Abstract

The uncontrolled fishing of skipjack tuna (Katsuwonus pelamis) without recruitment efforts has led to stock degradation and unstable abundance due to excessive pressure. This study aims to estimate the sustainable potential of skipjack tuna by calculating Catch per Unit Effort (CPUE), assessing Maximum Sustainable Yield (MSY), and determining Total Allowable Catch (TAC). The research was conducted at PPN Sibolga and utilized survey-based data collection and surplus production analysis using the Schaefer model. The findings indicate that standardized CPUE in 2018 was 0.639 tons/trip, increased to 0.764 tons/trip in 2019, dropped to 0.527 tons/trip in 2020 and 0.506 tons/trip in 2021, and returned to 0.639 tons/trip in 2022. Purse seines were identified as the primary fishing gear. The Schaefer model estimated CMSY at 8,699.7 tons, classifying the fishery as fully exploited. FMSY was calculated at 5,447 trips, with annual efforts consistently exceeding this threshold, indicating overfishing. The TAC was set at 6,959.7 tons. Management strategies should regulate fishing efforts, enforce gear specifications, and implement science-based fisheries policies to prevent further degradation. Aligning fishing activities with sustainable thresholds will support skipjack tuna stocks' recovery and long-term productivity. These findings underline the importance of adaptive management and collaboration to sustain marine ecosystems and protect livelihoods

Abstract

Program pengabdian masyarakat ini bertujuan meningkatkan kapasitas nelayan Kota Sibolga dalam pencatatan hasil tangkapan ikan pelagis untuk mendukung pengelolaan perikanan berkelanjutan. Kegiatan ini melibatkan 30 nelayan dengan pendekatan partisipatif melalui penyuluhan, praktik lapangan, pendampingan, dan evaluasi. Hasilnya, 90% peserta memahami pentingnya pencatatan setelah pelatihan, dan 85% konsisten mencatat hasil tangkapan selama pendampingan. Solusi berupa aplikasi offline diperkenalkan untuk mengatasi kendala sinyal di laut, sementara logbook manual menjadi alternatif bagi nelayan yang belum terbiasa dengan teknologi. Data hasil tangkapan yang terkumpul membantu nelayan memahami pola tangkapan musiman dan menjadi dasar bagi pemerintah untuk menyusun kebijakan seperti kuota tangkapan dan larangan penangkapan musiman. Program ini menunjukkan bahwa kolaborasi lintas sektor dan pendekatan berbasis komunitas efektif dalam meningkatkan kapasitas nelayan sekaligus mendukung kebijakan berbasis data. Dengan keberlanjutan program ini, diharapkan pengelolaan perikanan di Sibolga dapat menjadi model perikanan berkelanjutan di Indonesia.

Abstract

This study aims to analyze the catch composition and evaluate the financial feasibility of using senangin gill nets at the Fisheries Port Technical Implementation Unit (UPT) in Riau Province. Primary data were collected through direct observation and interviews with boat-owning fishermen, while secondary data were obtained from relevant institutions. The results indicated that senangin fish (Eleutheronema tetradactylum) was the main catch with the highest CPUE values during the 2020–2023 period. The by-catch included mullet (Mugil cephalus), pomfret (Pampus argenteus), and catfish (Arius thalassinus). The financial feasibility analysis showed that the fishing operation is viable, with a positive Net Present Value (NPV), an Internal Rate of Return (IRR) exceeding the discount rate, a Payback Period (PP) of less than five years, and a Benefit-Cost Ratio (BCR) greater than one. Therefore, the use of senangin nets is considered ecologically sustainable and economically beneficial for local fishermen.
