Progress: It’s now only legal to remove fins at sea for one shark species in the United States

Shark finning, the process of removing shark fins at sea and dumping the rest of the body, is nearly universally opposed by conservation activists, scientific researchers and fisheries managers. In addition to being potentially inhumane (the shark is often still alive when dumped overboard,) this processing method is exceptionally wasteful and makes it very difficult for fisheries managers to get accurate species-specific catch data.

There are severals ways to stop shark finning. One is to ban fishing for sharks entirely, fins of sharks can’t be removed at sea if sharks aren’t caught in the first place. It is important to note that some well-intentioned activists  use “stop shark finning” as a synonym for “stop shark fishing of any kind,” but that is unequivocally not what shark finning is and not what finning bans accomplish. The second method is through the use of fin to carcass ratios. Under these policies, fisherman can remove the fins of sharks at sea as long as the total weight of fins landed does not exceed a certain percentage (usually 3.5 to 5%) of the total weight of carcasses landed. This can still leave room for some undetected finning (these ratios vary by species and fin removal method) and still makes it difficult for managers to know how many of each species are being caught (sharks are more readily identifiable when their fins are intact). Finally, a method growing in popularity in recent years, which is generally considered to be a best practice of shark fisheries management, is the requirement of landing all caught sharks with “fins naturally attached.”

inigo-montoya-you-keep-using-that-word-i-dont-think-it-means-what-you-th-3b4b2920-sz625x625-animateIf 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.
