Abstract

This study aims to analyze the effect of fishing ground differences between WPPNRI 711 and 712 on squid (Loligo spp) catches using boat-operated falling nets landed at Nusantara Fishing Port Muara Angke, Jakarta. The research employed a quantitative approach with a two-treatment experimental design, involving fishing operations in two different areas with an equal number of trips (six trips each), analyzed using an independent samples t-test. The results indicated no statistically significant difference in catches between WPPNRI 711 and 712 (p = 0.747 > 0.05). However, production data revealed variations in catch differences, with CPUE (Catch Per Unit Effort) in WPP 711 being higher than in WPP 712. These variations are likely influenced by environmental factors, oceanographic conditions, fishing pressure, and squid spawning seasons. The implications of this study highlight that differences in fishing grounds do not always produce significant statistical impacts on catches but remain crucial for sustainable squid fisheries management. Policy recommendations include regulating fishing efforts based on spawning seasons, routine stock monitoring through CPUE, and adopting advanced fishing technologies to enhance efficiency and sustainability. This research provides valuable input for fisheries management and supports sustainable utilization of squid resources at Muara Angke.

Abstract

Ekas Bay has very rich fishing potential, especially for the red snapper species (Lutjanus spp.). This study aims to determine the effect of mesh size of gill nets on catch and determine the mesh size that is more effective for catching Red Snapper (Lutjanus spp.) measures above 300 grams in the waters of Ekas Bay, East Lombok. This research was carried out in the waters of Ekas Bay, East Lombok from June to August 2025. This research method uses an experimental method that distinguishes three treatments with nine replications, using a Group Random Design (RAK). The data collection techniques in this study are observation, active participation, and interviews. Then analyzed using multiple fingerprint analysis (ANOVA). If the effect is real or very real, the effect can be seen by using the smallest real difference test (BNT), after that the BNT value is compared to the average value of the treatment. The results of the study showed that the use of different mesh sizes had a very real effect on the catch of red snapper. The 4-inch mesh proved to be the most effective with 65% of the fish caught being ≥300 grams in size, while the 3-inch mesh was 30% and the 2-inch mesh was only 5%. Thus, the use of larger mesh can increase selectivity for adult fish while reducing juvenile catches.

Abstract

Denpasar is a major fisheries hub in Bali, with Benoa Harbor serving as a docking site for large fishing vessels. The decline in catch volume and annual production has increased the urgency of implementing environmentally friendly fishing and resource management practices. Fishers in Serangan continue to use handline fishing gear, prompting the need for research to assess its environmental friendliness. This study employed a survey method, collecting data through field observations, interviews, and questionnaires. The analysis was conducted based on nine criteria of the Code of Conduct for Responsible Fisheries (CCRF) with a sample of 30 respondents. The results show that handline fishing has high selectivity, targets octopus (Octopus sp) as the main catch, and has minimal impact on habitats and biodiversity. The lowest score was recorded in the criterion of minimum discarded catch due to the presence of bycatch such as skipjack tuna (Katsuwonus pelamis) and giant trevally (Caranx ignobilis), although these species still have market value. The total score obtained was 32.83, placing handline fishing in the highly environmentally friendly category.

Abstract

Indonesia is a large archipelagic country with significant fisheries potential. However, fish resources in Indonesian waters have shown a declining trend over the past decade. This decline is caused by various factors, including the deterioration of coastal environmental quality due to human activities that pollute the sea, destructive fishing practices, and excessive exploitation or overfishing. This study aims to analyze the utilization rate of bigeye tuna in FMA-NRI 573 landed at PPS Nizam Zachman and to provide recommendations for the utilization efforts of bigeye tuna in FMA-NRI 573 landed at PPS Nizam Zachman. The utilization rate of fish can be calculated by comparing the total catch to the maxmimum sustainable yield (CMSY) using the formula TPc=(Ci/CMSY)×100%TP_c = (C_i / C_{MSY}) \times 100\%TPc=(Ci/CMSY)×100%. The utilization rate obtained, with an average CMSY of 846,325, falls under the category of Lightly Exploited according to FAO and Moderately Exploited based on Ministerial Regulation KP No. 22/2021. This indicates that the utilization is still relatively low or minimal. Therefore, it is necessary to conduct a review of existing fishing regulations in order to maintain the potential sustainability of capture fisheries.
