CAPAM workshop identifies stock assessment good practices to improve tuna assessments
The Center for the Advancement of Population Assessment Methodology (CAPAM), New Zealand’s National Institute for Water and Atmospheric Research (NIWA), and the International Seafood Sustainability Foundation (ISSF) held a technical workshop on Good Practices for tuna stock-assessment on 7-10 March 2023 in Wellington, New Zealand. The workshop was coordinated by past IATTC staff member Simon Hoyle and current Head of the IATTC Stock Assessment Program Mark Maunder. Mark also chaired the meeting. In person and virtual presentations were made by invited experts from both the tuna world and fisheries in general. Over 40 people attended in person and over 100 virtually. IATTC staff members Haikun Xu and Carolina Minte-Vera also attended in person and staff members Cleridy Lennert-Cody, Juan Valero, Anandamayee Majumdar, and Dan Ovando attended virtually. Carolina Minte-Vera was the keynote speaker for stock structure, Cleridy Lennert-Cody was the commenter on purse seine species and size composition data, and Mark Maunder was the keynote speaker for selectivity. The workshop successfully delivered its goal on the last day by discussing an initial list of ‘Good Practices’ for implementing stock assessments for tuna stocks, which will be further refined for the workshop report. These Good Practices will be used for the IATTC benchmark assessments of all three tropical tunas (skipjack, yellowfin, and bigeye) in the EPO in 2024.
