In this study, based on the basic theory model ¢wGordon-Schaefer model is used to discuss the equilibrium levels for yellowfin tuna in the Western and Central Pacific of open access (OA) and present value maximization (MPV). And then to compare the catches and the stocks on the two model¡¦s equilibrium value, the result shows the management of yellowfin tuna in the Western and Central Pacific tend to MPV model, the regional fisheries organization (RFMO) to detect the implementation of the measures (MCS) is significant; in addition, use sensitivity analysis and then to understand the changes on the stocks and the effort quantities effected by varying different parameters. In OA, if you want to get effectively maintain the sustainability of the stocks, should be considered to reduce the price and the catch coefficient, increase the cost per unit of effort to control; in MPV, we can understand that the catch coefficient and the intrinsic growth rate have a bigger influence in the effort quantities; Finally, by simulating the catches and the stocks, that if it can continue to effectively manage fishery by MCS in the future, the catches and the stocks of yellowfin tuna will tend to balance the value of MPV, and so on, not only resources effective use of maximum profit and maintaining our fleet of ocean-going business interests, but also resources can be sustainable.
