Conservation, fisheries, marine science, Natural Science, Science, sharksNovember 3, 20140

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 […]

The United States National Marine Fisheries Service just released the 2013 “fisheries of the United States” report. The extremely detailed report contains lots of important information on both recreational and commercial fisheries in U.S. waters, and I recommend giving it a thorough read.

Fin-Body Ratios for Smooth Dogfish – Depends on How You Slice It

Conservation, fisheries, Focus on Nuance, sharks, Sustainability, Underrepresented Issues in Marine Science and ConservationAugust 8, 2014
