Processes and results of stock enhancement of tiger shrimp performed in Batan Bay in Philippines was reported as a trans-disciplinary research for enhancement of area-capability (AC). Causes of decline in catch amount of tiger shrimp were overfishing and degradation of its nursery grounds such as mangrove forest. Five fishers had participated in the intermediate culture throughout the project period. Technical issues for stock enhancement were solved and expectable recapture rate of released shrimp was more than 20%. Economic feasibility of the stock enhancement was also confirmed. Forty-five percent of the people in the area are realizing the increase of catch amount of tiger shrimp. Effectiveness of stock enhancement is obtaining understanding from common people including public administrations. After the project, the stock enhancement was paused and stakeholders want to proceed with the stock enhancement. Aklan State University is planning to support stock enhancement project as its extension activities and expect participations of researchers from foreign countries. Such activities will provide research opportunities for evaluation and theorization of AC.
