چکیده
The technical efficiency and the capacity utilization of purse seine fisheries in North Sulawesi, Indonesia, were assessed by employing peak-to-peak and Data Envelopment Analysis (DEA) methods. The method gauged the efficiency of fishing gear utilization by comparing the level of input utilization to the generated output. This study used an approach that focused on both input and output approaches. The findings showed an annual increase of approximately 6.7 in the number of purse seiners' cruises, but this did not translate into an increase in the catch per unit of effort. The purse seine fisheries at Tumumpa Coastal Fishing Port experienced excessive capacity utilization for a long period (from 2006 to 2020). It was essential to reduce fishing activities by an average of 54% from 2010 to 2020 to ensure exploitation at the optimum fishing capacity. We averagely computed the efficiency values for vessels with gross tonnages (GT) of less than 30 and greater than 30, respectively. It is imperative to reduce the fishing effort (number of cruises and fishing days), as these values deviated significantly from the optimal value.
