Project Description
SEDAR 33 addresses stock assessments for Gulf of Mexico gag grouper and greater amberjack. The Data Workshop was held May 20-24, 2013 in Tampa, FL; the Assessment Process was held via webinars August through October 2013; and the Review workshop was held February 24-27, 2014 in Miami, FL. For more information, please contact the SEDAR Coordinator for this project, Ryan Rindone: ryan.ryndone@gulfcouncil.org.
NOTE: SEDAR Working papers document the methods, datasets, and preliminary analyses that are under consideration at the various workshops and therefore do not necessarily represent final consensus opinions of workshop participants. Working paper findings and methods may change following workshop review. Working papers should not be cited without author permission.
