no fin trade of any kind (a viewpoint I disagree with, but regardless, proper terminology matters). For more on the difference between shark fishing and shark finning, see this post from June 2012.
2) 100 million sharks a year are killed for their fins. The origin of this number is still debated, but it was popularized by Sharkwater. While we will likely never know exactly how many sharks are “killed for their fins”, the best scientific estimate of the scope of the fin trade we have comes from a 2006 paper by Dr. Shelley Clarke. She found that the fins of between 26 and 73 million sharks end up in the fin trade each year, with a simulation average of 38 million. Dr. Clarke wrote an essay for SeaWeb on the misuse of her work, which is worth a read.
3) 1 in 3 species of sharks face extinction. This one is actually relatively close to accurate, and can be fixed with the addition of just two words. An IUCN Shark Specialist Group report found that 1 in 3 species of “open ocean” sharks are Threatened with extinction (Threatened means Vulnerable, Endangered or Critically Endangered according to IUCN Red List standards). 1 in 6 species of shark, skate, ray, or chimera are Threatened- while still a troubling number indicative of a very bad situation, it’s half as bad as claimed by many advocates. Also, please note that I included skates and rays, which are similarly threatened but often ignored by conservation advocates (with one notable exception from 2012).

A newly-released list of proposed amendments for the upcoming CITES Conference of the Parties includes proposals to protect ten species of sharks and rays, a record-breaking number. These include three species of hammerheads, oceanic whitetip sharks, porbeagle sharks, three species of freshwater stingray, and both species of manta ray.
In total, 37 countries are involved in the proposed amendments. As expected, the United States is a co-sponsor of the oceanic whitetip measure. Additional noteworthy participants include major shark fishing nations like Mexico (co-sponsoring the hammerhead proposal) and the European Union (co-sponsoring the hammerhead and leading the porbeagle proposals).
“International trade is a major driver for shark fisheries around the world, and yet controls on this exploitation are woefully insufficient,” said Sonja Fordham, President of Shark Advocates International. “We are grateful for continued U.S. leadership in addressing international shark trade, and welcome this unprecedented number of proposals to safeguard these vulnerable species under CITES.”
Threats to these animals are diverse and include directed catch for both fins and meat, bycatch, alternative medicine (gill rakers), and even the aquarium trade. Each of the freshwater stingray species are considered Data Deficient by the IUCN Red List, scalloped and great hammerheads are considered Endangered, and the other species are Vulnerable.
Species of elasmobranchs currently protected by CITES include the great white shark, whale shark, basking shark, and all species of sawfish. Porbeagles, oceanic whitetips, and hammerheads were proposed for CITES protections in 2010, but the measures failed.
Each of these proposals aims to list a species under CITES Appendix II, which requires that any international export of these species be certified as sustainable (including the issuing of permits). The discussion will take place next March at the 16th CITES Conference of the Parties in Bangkok, Thailand.

All eyes in the shark world are focused on Belgium, where the European Parliament’s Fisheries Committee votes Wednesday on one of the most significant conservation policies in years: a stronger EU-wide ban on shark finning via a prohibition on removing sharks at sea, with no more exceptions. Since some of the details are quite technical, emotions are running high, and a lot of misinformation is spreading, I’ve prepared a quick guide to help our readers understand the proposed policy. For much more detailed updates, follow the Shark Alliance’s blog.
1) The proposed policy would strengthen the current EU finning ban, not ban fins. As has previously been discussed, some of the language surrounding shark conservation policy can be confusing. As a reminder, shark finning is the act of removing fins from a shark at sea and dumping the body overboard. Finning of live sharks is incredibly inhumane (the “finned” shark will bleed to death or drown when dumped overboard), and incredibly wasteful whether the shark is alive or dead (less than 5% of the shark is used). Scientists are almost universally opposed to shark finning because it is often associated with unsustainable fishing and the practice makes it difficult for managers to know what species of shark the fin came from. The policy that the European Parliament is voting on is an amendment to the current EU ”finning ban”,” which relies on a complicated and lenient fin to carcass ratio for enforcement. The European Commission has proposed requiring that sharks be landed with fins still attached, which would strengthen enforcement and data collection capabilities. This is not a “fin ban” that would make it illegal to buy, sell, or possess fins.

Shark finning, one of the most wasteful, unsustainable, and inhumane methods of gathering food in the history of human civilization, has rightly become a hot topic in the marine conservation movement. However, there is a great deal of confusion among activists concerning this problem and the best way to solve it. Those of you who follow me on twitter have seen me point out numerous recent anti-finning “awareness campaigns” which feature photographs of sharks that have not actually been finned.
Shark finning does not mean removing the fins from a shark. This is really important and seems to be a source of some confusion- not every shark fin for sale in markets is the result of shark finning! Shark finning means removing the fins from a shark while still on the fishing vessel and dumping the rest of the shark overboard. This is a problem because its wasteful (less than 10% of the weight of a shark is used), because its easy to quickly overfish a population even from a small boat (fins don’t take up a lot of space on board), and because its almost impossible for managers to know how many of each species were harvested. As stated above, this practice is also shockingly inhumane, as the sharks are often still alive when they are dumped overboard.

At the 2nd International Marine Conservation Congress, Dr. Nick Dulvy and the IUCN Shark Specialist Group organized a special symposium called “Securing the Conservation of Sharks and Rays”. This symposium featured leading scientists, international policy experts, the founder of a creative non-profit, a National Geographic conservation photographer… and me. It was, without a doubt, the greatest professional honor of my (admittedly brief so far) career.

Meet Captain Bill Goldschmitt, an author, blogger, and commercial shark fisherman. Captain Bill is a passionate, opinionated, and influential man in the world of shark conservation and management. Unfortunately, the opinions that he chooses to passionately share are wildly incorrect. Captain Bill is a leading proponent of many ideas that have no basis in reality, including the notion that shark conservation efforts lead to an increased danger for humans from shark attacks.
He repeats this idea often on his blog. In recent months, he has written that the Florida Fish and Wildlife Commission has declared “open season” on Florida bathers by even considering new shark protection efforts, pleaded with Shark Week to focus more on how dangerous sharks are and less on their dwindling numbers and ecological importance, and compared shark conservationists to those who apologize for al-Qaeda terrorists.

Earlier today, the California legislature voted to approve AB 376, the excitingly titled “act to add section 2021 to the Fish and Game Code, relating to sharks”. The ocean conservation community is happy, and we should be. The bill and its backing from Hollywood stars have generated substantial media coverage of the plight of sharks, and, if signed into law by the Governor and properly enforced, it could well save a lot of sharks. However, fin bans aren’t the perfect solution to the shark conservation crisis, and we still have a lot of work to do to protect sharks and closely related species around the world.
