This paper proposed a novel intelligent data processing model which applied to fishery forecasting based on the Indian Ocean bigeye tuna fishery application background.

Feeding behavior of Thunnus obesus in the west-central Indian Ocean;

The relationships between the thermocline and the catch rate of Thunnus albacares and Thunnus obesus in the high seas of the Indian Ocean;

Hooking rates distribution of Thunnus obesus in tuna longlining ground and its relationship with SST in the western tropical Atlantic Ocean;

Relationship between vertical distribution of bigeye tuna (Thunnus obesus) and water temperature in Indian Ocean;

Preliminary study on correlation of temperature difference of 50 to 150m water layers versus longline hooking rate of bigeye tuna (Thunnus obesus) in the Indian ocean;

Relationship between bigeye tuna vertical distribution and the temperature, salini-ty in the Central Atlantic Ocean;

Studies were conducted to analyze the tuna resources of major economic species,and to elaborate the current situation and problems of deep-sea tuna fishery development.
