“At-sea cruises provide good stepping stones for further work and remind us that improving fishing practices is an iterative process.”
In a blog for ISSF, Dr. Melanie Hutchison, a participant in ISSF-supported scientific fieldwork, reflects on ISSF’s shark bycatch and tuna research in three oceans.
International Workshop on Mitigating Environmental Impacts of Tropical Tuna Purse Seine Fisheries
A report summarizes a workshop held to review research and advocacy activities on mitigating environmental impacts of tropical tuna purse seine fisheries, with emphasis on bycatch and FADs. Workshop participants included scientists, as well as representatives from NGOs, tuna RFMOs, manufacturers, and purse seine fishing companies.
The workshop was co-sponsored by the Common Oceans ABNJ Tuna Project and focused on six sessions: (1) Bycatch of the tuna purse seine fishery, (2) sharks and rays, (3) small bigeye and yellowfin tuna, (4) FAD structure impacts, (5) FAD management, and, (6) looking ahead: the next 10 years.
The report summarizes the main points made during presentations and discussions and offers data-rich presentations for each session.
Each graphic highlights a particular region.
First, the graphic shows the percentage of the catch that is either target tuna or bycatch — in each ocean region, and based on set type (fish aggregating device or FAD, free school, and dolphin). Then, the graphic takes a closer look at a particular-set-related bycatch in the highlighted ocean region, with percentages for each marine species.
Used in combination, four actions can increase silky shark survival in purse seine fisheries by 62%
The International Seafood Sustainability Foundation (ISSF) is a global coalition of scientists, the tuna industry and World Wildlife Fund (WWF) — the world’s leading conservation organization — promoting science-based initiatives for the long-term conservation and sustainable use of tuna stocks, reducing bycatch and promoting ecosystem health. Helping global tuna fisheries meet sustainability criteria to achieve the Marine Stewardship Council certification standard — without conditions — is ISSF's ultimate objective.
