Vannamei shrimp cultivation in Indonesia has begun in East Java. Farmers in East Java cultivate vannamei shrimp, in fact 90% of farmers have replaced the tiger prawns they cultivate with vannamei shrimp. With the increase in vannamei shrimp cultivation, it is necessary to provide continuous and quality fry, so it is hoped that it will be able to increase the productivity of vannamei shrimp. The purpose of this writing is to determine techniques for rearing vannamei shrimp larvae (Litopenaeus Vannamei) at PT. Delta Windu Purnama Situbondo, East Java. The methods used in rearing vannamei shrimp larvae start from preparing rearing tanks, preparing equipment, installing aeration, fumigation of rearing rooms, preparing rearing water, stocking naupli, managing feed, managing water quality and harvesting and packaging the fry. The results obtained were that the number of larval populations produced at the end of the rearing period in tank B1 was 2,000,000 with a survival rate of 80% and in tank B5 was 2,370,000 with a survival rate of 94.8%. The population number and survival rate of vannamei shrimp larvae will decrease along with the change of larval stage which is influenced by environmental conditions and food availability. The water quality parameters for rearing vannamei shrimp larvae that were measured were temperature 28-31.5°C, salinity 30-31 ppt, pH 7.7-8.1 and dissolved oxygen 5-5.7 mg/l.

In addition to having high economic value, catfish (Clarias sp.) can also be cultivated quickly and they can adapt well. The demand of catfish is in line with the increase in production which is expected to remain efficient and environmentally sound. Biofloc technology has also been implemented in catfish for increasing productivity. Biofloc utilizes the activity of heterotrophic microorganisms and autotrophs for the conversion of organic waste into floc and is used as fish feed. This study aims to examine the effect of the use of molasses with different doses (C/N ratio) on the growth and survival rate of catfish. This study was conducted with as many as 3 treatments with 3 repetitions each except for the control. The treatment with the ratio of molasses in each of them: A: C/N of 10:1; B: C/N of 15:1; C: C/N of 20:1, and D without molasses given as control. The study using 240 catfish measuring 10-12 cm was carried out for 30 days with sampling every 10 days. It aims to determine the average growth, daily growth, and survival rate of test biota during the study. Based on the results of this study, it can be concluded that the use of different doses of molasses in catfish farming, and biofloc technology will affect the growth and survival rate of farmed catfish. Catfish farmed with biofloc technology at a C/N ratio of 15:1 show the best results on their growth and survival rate. In addition, catfish farming with a biofloc C/N ratio of 15:1 has a better economic analysis when compared to conventional catfish farming. In summary, the use of biofloc based on research results can be a recommendation to be applied in the community, especially among catfish farmers.

ABSTRACTSiamese catfish (Pangasianodon hypopthalamus) is a type of fish that is included in the catfish group, this fish has a fairly large market so the demand for catfish is increasing from year to year. The main obstacle to the production of catfish seeds is the spawning cycle of Siamese catfish which still depends on the season, so optimization is needed in the supply of seeds through artificial spawning with the help of hormonal stimulation. This study aims to examine techniques for artificially hatching Siamese catfish using the hormone ovaprime and evaluate the performance of Siamese catfish hatcheries. The time for carrying out this research was 3 months using the observation method, participating directly in Siamese catfish hatchery techniques and through interviewing sources in the field of catfish hatchery. Siamese catfish hatchery techniques start from preparing the container, rearing the brood stock, selecting the brood stock, spawning, injecting, stripping, fertilizing, hatching, and raising the larvae until they become seeds and are ready for distribution. Based on the results of research on artificial seeding techniques for Siamese Catfish (Pangasianodon hypopthalamus) at the Gelam Jambi River Freshwater Aquaculture Fisheries Center (BPBAT), it produces an average fecundity of 170,394.75 eggs/kg. Meanwhile, the fertilization rate for four cycles averaged 69.54%, and the hatching rate was 68.95%. The problem with hatching Siamese catfish at BPBAT Sungai Gelam is that the availability of natural food is not sufficient for the needs and quantity required for larvae at the start of rearing, causing a decrease in larval survival rates.Keywords: Hatchery techniques, Siamese catfish, Pangasius hypophthalmus, artificially, seeds

The vannamei shrimp (Litopenaeus vannamei) is one of the most popular shrimp species, widely cultivated throughout Indonesia. This species has several advantages, including rapid growth, the ability to be cultivated at high densities in intensive systems, and resilience to environmental changes. The presence of plankton and the quality of water in the cultivation medium significantly affect the growth and survival of vannamei shrimp. This study aims to evaluate plankton abundance and the dynamics of water quality in intensive vannamei shrimp farming. The research was conducted at two intensive vannamei shrimp farms in East Java with shrimp aged between 1 and 60 days. Water quality measurements were taken directly from the cultivation ponds (salinity, pH, and dissolved oxygen) and in the laboratory (ammonia, nitrite, phosphate, alkalinity, and total organic content). The average abundance of plankton in the intensive vannamei shrimp farming medium ranged from 190 x 10³ to 960 x 10³ individuals/mL, consisting of four groups: green algae, diatoms, dinoflagellates, and blue-green algae. Green algae were the most abundant group, making up 69.9% to 71.9%, while diatoms were the least abundant at 1.9% to 3.0%. In intensive vannamei shrimp farming, the salinity of the cultivation medium ranged from 16 to 35 ppt, pH from 7.5 to 9.0, dissolved oxygen from 3.2 to 5.7 mg/L, and temperature from 28.0 to 31.3°C. The water chemistry parameters measured were ammonia, nitrite, phosphate, alkalinity, and total organic content, with respective ranges of 0.001–0.030 mg/L, 0.05–1.00 mg/L, 0.25–3.00 mg/L, 104–232 mg/L, and 27–131 mg/L. The dynamics of water quality remained within the optimal range for vannamei shrimp farming, as outlined in Regulation KP Number 75 of 2016 regarding general guidelines for the rearing of tiger shrimp and vannamei shrimp.

Vannamei shrimp (Litopenaeus vannamei) is a high-value aquaculture commodity. However, during the post-larval rearing phase, fluctuations in water quality and high abundance of Vibrio can cause stress and larval mortality. Therefore, evaluation of rearing practices and water quality is important to support successful juvenile shrimp production. This study aims to evaluate water quality, health, and growth of vannamei shrimp juveniles during the post-larval rearing period. Rearing was conducted from PL4–5 to PL10–11 using three tanks measuring 6 x 4 x 2 meters (water volume 40 tons), each labeled A6, B4, and B11. The fry quality results showed that all tanks achieved grade A, with optimal stadia development and gut muscle ratio. Observations on juvenile shrimp health revealed no necrosis, low Vibrio infection, and high stress resistance. Observations on post-larval growth showed an average length of 7.76–9.27 mm and an average survival rate of 88%, exceeding the minimum standard of SNI 7311:2009. Therefore, effective water quality management and control of Vibrio abundance during the rearing period of shrimp post-larvae can significantly improve the survival rate and quality of vannamei shrimp post-larvae.
