Abstract

This study was conducted to determine the effect of vitamin C supplementation on the survival rate and histopathological changes of gills and kidneys of tilapia infected by Aeromonas hydrophila. Three doses of vitamin C were tested (150; 300; and 450 mg/kg) with two control groups. Tilapia with uniform size (average weight of 14 grams) as the criteria for inclusion were randomly distributed in five ponds with 15 tilapia fish per ponds. Tilapia was fed with hands until full for two weeks. Tilapia was then infected with A. hydrophila to find out the survival rate and histopathological changes of gills and kidneys at the end of the experimental period or 7 days after infection. The supplementation of 150 mg/kg vitamin C in feed increased the survival rate (%) in Tilapia by 86.67% or higher than other treatment and control groups. The damage to gills in terms of lamella separation was found in all treatment groups, as well as kidneys. The results found that the supplementation of 150 mg/kg vitamin C in feed increased survival rate but did not give effective protection on gills and kidneys.

Abstract

Fishermen are an essential group in supporting national food security; however, their lives are still characterized by various social and economic challenges, such as unstable income, low education levels, and high household expenditure burdens. This research aims to provide an overview of the socio-economic conditions and welfare of Bouke Ami fishermen in the Nusantara Fisheries Port (PPN) Muara Angke, North Jakarta, through the Fishermen’s Exchange Rate (NTN) and Fishermen’s Exchange Rate Index (iNTN). The study was conducted in May–June 2025 using a descriptive method with quantitative and qualitative approaches. Data collection techniques included observation, interviews, and questionnaires distributed to 100 Bouke Ami crew members (ABK). The results showed that the majority of crew members were aged 30–39 years, had completed only junior high school education, received health services through community health centers (puskesmas), had three family dependents, and most lived in their own homes. The average total monthly income of Rp5.733.500 is considered high as it exceeds the 2025 DKI Jakarta minimum wage (UMP) of Rp5.367.381. Meanwhile, the average total expenditure of Rp5.396.761 remains below income, indicating manageable household finances. The NTN value was 1,06 in April and 1,07 in May, resulting in an iNTN of 101%, indicating that Bouke Ami fishermen in PPN Muara Angke, North Jakarta, are at a level of economic welfare classified as prosperous with slight improvement. This increase reflects a modest rise in fishermen’s purchasing power between the two months and can serve as basis for formulating policies aimed at empowering coastal fishermen.

Abstract

Regulation of the Minister of Maritime Affairs and Fisheries number 56 of 2014 and Regulation of the Minister of Maritime Affairs and Fisheries number 10 of 2015 help realize responsible fisheries management and combat Illegal, Unreported, and Unregulated (IUU) Fishing in Fisheries Management Area of ​​the Republic of Indonesia (WPP NRI). The policy of temporarily stopping permits (moratorium) for ships manufactured overseas (ex-foreign vessels) directly impacts fishermen working on ex-foreign vessels in the form of reduced income to loss of livelihoods. The research used a retrospective approach where policy analysis is carried out on the consequences of a policy after the policy is implemented. It is usually referred to as an evaluative analysis model, so it is expected to produce information that can improve the quality of the policies implemented by the government. The study aimed to determine the moratorium's impact on capture fisheries licensing on business activities, especially on fishing effort, catch per unit effort (CPUE), and socioeconomic conditions of fisheries at Benoa Harbor, Bali. This research was conducted from March to October 2022 in the Benoa Harbor Area, Bali. The data in this study were obtained from observation, interviews, questionnaires, and literature/document studies. The moratorium policy for ex-foreign vessels, followed by a ban on transshipment, significantly changed the pattern of trade, particularly for tuna, which was dominated initially by fresh tuna to frozen tuna with a lower value. The longline catches are dominated by Thunnus alalunga, followed by Thunnus maccoyii, Thunnus albacares, and Thunnus obesus. The total of ships in 2014 was 915 units, and only 246 ships remained in 2018. The significant decrease in fish landings in 2015-2017 is a real impact of the moratorium on ex-foreigners in Benoa. The results of the data analysis show that in 2014 the number of attempts was 2,264, which continued to decline until 2018, with only 697 trips.

Abstract

Benoa Port has fishing vessel activities that are the foundation of Bali's tuna swamp fisheries (longlines). Sustainable tuna capture fisheries will be impossible to attain if the number of infractions in the marine and fisheries sectors continues to rise. The government's efforts to reduce infractions in marine and fisheries are achieved through tightening the oversight system. The Vessel Monitoring System (VMS) surveillance system was created to reduce breaches in the marine and fishery sectors. The goal of this study is to determine the monitoring and suspected indication of violations of longlines using the VMS at the Benoa PSDKP as well as to learn about the capture fisheries management strategy using VMS data on longlines at Benoa Port using an analytic hierarchy process (AHP) approach. This study used a qualitative-quantitative descriptive technique with AHP analysis to determine the value of the management priority scale. Based on the findings of monitoring longlines with web tracks from January to December 2022, the most targeted fishing area was the Indian Ocean High Seas, and the most prominent suspected indication of violation was the inactivity of VMS when the vessel was operating. The main approach for managing capture fisheries utilizing VMS data on longlines in Benoa Port with the AHP analysis is for the government to offer subsidies for installing VMS on all fishing vessels, particularly those under 30 GT.

Abstract

Echinoderms are key ecological organisms that play a protective role in balancing the marine ecosystem by breaking down trash or leftover organic material that is not used by other species. Echinoderms are marine biota that are sensitive to changes in water characteristics, so they can be used as bioindicators. Echinoderm habitats can be found in all marine ecosystems, but the highest diversity is found in intertidal areas, which are easily affected by land activity. One of the intertidal areas that is often used by humans is the Bay Area. This research aims to find out the types of echinoderms and analyze the community structure of echinoderms in Pegametan Bay, Bali. The research was carried out using the method of line transect at 18 points for data on the number and types of echinoderms in depth 1x1 m quadrat transect. Based on the observations, it was found that there are 3 classes of echinoderms that live on Bingin Beach (Echinoidea, Asteroidea, and Holothuroidea) with 3 orders, namely Diadematoida, Valvatida, and Holothuriida. The most commonly found species is D. setosum from the Echinoidea class. The structure of the echinoderm community in Pegametan Bay is shown by an average density value of 12.60 ind/m² with a diversity index value of 0.46, which is classified as low diversity; a uniformity index value of 0.36, which is relatively low; and a dominance index of 0.73, which is relatively high. Based on the results obtained, it can be concluded that the diversity index in Pegametan Bay is low, the evenness index is relatively low, and the dominance index is high. The values of temperature, pH, dissolved oxygen (DO), and salinity are still within the standard limits for marine biota.

Abstract

The capture fisheries landed at the Nusantara Fishing Port (PPN) in Prigi, Trenggalek, East Java, play a strategic role in influencing the social and economic conditions of fishing households. The production of bullet tuna is highly volatile, which in turn impacts these socio-economic conditions. This study aims to analyze the assessment of the social and economic domains in the implementation of EAFM for the bullet tuna fishery at PPN Prigi. It employs a qualitative method using the Ecosystem Approach to Fisheries Management (EAFM), which integrates social and economic aspects as a potential solution to achieve sustainable fisheries management and improve fishers' welfare. Data collection techniques included field observations and interviews with 98 fishers who use purse seine and Danish seine gear. The findings indicate that the social domain is rated as 'good' with a composite score of 66. This rating is characterized by a low potential for conflict, which is crucial to maintain, although stakeholder participation and the utilization of local knowledge are not yet optimal. The economic domain was classified as "moderate" with a score of 53, attributed to low ownership of productive assets and highly vulnerable income levels, which limit fishers' capacity to save. It is recommended that the government address the socio-economic vulnerabilities of fishers in an integrated manner, by strengthening regulation and mediation to mitigate potential conflicts, while simultaneously initiating productive asset assistance and business diversification programs supported by financial literacy.
