Abstract

The high fishing activity targeting kawakawa (Euthynnus affinis) at the Kejawanan Fishing Port has the potential to increase pressure on the sustainability of fish resources. This study aimed to analyze the sustainable potential, determine the Maximum Sustainable Yield (MSY) and Total Allowable Catch (TAC), and analyze the exploitation level of kawakawa resources at Kejawanan Fishing Port. The study employed a survey method with a descriptive quantitative approach. Catch and fishing effort data from 2014–2024 were analyzed. The analysis included fishing gear standardization using the Fishing Power Index (FPI), Catch Per Unit Effort (CPUE) calculation, and sustainable potential estimation using the Schaefer and Fox surplus production models. The results showed that cast net had the highest productivity and was therefore selected as the standard fishing gear. The Fox model estimated an MSY of 76.87 tons/year with an optimum fishing effort of 210.97 trips/year. The estimated TAC was 61.50 tons/year, with an allowable fishing effort of 116.67 trips/year. The exploitation level reached 356.81%, indicating that kawakawa resources at Kejawanan Fishing Port were in an overexploited condition. Therefore, fishing effort and catch should be controlled to maintain the sustainability of kawakawa resources at Kejawanan Fishing Port.
