Week 25: Pacific Bluefin Tuna Rebound to New Highs

New stock assessment reveals largest recorded biomass since assessments began.

The recovery of Pacific bluefin tuna has achieved a major milestone—the species exceeded international targets a decade ahead of schedule. The rebuilding of Pacific bluefin tuna reflects a fisheries management success. International organizations cooperated across the Pacific to reverse decades of overfishing for the prized species.

The International Scientific Committee for Tuna and Tuna-Like Species in the North Pacific Ocean (ISC), including NOAA Fisheries researchers, provided scientific expertise to inform conservation measures. The Inter-American Tropical Tuna Commission (IATTC) and Western and Central Pacific Fisheries Commission (WCPFC) adopted these measures.
