This report provides a review of our knowledge of the bycatches, defined as
discarded dead, from the tropical tuna purse seine fisheries of the world. The major
fishing grounds involved (eastern and western Pacific, eastern Atlantic, and western
Indian Oceans) share the gear, the ways of fishing, and the structure of the pelagic
communities. Because of that, the species taken in association with tuna schools tend
to be the same in all regions.
The Bycatch Management Information System (BMIS) focuses on bycatch mitigation and management in oceanic tuna and billfish fisheries*. It is an open resource useful for fishery managers, fishers, scientists, observers, educators and anyone with an interest in fisheries management. As a reference and educational tool, the BMIS aims to support the adoption and implementation of science-based management measures so that bycatch is managed comprehensively and sustainably.
