Project Description
SEDAR 65 addressed the stock assessment for HMS Atlantic blacktip shark. The Data Workshop was held October 29 – November 1, 2019 in Charleston, SC, the Assessment Process was conducted via webinars from February through August, 2020, and the Review workshop was held October 29 – November 5, 2020 via webinar.

Working paper findings and methods may change following workshop review. Working papers should not be cited without author permission.
