Project Description
SEDAR 28 addresses stock assessments for Gulf of Mexico and South Atlantic Spanish mackerel and cobia. The Data Workshop was held February 6-10, 2012 in Charleston, SC, the Assessment workshop was held May 7-11, 2012 in Miami, FL and the Review workshop concerning South Atlantic stocks was held October 29-November 2, 2012 in Atlanta, GA. Gulf stocks will undergo a CIE Desk Review.
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.
