DINAMICS OF SUSTAINABLE WELFARE FISHERIES BASED ON TUNA FISH SENDANG BIRU, MALANG (DINAMIC SYSTEM APPROACH).

This study was developed as a dynamics system model which is integrated tuna stocks, social economic and policy sub models. This model was developed based on historical data, than development into three development scenarios: with fish cact limitation, limitation by sustainable yield (MSY) limitation by maximum economic yield (MEY) and open access equilibrium (OAE). System dynamic modeling was conducted to analyze sustainable tuna and sustainable income of tuna fishermen based on various points of view to get the better management of sustainable tuna fisheries.
