The compatible fishing capacity to some quota controls in key stocks becomes an important issue over the last two decades. Usually fleet size, GRT, LOA, hold capacity, or other nominal effort metrics are required in support of providing advice related to fishing capacity management measures. Considering the availability of the information about the characteristics of vessels, FAO and tuna RFMOs encourage every fishing country should taking the responsibility to measuring its own fishing capacity. Data Envelopment Analysis (DEA) approach is proposed as a useful approach for assessing capacity in fisheries. In this study, different measures of capacity and capacity utilization (CU) are estimated for the Taiwanese longline fishery operated in the Atlantic Ocean. From 2003 to 2005, the average potential fishing capacity for bigeye of boat target on bigeye was estimated to be between 176 and 278 mt. The average potential fishing capacity for albacore of boat target on bigeye was estimated to be between 1 and 3 mt. The average potential fishing capacity for bigeye of boat target on albacore was estimated to be between 3 and 50 mt. The average potential fishing capacity for albacore of boat target on albacore was estimated to be between 173 and 389 mt. |
