Abstract

Open-access fishery resources encourage fishing competition that can cause stock decreases and overfishing; therefore, bioeconomic management based on sustainability potential and utilization rate assessments is needed to maintain sustainability. This research aims to determine anchovies' potential and utilization rate (Stolephorus sp) at the UPTD Fishery Port Region I, Carocok Tarusan, West Sumatra Province. The research was conducted in December 2024 using secondary data in the form of annual catch and fishing effort for 2016-2023, obtained from relevant institutions. The methods used were the Catch Per Unit Effort (CPUE) and surplus production models of Schaefer and Fox. Based on the results of the analysis, the Schaefer surplus production model was the most appropriate model for analyzing the potential of anchovies at the Carocok Tarusan Fishing Port. This model estimates MSY at 445,211.65 kg/year with an optimum effort of 6,547 trips/year. JTB is estimated at 356,169.32 kg/year. During the research period, the average utilization rate of anchovies reached 54%, showing that fish stocks were in a moderate state. This means anchovy resources have not been overexploited and can still be utilized optimally. The exploitation rate of 33% indicates that there are still opportunities to increase fishing efforts while continuing to apply the principles of sustainable management.

Abstract

The utilization of Indian scad (Decapterus russelli) in Carocok Tarusan has made an important contribution to fishing activities, but data on the potential and rate of utilization are limited. The research aims to determine the potential and level of utilization of indian scad (Decapterus russelli) landed at UPTD Fishery Port Region I, Carocok Tarusan, West Sumatra Province. The research was conducted in December 2024 using secondary data from the institution on catch and fishing efforts for 2019-2023. Methods used are Catch Per Unit Effort (CPUE) and surplus production models of Schaefer and Fox to estimate the maximum sustainable yield (MSY) and optimum fishing effort (f-optimum). According to the analysis results, the Fox model is the most suitable model to describe the stock status and management of indian scad in this region. MSY was estimated at 234,653.74 kg/year with an optimum effort of 1,902 trips/year. Total allowable Catch (TAC) was 187,722.99 kg/year. The average utilization rate was 97%, which shows that the Indian scad stock is fully exploited. Meanwhile, the average level of effort at 110% showing that fishing effort exceeds the optimum level, meaning that more careful management is needed to ensure the sustainability of the stock
