Long fishing is an environmentally friendly traditional fishing tool that is commonly used by fishermen to catch fish passively using bait, both in sandy waters and in coral reef areas. Grouper fish (Epinephelus sp.) tend to inhabit waters of a certain depth, especially in areas of coral fractures and dead corals that serve as shelter and foraging. Determining the right depth setting in the operation of a fishing rod is essential to optimize the catch. This study aims to determine the effect of the difference in setting depth on grouper fish catch in the waters of Pengambengan Beach and determine the most effective depth. The study used an experimental method with three depth treatments, namely 10 m, 15 m, and 20 m, each repeated nine times. Data analysis was carried out by Group Random Design (RAK) and ANOVA test. The results showed that a depth of 10 m produced the highest catch with a total of 35 fish (average 3.89 fish/trip), followed by a depth of 15 m with 10 fish (average 1.11 fish/trip), and a depth of 20 m with 7 fish (average 0.78 fish/trip). Statistically, the difference in depth has a real influence on the number of grouper catches. A depth of 10 m is recommended as the optimal setting for the operation of long fishing rods in the waters of Pengambengan Beach.

Swanggi fish (Prianchantus tayenus) is one of the important commodities that are widely caught at the Perikanan Nusantara Port (PPN) Brondong, Lamongan, East Java. Increased fishing acivity is feared to cause excessive pressure on fishery resources that could potentially cause overfishing. This study aims to analyze the level and status of swanggi fish utilization. The method used in this research is descriptive quantitative with a fox production surplus model approach to calculate Maximum Sustainable Yield (MSY), Totl Allowable Catch (TAC), and utilization rate. The data analyzed were the catch abd effort of swanggi fishing from 2015 to 2024. The result showed that the Maximum Sustainable Yield (MSY) value of Swanggi fish was 14,486,042 kg/year with an optimum effort F MSY of 11,689 trips/catch and TAC of 11,588,833 kg. the utilization rate of swanggi fish during 2015 to 2024 reached 105%. The value of the utilization status of swanggi fish is 85% which can be categorized that the exploitation of swanggi fish resources is Full Exploited. Therefore, sustainable fisheries management is needed through effort limitation and gear evaluation to maintain the sustainability of swanggi fish resources in PPN Brondong.

The utilization of Bouke Ami fishing gear in Indonesian waters, particularly in PPN Muara Angke, plays a significant role in managing fishery resources and increasing production. This gear is commonly used by fishermen to catch pelagic fish such as mackerel, tuna, and squid. However, the environmental friendliness of Bouke Ami fishing gear is crucial for sustainable fisheries management. While effective in catching fish, this fishing gear can negatively impact the marine ecosystem, including damage to coral reefs and the capture of juvenile fish, which affects their growth. This research aims to assess the level of environmental friendliness of the Bouke Ami fishing gear used in PPN Muara Angke. Conducted from November 2025 to January 2026, the study employed a descriptive method, using interviews and questionnaires with Bouke Ami fishermen. The findings are expected to contribute to the literature on sustainable fisheries and highlight the importance of using environmentally friendly fishing gear, in line with the Code of Conduct for Responsible Fisheries.

In conclusion, pellets are the most effective type of bait to use in the anco net fishing gear in catching larval shrimp at the research location.

In Indonesia, maritime safety remains a problem. Ship captains and ship owners often disregard maritime safety standards, particularly for fishing vessels. Provisions for criminal liability for domestic fishing vessels that fail to meet maritime safety standards are an important legal instrument for regulating and enforcing maritime safety regulations in the fisheries sector. Failure of vessels to comply with safety requirements, such as the completeness of safety equipment, engine condition, and vessel structure, can potentially lead to accidents that endanger the lives of crew members and negatively impact the marine environment. This study uses a normative research method with a legislative approach. This article focuses on examining aspects of criminal liability, including the subjects, objects, and legal sanctions imposed for violations of maritime safety standards. The results indicate that perpetrators of violations can be subject to criminal sanctions in the form of fines, detention, and even revocation of vessel operating permits, taking into account human rights and environmental protection. Effective and synergistic law enforcement between relevant authorities is essential to provide a deterrent effect, encourage compliance with safety standards, and improve the system for the sustainability of marine resources.

This Community Service activity aims to foster a spirit of mutual cooperation and to assist local fishermen engaged in seaweed businesses in the processing and cleaning of their harvests in the Amal Beach Area, East Tarakan District. Seaweed harvested from the sea needs to undergo a thorough cleaning process to maintain its quality, ensure market readiness, and meet industry standards. The activity was carried out by six implementers who collaborated directly with the local fishermen through mutual cooperation, seaweed cleaning, and education on environmentally friendly sea product management. The implementation methods included field observation, guidance, and hands-on practice at the fishermen’s business locations to provide practical understanding. The results indicated improved efficiency in the seaweed processing chain, from cleaning to storage, thereby reducing the risk of damage and quality loss. Additionally, the fishermen’s awareness of the importance of maintaining cleanliness and the balance of coastal ecosystems increased significantly. This activity also strengthened social bonds between students and the fishing community, fostering harmonious communication, and instilling values of togetherness, environmental care, and social responsibility. The positive impact of this program is expected to serve as a sustainable model for sea product management while promoting a collaborative culture between academics and coastal communities.

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.

The Indonesian government has been actively combating illegal fishing practices at sea because they harm the country and reduce fish populations. However, attention to freshwater fisheries, especially endemic fish, is still limited. In fact, endemic fish play an important role in aquatic ecosystems and local culture. Fish resource conservation aims to protect, preserve, and utilize fish and their ecosystems and genetic diversity so that their existence and availability remain sustainable. The diversity of freshwater fish in Indonesia faces serious threats from human activities. The main factor is the introduction of new species that grow uncontrollably, becoming pests and harming ecosystems and communities. In addition, overfishing and declining habitat quality further exacerbate the situation. These threats pose a risk of extinction for endemic fish. Therefore, conservation efforts need to be strengthened to maintain ecosystem balance and support the livelihoods of communities that depend on fish farming. Legal protection is an important aspect in addressing this issue. Law No. 31 of 2004 concerning Fisheries and Law No. 5 of 1990 concerning Conservation of Living Natural Resources and Ecosystems have provided a legal basis for fish resource management. However, their implementation and enforcement remain weak. This study uses a normative juridical approach with secondary legal materials, emphasizing the importance of improving the legal framework and more effective governance. Measurable, transparent, and sustainable conservation measures are needed to ensure the optimal utilization of fish resources. Thus, the sustainability of freshwater ecosystems and the welfare of communities that depend on endemic fish can be guaranteed.

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.

This study aims to describe the implementation of the Community Economic Empowerment Program in the coastal area of Samber Village, Yendidori District, Biak Numfor Regency through the Kalamo Program (Modern Fishermen's Village). The approach used is qualitative descriptive with data collection techniques through in-depth interviews, observations, and documentation. The results of the study show that the implementation of the Kalamo Program has had a positive impact on the coastal community of Samber Village. In terms of improving skills and institutional access, it can be seen that there is training and the formation of cooperatives, although the management still needs to be improved. In terms of natural resource management, some communities have begun to implement more environmentally friendly fishing practices. Meanwhile, the improvement of the quality of life of the community can be seen from the increase in income and the emergence of new business opportunities, although it is not evenly distributed among all fishermen groups. Overall, the implementation of this program has been running, but it is not fully optimal. Further efforts are needed to strengthen institutional capacity, equitable program distribution, and increase socialization so that the empowerment goals can be achieved comprehensively.

Identifying fish species found in the Sendang Seruni stream, Tamansari Village, Licin District, Banyuwangi Regency, and analyzing the diversity and quality of its waters. Sampling was conducted over 14 days in July 2025 using umbrella traps, fishing rods, and underwater camera observations at three observation stations. The results of the study showed that there were six fish species, namely Rasbora lateristriata (Wader Pari), Barbodes binotatus (Wader Cakul), Oreochromis niloticus (Nila), Gambusia affinis (Cere), Nemacheilus fasciatus (Uceng), and Channa striata (Channa). The most abundant species was Wader Pari (25 individuals), while Channa was only one individual. Fish diversity in Sendang Seruni was classified as low with an H' value of 1. Clean, stable, and oxygen-rich water quality supports the existence of sensitive species such as B. binotatus, while polluted waters tend to be dominated by tolerant species. These results indicate the need for habitat management and conservation efforts to maintain the balance of the Sendang Seruni aquatic ecosystem. 

Bluru Kidul Village is an area located near the northeastern coast of Sidoarjo, where its geographical position provides significant benefits for the community. Consequently, the majority of residents work as fishermen and live side by side with the marine ecosystem. Due to the existence of Bluru Kidul Village, Sidoarjo City is often referred to as a fisheries or coastal city. The fish resources in these waters are dominated by small pelagic fish, large pelagic fish, and demersal fish. One of the most widely used fishing gears is the gill net. This study applied treatments with soaking durations of 2 hours, 3 hours, and 4 hours. The objectives of this research were to identify the composition of gill net catches, analyze the effect of different soaking times on gill net catches, and determine the optimal soaking duration for catching Indian mackerel (Rastrelliger) using gill nets. Data analysis was conducted using statistical methods, including analysis of variance (ANOVA) and normality tests to ensure data suitability. To determine whether soaking duration had a significant effect, a further statistical test, namely the Least Significant Difference (LSD) test, was applied to identify which soaking time produced the best catch of Indian mackerel. The results indicated that there were significant differences in catch variables between the 4-hour treatment and the 3-hour and 2-hour treatments, whereas the difference between the 3-hour and 2-hour treatments was not significant. This finding demonstrates that the 4-hour soaking duration resulted in significantly different catch outcomes compared to the 3-hour and 2-hour durations, but no significant difference was observed between the 3-hour and 2-hour treatments.

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.

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.

Capture fisheries are an important economic sector in the coastal area of ​​Depok Beach, Yogyakarta Special Region. Fishing activities in this area use various fishing gear, one of which is the bottom gill net. However, the use of this fishing gear can have negative impacts on the aquatic environment and marine ecosystem, such as the decline in the population of white pomfret and ribbonhead fish, which are the main catch. This study aims to analyze the level of environmental friendliness of the use of bottom gill nets in Depok Beach using a descriptive quantitative approach. The methods used in this study include direct surveys of fishermen, observation of fishing operations, and analysis of catch results. Data were collected through a questionnaire containing 9 indicators compiled by the FAO, which cover aspects of gear selectivity, impact on aquatic habitats, fisherman safety, catch quality, and social acceptance of the fishing gear. The results showed that bottom gill nets had the lowest level of selectivity with a score of 1.13, indicating that this tool is less selective in selecting the types of fish caught. However, the indicator regarding consumer safety received the highest score of 4.00. Overall, the test results show that the use of bottom gill nets at Depok Beach has an environmental friendliness score of 27.06, which indicates that this fishing gear is classified as environmentally friendly even though it needs improvement in terms of selectivity.

Capture fisheries are one of the most contributing sectors in producing fishery products.The fourfinger threadfin (Eleutheronema tetradactylum) is one of the key commodities in the capture fisheries sector of Pasuruan City. The catch yield of this species is influenced by the mesh size of the gillnet used. This study aimed to determine the effect of different mesh sizes on the catch yield of fourfinger threadfin and to identify the most effective mesh size. The research was conducted using an experimental fishing method with a Randomized Block Design (RBD) comprising three gillnet mesh size treatments: 1.75 inches, 2.5 inches, and 4 inches, with nine fishing trips. Data on catch weight and number were analyzed using a One-Way ANOVA followed by the Least Significant Difference (LSD) test. The ANOVA results showed an F-value of 10.083 with a significance level of 0.001 (p-value < 0.05), indicating a significant difference in the catch weight of fourfinger threadfin (Eleutheronema tetradactylum) among the mesh size treatments. This finding suggests that mesh size has a significant effect on catch weight, with the 2.5-inch mesh size being the most effective for catching fourfinger threadfin in the Madura Strait, as it produced the optimal catch weight compared to 1.75-inch and 4-inch mesh sizes.

Panggungrejo District in Pasuruan City is a central hub for fishing activities with significant potential for capture fisheries production. One of the fishing gears used by fishermen in this area is the boat dredge, which is classified as an active fishing gear. This study aims to assess the environmental friendliness of the boat dredge used by fishermen in Panggungrejo based on the principles of the Code of Conduct for Responsible Fisheries (CCRF). The research employs a descriptive method, using data collection techniques such as interviews with structured questionnaires, direct observations, document analysis, and literature review. The study involved 32 respondents consisting of fishermen using the boat dredge. Data analysis was performed by assigning scores based on the principles outlined in the CCRF that are related to sustainability and environmental impact of the fishing gear. The results showed that the boat dredge in Panggungrejo scored a total of 855, with an environmental friendliness score of 26.71. Based on this score, the boat dredge falls into category III, considered “environmentally friendly.” However, several indicators related to resource efficiency and the impact on aquatic ecosystems still need improvement to further enhance the environmental friendliness of this fishing gear. This study provides recommendations for the development and improvement of more environmentally friendly fishing techniques and increasing fishermen’s awareness of sustainability in fisheries practices.
