Project Description
SEDAR 50 was a joint assessment between the South Atlantic Fishery Management Council (SEDAR Lead) and the Mid-Atlantic Fishery Management Council and addressed the stock assessment(s) for Atlantic blueline tilefish. A Stock ID Work Group meeting was held June 28-30, 2016 in Raleigh, NC; the Data Workshop was held January 23-27, 2017 in Charleston, SC; the Assessment Process was a combination of a series of webinars and an in-person workshop held the week of May 22nd, 2017 in Atlantic Beach, NC; and the Review Workshop was August 2017 in Atlantic Beach, NC. For more information, please contact the SEDAR Coordinator for this project, Julia Byrd: julia.byrd@safmc.net.
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.
