Atlantic Sharks at Risk: An Expert Working Group Report

Oct 27, 2008

Dr. Colin Simpfendorfer and the Lenfest Ocean Program convened an international expert working group to estimate the risk of overfishing for twelve pelagic, or open ocean, shark and ray species caught in Atlantic pelagic longline fisheries under the jurisdiction of the International Commission for the Conservation of Atlantic Tunas (ICCAT). The scientists conducted an integrated risk assessment designed for data-poor situations for these sharks and rays. Their analysis indicated that bigeye thresher, shortfin mako and longfin mako sharks had the highest risk of overfishing while many of the other species had at least moderately high levels of risk. Based on these results, the scientists developed recommendations for limiting or prohibiting catch for the main pelagic shark and ray species taken in ICCAT fisheries.
