Oryzias celebensis is a species of medaka fish in South Sulawesi. During incubation, the growth and development of these fish embryos depend on the nutrients stored in the eggs. Therefore, this study aimed to determine the volume size of egg yolks and oil droplets and the absorption rate of egg yolks of O. celebensis embryos that reared in different incubation media. The study was conducted using a completely randomized design (CRD) with four rearing media treatments, namely A (Early Rearing Media), B (bottled water), C (Pattunuang river water) and D (well water) with five replications . The results showed that the volume of egg yolk and O. celebensis embryo oil in each medium showed a decrease in volume size along with the embryonic development stage. The absorption rate of yolk in O. celebensis embryos in media A had the biggest yolk absorption with an average 0.015±0.038 mm3 while media D had the smallest yolk absorption with an average 0.011±0.022 mm3.

One of the common diseases found in tilapia is a streptococcal disease caused by the Streptococcus agalactiae bacteria. Treatment of this disease is generally done by using antibiotics. The use of antibiotics in controlling disease in fish can create resistant bacterial strains with certain doses. The use of vaccines is one of the alternative control methods in fish defence against infections. The purpose of this study was to analyze the efficacy of vaccination on seeds through immersion using attenuated active bacteria to increase immunity at the beginning of the spread of streptococcosis disease. The vaccine used was obtained from attenuated Streptococcus agalactiae bacteria through repeated passage ten times. Vaccination was carried out through oral vaccine. Challenge tests were carried out on days 7, 14, and 21 days after vaccination on tilapia larvae by immersion. The result indicated that vaccination using attenuated bacteria could increase lysozyme activity at each observation time compared to control. The mortality of post-challenged larvae on days 7, 14 and 21 post-vaccination was lower than that of unvaccinated seed. The percentage of RPS values up to the 14th day of observation has increased and tends to decrease on the 21st day.

Fish is a source of high-quality protein. Protein in fish has a complete composition and amount of essential amino acids. However, fish is a type of food that is susceptible to biological damage and is susceptible to microbial contamination so that it quickly decays. One of the most important microorganisms in spoilage of fish meat is Escherichia coli bacteria. This study aims to determine the presence of Escherichia coli bacteria in scad, tuna and skipjack tuna. The research was carried out from July to September 2021. The research method used was a sample survey method, sampling was carried out at 3 market locations, namely the TPI market and the tasiu market. Furthermore, the samples were analyzed at the Laboratory of Fish Quarantine and Quality Control Center (BKIPM) Mamuju, West Sulawesi. The results showed that the largest E.coli content was found in tuna 1 in the TPI market, which was 20 MPN/g, and the smallest E.coli content was < 3 MPN/g, namely scad fish 1 in the tasiu and TPI markets, tuna 1 and 2 in the TPI market, tuna 2 in TPI market.

Efforts to reduce protein in fish feed by maximizing the use of carbohydrates as an energy source must be supported by exogenous enzymes. One source of exogenous enzymes that can be used as a polysaccharide degrading agent easily obtained and wasted is rumen liquid in slaughterhouses (RPH). This study aims to determine the most effective carbohydrate level after being given rumen liquid as a source of exogenous enzymes in maximizing nutrient digestibility and feed efficiency in milkfish (Chanos chanos Forsskal). This study was designed using a Completely Randomized Design (CRD) which consisted of 4 treatments and three replications. Thus there were 12 experimental units. The treatments tested were feeds with various levels of carbohydrates (27.81%; 39.50%; 46.97%; and 56.75%) then given cow rumen liquid as a source of the enzyme at a dose of 80 mL/100 g of feed. Nutrient digestibility and feed efficiency data obtained were analyzed by analysis of variance (ANOVA) and continued with the W-Tuckey test. The results showed that feeding with various levels of carbohydrates in the feed that was first given cow rumen liquid waste had a significant effect (P<0.05) on fibre digestibility, carbohydrate digestibility, and feed efficiency of milkfish, but had no significant impact (P>0.05) on total digestibility, protein digestibility, and fat digestibility of milkfish. The most effective carbohydrate level in feed after being given cow rumen liquid which can optimize nutrient digestibility and feed efficiency of milkfish, is 46.97%.

Betta fish (Betta sp) is a freshwater ornamental fish during the pandemic that is very popular with the public. However, people tend to prefer male betta fish than female fish. To deal with the large number of requests, a sex reversal technique is carried out which applies hormonal engineering to change female to male sexual characters (masculinization) using natural ingredients, namely cow testicle flour. The purpose of this study was to analyze the dose of bovine testicular flour hormone on the process of oral male betta fish larvae. This research was conducted in Moncongloe Village, Maros Regency, from July to September 2021. The production of beef testicle flour was carried out in the Chemical Engineering laboratory, Ujung Pandang State Polytechnic. Betta fish seeds were kept each in an aquarium measuring 20 cm x 14 cm x 20 cm as many as 12 pieces. Soaking artemia with beef testicle flour with a predetermined dose of 60 mg L-1, 80 mg L-1 and 100 mg L-1, the duration of immersion is 24 hours. This study used a one-factor completely randomized design (CRD). The results obtained were the highest percentage of male genitalia at a dose of 100 mg L-1 with a percentage of 66.7%. The survival rate of betta fish during the maintenance period with different doses of cow testicles obtained data ranging from 80-100%.

This study examines the concept of Hybrid Event as a new strategy that is considered reliable enough for fishing communities in Makassar to face new normal conditions. New economic spaces have been created for fishermen and UMKM fishermen who have been affected by Covid-19. The old economic spaces are no longer reliable because they are constrained by laws and regulations from the government that require restrictions on social distancing and physical distancing. The purpose of this study was to analyze the readiness of the fishing community and fishermen UMKM actors in Beba, Tamasaju Village, North Galesong District, Takalar Regency to enter business era 4.0 in the midst of the Covid-19 pandemic and assist the realization of government policies in providing socio-economic protection to fishing communities and as well as UMKM fishermen in Makassar. The resulting output is in the form of four (4) main strategies: first, combining physical and virtual meetings, so that fishermen's businesses and businesses and fishermen's UMKM continue to run in various different atmospheres. Second, health protocols such as maintaining physical distance and social distance are not violated and at the same time the pace of economic activity of fishing communities and fishing UMKM can still run normally. Third, empowering fishing communities and fishing UMKM in using appropriate information technology. And fourth, the government's budget policy for fishing communities and fishing UMKM that are oriented to the provision of appropriate information technology

Research has been done on the model of nutrient distribution and current pattern in coastal water of Tanjungpinang City. The research objective was to develop a model of nutrient distribution and current patterns in coastal waters and small islands as an effort to manage the eutofication of coastal waters and small islands in the archipelago. Determining the location of the observations was done by purposive sampling at high tide and low tide at several predetermined research stations. The results showed the nutrient distribution model in the waters of Tanjungpinang Bay, a different distribution pattern compared to the waters of the Dompak Strait, with the distribution of nutrients from the yield model at low tide and at high tide shows the same pattern, which tends to decrease offshore and high in some coastal locations. around the waters of the Sei. Carang estuary which is connected to the waters of Tanjungpinang Bay. The pattern of currents during the highest tide is bandage and full moon in coastal waters and small islands in the area of Tanjungpinang City, which shows that the inlet flows from the west of the waters, then exits towards the north into open water. However, part of the water mass in the presence of small islands around it becomes fragmented causing a turn to the south of the coastal waters of the city of Tanjungpinang, with a maximum current speed of 1.1 m/s.

The research objective was to develop a model of nutrient distribution and current patterns in coastal waters and small islands as an effort to manage the eutofication of coastal waters and small islands in the archipelago. Determining the location of the observations was done by purposive sampling at high tide and low tide at several predetermined research stations.
