Estimating fishing capacity is one of current hot issues in the international fisheries. It is because thatincreased fishing capacity has caused not only fish stocks to be reduced, but also additional fishing costs tobe incurred without additional incomes, which resulted in decrease of economically viability of fisheries. Inorder to solve this problem, FAO adopted rthe International Plan of Action for the Management of FishingCapacitysin 1999 and recommended that member countries to measure fishing capacity and to implementthe domestic action plan to reduce excess fishing capacity. This study is aimed at assessing fishing capacityof the octopus coastal trap fishery(OCTF) using data envelopment analysis(DEA) which is a methodrecommended by FAO. The DEA results on 10 individual OCTF vessels showed that the capacityutilization(CU) was a 0.93 on average, indicating some differences in CU among vessels(0.791.0). Inaddition, results of the sensitivity analysis revealed that under the current level of catch, the gross tonnage,horse power, days fished, and traps per trip could be reduced by 35%, 33%, 16%, and 18% on average,respectivelyKey words : Fishing capacity, Data envelopment analysis(DEA), Trap fishery, Octopus
