Project Description
SEDAR 21 addresses stock assessments for HMS species sandbar, dusky, and blacknose sharks. The Data Workshop was held June 21 – 25,2010 in Charleston, SC, the Assessment Process was conducted via a series of webinars between September 2010 and March 2011 and the Review workshop was held April 18-22,2011 in Annapolis, MD.
