Abstract

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.

Abstract

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

Abstract

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.

Abstract

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

Abstract

Rumput laut sebagai salah satu komoditas ekonomis penting dan merupakan salah satu sumber pangan dunia merupakan salah satu produk primadona di sector budidaya perikanan. Budidaya rumput laut relative mudah dibudidayakan, tidak memerlukan modal yang besar, tidak ada petisida, tidak ada residu dan tanpa pemberian pakan. Berdasarkan segi kualitas air yang berada di wilayah Bali yang mendukung pertumbuhan rumput laut dan juga sinar cahaya matahari yang cukup sehingga potensi dalam budidaya rumput laut sangat besar dan juga menguntungkan. Penelitian ini bertujuan untuk mengetahui seberapa besar potensi luasan wilayah yang dapat digunakan untuk budidaya rumput laut. Metode dalam penelitian ini yang digunakan ialah literatur review. Hasil analisis kesesuaian lahan di bali mendapatkan lahan potensial untuk budidaya rumput laut adalah perairan Pulau Nusa Lembongan sebesar 3.375,65 Ha. Luas lahan efektif sebesar 2.025,39 Ha yaitu 60% dari luas, serta total produksi pada satu musim panen sebesar 89.117,16 ton/siklus panen. Hasil pengukuran kualitas perairan menunjukkan parameter optimal yang meliputi suhu perairan 26 s.d 31 oC, salinitas 28 s.d 35 ppt, dan kedalaman 30 cm s.d 1 meter.

Abstract

The Mina Ayu group in Desa Baru, Tabanan, Bali, has significant potential in agriculture, fisheries, and tourism, particularly tilapia (Oreochromis niloticus) aquaculture supported by abundant freshwater resources. Since 2018, the community has developed tilapia hatchery production that reached wider markets; however, management remains suboptimal due to fish disease outbreaks and limited use of natural remedies. Neem (Azadirachta indica) leaves contain bioactive compounds with antibacterial, antioxidant, and immunostimulant properties, making them a promising alternative for sustainable aquaculture disease control. This program aimed to improve tilapia production and quality through neem leaf extract application, strengthen financial management, and enhance the economic independence of the Mina Ayu group. The community engagement program was conducted from August to October 2025 with 12 members of the Mina Ayu group. Methods included interviews, group discussions, lectures, training on neem extract preparation and application, field practice, and mentoring on financial management and marketing strategies. The program resulted in a significant improvement in farmers’ understanding of fish disease control and water quality management. The application of neem leaf extract in tilapia feed increased the survival rate from 60% to 100% and enhanced fish growth performance and resistance. Group members successfully produced both liquid and powdered neem extract and adopted simple financial recording tools such as daily cash books and profit–loss statements. Training also improved financial literacy, social media–based marketing, and overall business efficiency. The utilization of neem leaf extract effectively improved tilapia aquaculture performance while strengthening financial literacy, thereby supporting business sustainability and the community’s economic independence.
