Status Keberlanjutan Penangkapan Sumberdaya Ikan Layang (Decapterus Sp.) dengan Menggunakan Alat Tangkap Purse Seine di Pelabuhan Perikanan Samudera Belawan Provinsi Sumatera Utara

Abstract

Layang fish (Decapterus sp.) is one of the most common species caught at PPS Belawan. The purpose of this study was to determine the value of Catch Per Unit Effort (CPUE) and maximum sustainable yield (MSY) in 2017-2021 using Purse Seine fishing gear at Belawan Ocean Fishing Port and to determine the sustainability status of kite fish based on ecological, economic, technological, social and institutional dimensions at Belawan Ocean Fishing Port. This research was conducted from October to November 2022. The methods used were CPUE, Chlorophyll Concentration, Sea Surface Temperature and Sustainability Status using the Rapfish Application. The results showed that the highest CPUE value was in 2020 at 2,30 tons/trip while the lowest CPUE value was in 2019 at 0,88 tons/trip, the maximum sustainable potential value was 11.906,99 tons/trip while the optimum fishing effort value was 13.382,74 trips/year. The sustainability status of swallowfish resources (Decapterus sp.) in the Belawan Ocean Fishing Port, namely the ecological dimension of 48.15% is in the less sustainable category while the economic dimension is 65,13%, technology is 67,52%, social is 56,25% and institutional is 64,87% included in the fairly sustainable category.
