Abstract


Optimum biologically and economically utilization level of fishery resources should be determined earlier in order to avoid it from over-exploitation. This issue is crucial, because currently many valuable fishery resources are extinctly in danger as a consequence of over-fishing. The objective of this research is to determine bio-economic equilibrium of Skipjack (Katsuwonus pelamis) resource in Banda Sea. Data were collected by interviews using questionnaire, and analyzed using Gordon-Schaefers method combined with Fox Algoritm. The results showed that biological equilibrium (MSY) of Skipjack in Banda Sea and the waters surrounding attained at annual production capacity of 30.954,65 ton, with optimum efforts level (EMSY) of 21,251 trips per annum. Meanwhile, the maximum economic yields (MEY) was attained at efforts level of 20,431 trips per annum with production size ((hEMY) was 32.905,91 ton per annum. Economical equilibrium was produced at open access condition with efforts level of 40.862 trips per annum and production of 4.889.98 ton per annum. Optimum utilization of lower biological and economical pressures was at efforts level of 20.431 trips per annum and production size was 32.905,91 ton per annum.
