Skipjack (Katsuwonus pelamis L.) needs to be managed well as a renew¬able natural resource but vunerable to depletion or extinction. One approach in fish resource management is by modeling. Analysis was carried out, aimed to get the best model for surplus production model, to assess the Maximum Sustainable Yield (MSY), and to get the skipjack utiization and effort level. Data used for surplus production model were collected from skipjack landings data provided by Marine and Fisheries Seivice (Dinas Kelautan dan Perikanan) of North Sulawesi Province. The best Surplus Production Model that can be used to assess the skipjack potential yield is the Schaefer model. The optimum effort per year biologically EMsyis (38,319 trip). The optimum yield biologically CMSY is (34,504,39 ton). Utilization level in 2003 is 106.60% with effort level 96.96 %. The catch in 2003 is already above the MSY value, which shows an overfishing.
