Preparation of catch database for Atlantic bigeye tuna and its application.
NIPPON SUISAN GAKKAISHI, 1988 The catch database of the bigeye tuna Thunnus obesus by longline fisheries in the Atlantic Ocean was constructed in aims to establish the effective fishing operation for the decision of the fishing ground. The monthly data of the bigeye tuna catch by each 5-degree square were input in this database, with the published data from the “Annual report of ...

Genetic evidence for inter-oceanic subdivision of bigeye tuna ( Thunnus obesus ) populations
Marine Biology, 1998 Bigeye tuna (Thunnus obesus Lowe, 1839) are a commercially important species of tuna found in the Atlantic, Indian, and Pacific oceans. To initiate an analysis of bigeye tuna population-structure, three PCR–RFLP assays were developed based on the published mtDNA control-region sequences of four bigeye tuna.
