Abstract

Indonesia Fisheries Management Area 718 (IFMA-718), located in the Arafura Sea, is known for its high marine biodiversity and serves as a strategic fishing ground. However, the lack of fishing gear selectivity in this area poses a significant threat to the sustainability of marine resources. This study aims to evaluate the selectivity of purse seine fishing gear through biodiversity analysis using the Shannon-Wiener diversity index (H’), evenness index (E), and dominance index (C). Data collection was conducted from September 2023 to March 2024 in the Arafura Sea using a 149 GT purse seiner. Catch data were categorized into target species, bycatch, and discards. The results showed that the values of H’ ranged from 0.77 to 1.40, E values were mostly greater than 1, and C values were below 0.5. These findings indicate a high species diversity and evenness, alongside low dominance, suggesting a relatively balanced community structure. However, such diversity also reflects the low selectivity of the fishing gear, which captures both target and non-target species, including demersal and benthic organisms. In conclusion, the purse seine gear used in IFMA-718 is considered to have low selectivity and is potentially harmful to non-target marine ecosystems. This study provides essential insights for improving selective fishing practices and implementing sustainable fisheries management in the region.

Abstract

Purse seine is a widely used fishing gear in Indonesia for capturing small schooling pelagic species. The study aimed to analyze the catch composition of purse seine fishing performed using the KM Bintang Mas Maritime based at Nusantara Fisheries Port (NFP) Pekalongan and fishing in Indonesia Fisheries Management Area (IFMA 713) Sulawesi Sea. Data was collected through fishing trips observations and catch documentation from September 12, 2023 to February 16, 2024. The total catch was 155,000 kg which was composed of three dominant target species: Decapterus macarellus (32.25%), D. punctatus (29.03%), and Sardinella lemuru (22.59%) which make up 83.87% of the total catch. Bycatch made up 16.13% and included Euthynnus affinis, Rastrelliger kanagurta, Selar crumenophthalmus, and Priacanthus macracanthus. The high proportions of small pelagic fish in the catch is indicative of purse seine selectivity and show the target stocks in IFMA 713 are available. This data highlights the significance of regular evaluation and dynamic management strategies that can adapt to evolving conditions to maintain ecological balance and enduring resources.
