Spatial and Temporal Distribution Patterns of Bigeye Tuna (Thunnus obesus) in the Indian Ocean


1985-1999


The spatial and temporal distribution patterns of bigeye tuna (Thunnus obesus) in the Indian Ocean were studied based on catch data of Taiwanese longline fishery during the period 1985~1999. We used a geographic information system (GIS) to compile a fishery database to statistically explore the catch per unit effort (CPUE), mean weight distribution, and the relationship between distribution and environmental factors. Results indicated that bigeye tuna were mainly distributed in tropical waters between 10􀄘N and 15􀄘S, although some scattered instances of high catches appeared outside this range.
