Food waste in urban areas is an endless problem, considering that waste will continue to exist. The technique of managing waste to become an alternative feed for catfish is one of the steps to overcome the problem of waste and at the same time becomes an alternative fish feed solution for fish cultivators. The purpose of this research is to process food waste into fish feed. The method used in writing this article is literature review. Based on the results of the literature review and the author's analysis, it can be concluded that food ingredients that can be processed into catfish feed are food waste by utilizing fermentation or by mixing or formulated with other raw materials such as (fish meal, magot, tofu dregs, and fine bran). The fermentation process can use fishery products sold in the market, including (EM4, Boster, etc) which are mixed with molasses.

The waters of Taman Nasional Bali Barat are one of the waters that have abundant diversity of marine ecosystems. Seagrass is an ecosystem that has many benefits for organisms that live in it, one of which is bivalves. Bivalves can be used as jewelry, food sources, and are often used as bioindicators of pollution. Seagrass and bivalves have the same characteristics related to the type of substrate that serve as habitat and need each other in both growth and reproduction processes. This study aims to determine the condition of seagrass cover, the abundance and diversity of bivalves, and the relationship between seagrass cover and bivalves density. This research was conducted at 3 stations, namely Karang Sewu, Terima Bay, and Labuhan Lalang in August 2020. This research was conducted using survey method and sampling technique using a purposive sampling method. To determine the relationship between seagrass cover and bivalves density using a linear regression test. The results showed that the seagrass cover at the three stations was 31.04%, 50.46%, and 50.68%. Bivalves density in Karang Sewu Bay was 29.8% Aomalodiscus squamosus, Terima Bay with 50% Pinna bicolor, and Labuhan Lalang with 30.4% Trachycardium flavum and Pinna bicolor. Based on the linear regression test, it showed a significant value 0.5 which means that there is the relationship between seagrass cover and the density of bivalves found in the waters of Taman Nasional Bali Barat.Keywords:seagrassbivalvesdensityecosystemcommunity structure

Bali Strait water has contributed to the production of pelagic capture fisheries in FMA-573. The potential for fisheries in the Bali Strait is very diverse, especially small pelagic fish such as frigate tuna, bullet tuna, bali sardinella, scad fish and mackerel. Frigate tuna (Auxis thazard) is a pelagic fish from the Scombridae family. This fish can be found in tropical and subtropical waters. Information regarding frigate tuna on the southern coast of the Bali Strait has yet to be found to date. This research aims to reveal morphoregression, which includes the length-length relationship and growth patterns, as well as the condition of frigate tuna in the southern coastal waters of the Bali Strait for ecosystem-based fisheries management. Sampling of frigate tuna was carried out from February to July 2024. Fish samples were taken from traditional fishermen who used gill nets as fishing gear in the southern coastal waters of the Bali Strait. Each fish sample was measured for total length, fork length, and standard length and weighed to analyze the length-length relationship, growth patterns, and condition factors. The number of frigate tuna caught during the research was 356. The total length of the samples caught ranged from 274 – 416 mm, weighing 270.3 – 972.4 grams. Each character of the length of the frigate tuna has a close relationship. The fork length character is the most precise in estimating fish weight, so the fork length character is used to analyze the length-weight relationship. The growth pattern of frigate tuna is positive allometric with good conditions. The results of this research can be used as a basis for ecosystem-based management of tuna fisheries.

Rasbora fish is a local Indonesian fish whose population has decreased. In the Province of Bali this fish is called the Nyalian fish and no one has cultivated this fish. Nyalian fish in Bali Province are used as consumption fish and have potential as freshwater ornamental fish. Catching Nyalian fish continuously can cause this fish decrease in population and can cause extinction. Nyalian fish conservation can be done by domestication and adapting fish caught from their natural habitat to aquaculture aquarium, then used in aquaculture activities and ensuring continuity of numbers and avoiding extinction. During the domestication process, the Nyalian fish will experience stress due to changes in their habitat. Stress in fish can be shown by a drastically darker body condition. Parts of the body that blacken or show a darker color are due to the activity of melanin as an active role in it. The Tyrosinase gene is one of the genes responsible for coding pigment patterns. The TYR gene has an important role in instructing the formation of the enzyme Tyrosinase.

The aim of this community service is to improve the knowledge, skills and attitudes of cultivators, especially lobster cultivators. Training and counseling is carried out directly in the field, with material first provided, practice carried out, and the discussion concluded. The venue for the event was Ekas Buana Village in Jerowaru District, East Lombok Regency, West Nusa Tenggara Province. The first step in making fermented feed is to determine the feed formulation, weigh the feed, and then mix the starting feed with the smallest amount of feed ingredients. Followed by fermentation and steaming of the feed. The feed produced from this fermentation can be used to feed lobsters, especially in musism where trash feed and squid or natural feed are difficult to find

Use of Fermented Japanese Papaya (Cindoscolus Aconitifolius) Leaf Flour as an Alternative Feed to Increase the Production and Quality of Tilapia (Oreochromis Niloticus) Rejeki, I Gusti Ayu Dewi Seri; Arya, I Wayan; Suryani, Sang Ayu Made Putri

Tilapia (Oreochromis niloticus) is a type of aquaculture commodity that has high economic value as a freshwater consumption fish in the world. Efforts to increase the quantity and quality of commercial feed have an impact on the operational costs of intensive fish farming, namely more than (60-70%) of the total production costs. One effort to overcome dependence on imported feed raw materials is the use of local raw materials. The local raw materials used must have high nutritional value, be non-toxic, relatively cheap, very abundant and not compete with human needs, including Japanese papaya leaves. The use of Japanese papaya leaf flour as a source of carbohydrates and protein in fish feed cannot be done optimally because it contains high levels of fiber and tannin which can bind the minerals needed by fish.

Mangrove forest ecosystems are vegetative communities found in tropical and subtropical estuaries and shallow coastal lagoons. They are mostly composed of several types of mangrove trees that can thrive in muddy beach tidal zones. The science and art of remote sensing involves analyzing data collected using instruments without coming into direct touch with the thing, location, or phenomena being researched in order to learn more about it. Sentinel-2A is a medium spatial resolution satellite image with a wide swath that can be used for studies on land cover monitoring, including vegetation, soil, and water, as well as water networks and coastal areas. It revisits the same location every 5 days, as opposed to Landsat's 16-day interval. The research findings indicate that there was an increase in the development of mangrove density between 2019 and 2023. Specifically, the total area of mangrove forests rose from 118.59 Ha in 2019 to 145.44 Ha in 2023. These developments are displayed in the table below
