Bioeconomic analysis of Savalai Hairtail (Lepturacanthus savala) catches that landed at coastal fishing port (PPP) Sadeng, Indonesia

Savalai hairtail (Lepturacanthus savala) is one of the quite important commodities and has been widely utilized. In the peak season, L. savala is very abundant. L. savala becomes an export commodity, with demand from several Asian countries, including Korea, Japan and other neighboring countries. Export demand reaches 100-500 tons/month. This condition causes L. savala fisheries to have quite large opportunities in the international market. The research was conducted from March 20 to May 30, 2024, which took place at the Coastal Fishery Port (PPP) Sadeng. The method used was convenience sampling of fishermen with approximately 10 L. savala fishing vessels at PPP Sadeng. The purpose of the study was to analyze the Maximum Sustainable Yield (MSY) and Analyze the Maximum Economic Yield (MEY), Open Access Equilibrium (OAE), and determine the level of utilization status of L. savala resources at PPP Sadeng Port. Based on the CPUE analysis, the average standard CPUE value of L. savala is 1.612 kg/unit. The CPUE value from 2015 to 2020 fluctuated. From the results of the Gordon-Schaefer bioeconomic analysis model, the MSY value achieved by the L. savala capture fishery business was 4.073 kg/year with an EMSY of 299 units/year. The CMEY value achieved by the L. savala fishing business was 3.660 kg/year with an EMEY of 204 units/year and a MEY profit of IDR 75,389,065 per year. The COAE value achieved by the L. savala fishing business was 3537.431494 kg/year with an EOAE of 407.2252349 units per year. And the advantage of the OAE Analysis value of IDR 0 indicates that the level of effort on L. savala resources in Sadeng is on average less than 100% or still safe in terms of resources and fishing economy in fishing areas in Sadeng waters. This happens because fishing efforts carried out by fishermen are still considered less than maximizing the potential in the field of L. savala fishing every year.
