Project Description
SEDAR 77 will address the stock assessments for HMS Hammerhead Sharks. Hammerhead Stock ID will be resolved prior to the start of the SEDAR 77 Data process through a series of Stock ID webinars. The Data process will be a series of webinars and a in-person workshop to be held December 2021. The Assessment Process will be a series of webinars; and the Review Workshop will be in 2023.
For more information, please contact the SEDAR Coordinator for this project, Kathleen Howington: kathleen.howington@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.
