SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Thunnus obesus

SPECIES NAME(s)

Bigeye tuna

It is likely there is one stock of bigeye tuna across the Pacific Ocean. The assessment in the EPO is conducted assuming there is a single population for management purposes {Aires-da-Silve and Maunder 2014}.


ANALYSIS

Strengths
    • There is a catch limit set by the IATTC for the bigeye tuna captured by the longline fisheries of some countries (China, Japan, South Korea, Taiwan and the United States). There is a compromise from the rest of the IATTC's member countries to ensure that their annual catch won't overpass an established level by the organization.
