Abstract

Catfish is one of the freshwater commodities whose demand continues to increase in Indonesia. Intensive cultivation is done to meet market demand. Intensive cultivation is done by optimizing stocking density. The aim of this research was to know the effect of different density on feed productivity, growth, feed conversion ratio (FCR) and survival of catfish dumbo fry (Clarias gariepinus, Burch) in biofloc and nitrobacter media. This study used a completely randomized design (RAL) with 6 treatments and 3 replications. The test animalsused catfish dumbo (Clarias gariepinus, Burch) with an average weight of 0,6 ± 0,1g and an average length of 4 cm. Catfish dombo seeds are kept in tarpaulin ponds 2 m in diameter with water volume ± 1 m3 for 45 days and feeding 3% of biomass weight. The results showed that the different density of stockingin biofloc and nitrobacter media had increase on productivity, specific growth rate, feed efficiency and no significant effect on the survival of catfish dumbo fry.

Abstract

The local government law regulated the management of 0 – 12 miles waters carried out by the province so that fishermen can operate their fishing gear without differentiating districts. Catch fishing was not limited to one kind of fishing gear and it caused the increasing of fishing capacity. The limited area of fishing with the distance of 2 miles from coast can caused fisheries utilization resources was not balanced. Therefore this study needed to be conducted to assess the status of development of gillnet fishing activities in Dumai waters. Data was collected by conducting interviews in the form of: fishing units, selectivity, sustainability of function and size of fishing vessel with legal documents, and modification of fishing gear. The data results based on 5 fishing technical aspects explained that the fishing utilization of gillnet still could be developed. However, the data of fishing vessel documents have to be well recorded according to the reality so that government could develop the responsible fishing activities.

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

The escalating need for animal protein has stimulated the growth of the capture fisheries industry. However, undue carelessness concerning the maintenance and operation of fishing vessels often results in scenarios that pose serious risks, even leading to fatal accidents. In Karawang District, the high spirit of fishermen in setting sail plays a major role in boosting the productivity in the capture fisheries sector. Yet, the awareness of the importance of using personal safety equipment while at sea remains disappointingly low. The Fish Capture Study Program of the Politeknik Kelautan dan Perikanan Karawang set out to organize a training sessions aimed for enhancing the fishermen’s awareness of safety during their voyages. These sessions are a manifestation of the social responsibility in empowering the community and promoting sustainable development. Through presentations, and direct demonstrations, fishermen are instructed on various aspects of safety during their voyage. The training includes techniques for self-preservation at sea, use of the red hand flare, activation of parachute signals, and smoke signals during emergencies, as well as the use of life buoys and life jackets to enhance safety at sea. This community service activity was attended by 20 fishermen residing on the coast of Karawang District. The initiative attempts to strike a balance between the urgency to meet the growing demands for animal protein, and the obligation to promote safe and sustainable practices in the capture fisheries sector.

Abstract

Pekalongan National Fishing Port (PPN Pekalongan), a type B fishing port, is recognized for its well-managed facilities and serves as an operational base for purse seine vessels. Purse seines are widely employed to harvest schooling pelagic fish, most of which are species of high economic value, thus requiring appropriate handling to maintain quality. This study aims to examine the handling practices of purse seine catches on board KM. Bintang Mas Maritim, focusing on storage temperature, handling equipment, and storage duration under freezer-based systems. Data collected included fish temperature at hauling, during freezing, and after storage, as well as the handling methods and equipment used by fishermen. The initial body temperature of the fish was 29.3°C at hauling. Fish were sorted by species, size, and quality, then washed and frozen at -18°C for 24 hours. Once frozen, they were packaged and transferred to the fish hold at -13.7°C for storage. The findings highlight the importance of systematic handling, washing, rapid freezing, and controlled storage—to maintain fish quality and extend shelf life.
