Webinar Recording Now Available: Can a new approach provide reliable estimates of shortfin mako shark abundance and productivity in the Atlantic Ocean?

November 14, 2019 — The following was released by the LenFest Ocean Program:

On Wednesday, November 13, Dr. Mark Bravington of Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) discussed his work to improve the information used to assess and manage shortfin mako sharks in the Atlantic Ocean.

A recording of the webinar is now available and can be accessed here.

For the past several months, Dr. Bravington has been examining the feasibility of a genetic method known as close-kin mark-recapture for estimating shortfin mako shark abundance in a way that avoids the limitations and biases associated with estimates collected through fishing activities. Such a tool could help fisheries scientists develop more accurate stock assessments to inform effective management strategies for this species, which is overfished in the North Atlantic.
