【 摘 要 】

High fishing gear productivity can increase exploitation so that it can endanger the sustainability of resources. This study aimed to examine and find the best estimated model for the status of utilization. Next analysis are assess the level of degradation and depreciation of Skipjack tuna in the North Coast of Aceh (NCA). It conducted using vary methods on analyzing this problem. The methods are using both interview and bio economic Gordon Schaefer model. On bio economic analysis were using Fox Algorithm, Clark Yoshimoto Pooley, Walter Hilborn, and Schnute estimated model. Its result then compared to find best estimated model for the status of utilization Skipjack resources at NCA. The result shows Fox Algorithm has the best estimation model based on suitability on the field and statistical parameter. The highest production on MSY management regime is 3,348 tons per year and MEY management regimes shows maximum value at Rp.40.304 billion per year. Actual Effort are overfished both biologically and economically compared with optimal effort and sustainability effort. Actual Effort reach 8,618 trips per year while the optimal effort for sustainability is 8,039 trips per year and the economic optimum effort is 6.166 trips per year. The average magnitude of the rate coefficient values on degradation is 0.24 and depreciation Skipjack fish resources is 0.44. It means pelagic fish resources at NCA has not been at the level of degraded and depreciated.
