One of the solutions to maximize diet usage when the feeding is not in line with the growth of Catfish (Pangasius hypothalamus) is by introduction of fish new culture system. The new culture system is by incorporating Saccharomyces cerevisiae into the feed. It aims to increase feed efficiency; in turn it increases the growth. The objective of the research is to study the effects of S.cereviceae incorporated diet on growth performance, apparent digestibility coefficient of protein and survival rate of catfish (P. hypothalamus). The fish used in the study were 4.02±0.22 g per fish. The study used experimental method with completely random Design. The experiments were in 4 (four) treatments. Each treatment had 4 (four) repetitions. The treatments were by feeding fish with 4 (four) different dosages of S. cerevisiae addition in the diet. The dosages were 0 g per kg feed (A), 0.5 g per kg feed (B), 1 g per kg feed (C) and 2 g per kg feed (D). The results show that the incorporated S. cerevisiae feed was significant (P<0.05) on the specific growth rate (SGR), apparent digestibility coefficient of protein (ADCP) and survival rate (SR) of the catfish (P. hypothalamus) fingerlings. The best dosage was 1.0 g of S. cerevisiae per kg feed and the optimum dosage ranged from 1 to 1.12 g/kg feed for SGR, ADCP and SR of the Catfish (P. hypothalamus) fingerlings.

Vitamin C and E have important roles in the process of reproduction, immune system, and anti-oxidants to protect cell membrane lipid, and the circulation of essential fatty acid in the body of the aquatic organism including shrimp. The aims of this study was to analyze the effect of vitamin C and E supplementation in modified-commercial diet on the fatty acids profile of hepatopancreas and oocyte of tiger shrimp, Penaeus monodon. The experimental treatments were: modified-commercial diet by supplementing with vitamin C (500 mg/kg) and E (300 mg/kg) (PS), and modified-commercial diet without vitamins supplementation (PK). Cultured tiger shrimp were used as the animal with initial weight of 43.1 ± 5.1 g (mean±STD) for females and 41.9 ± 4.4 g for males. The shrimps were cultured in two of 1000 m2 concrete ponds with a density of 100 shrimp / pond. During three months culture in the pond, they were fed the test at rate of 3% biomass/day. When the tiger shrimp reached the weight over 90 g for females and > 70 g for males, then the shrimp were transferred to concrete tanks for oocyte maturation evaluation. In maturation tank, the shrimp fed test diets (pellet) combined with fresh food (squid) as much as 3% (dry basis) at combination ratio of 50% : 50%. Shrimp reaching oocyte development stage III were dissected and sampled for hepatopancreas and oocytes for analysis of fatty acid profile. The results showed that the hepatopancrea and oocyte fatty acids contents were higher in the tiger shrimp fed PS compared to the tiger shrimp fed PK. The poly unsaturated fatty acid (PUFA) especially for arachidonic, docosahexaenoic, and eicosapentaenoic acid were higher in shrimp fed with PS than the shrimp fed PK. Despite higher total fatty acid contents in hepatopancreas than in oocyte for the both treatments, the esensial fatty acid arachidonic, docosahexaenoic, and eicosapentaenoic acid were higher in oocyte than in hepatopancreas of the shrimp. This suggested that these three types of PUFA played important role for oocyte development for female reproduction. Supplementation of vitamin C and E in the test diet had an effect on increasing PUFA content in hepatopancreas and oocytes of tiger shrimp.

Total landings of capture and culture fisheries in Korea increased from 1,073,000 metric tons (MT) in 1971 to 3,743,000 MT in 2017 mainly due to the development in marine aquaculture practices. During last four decades, marine aquaculture production in Korea showed around 5-fold increase from 491,000 MT in 1977 to 2,310,000 MT in 2017 recording the value of 2.9 billion USD. Last year, the main production was derived from seaweed (1,755,630 MT), while the aquatic animal production was made from shellfish (428,160 MT), fish (86,400 MT), crustacean (mainly shrimp of 5,100 MT) and others (34,530 MT). Inland aquaculture is based on fish farming with the production of around 25,000 MT. Either trash fish or moist pellet based on the raw fish is still being fed to marine culture fish, which is the main obstacle for developing the farming. In 2017, around 450,000 MT of trash fish with 87,980 MT of extruded pellets were employed to produce 86,399 MT of marine fish.

A part of S. tranquebarica crablet offspring produced from larvae rearing often grows faster than the others. The research aimed to monitor larvae development and compared the growth between fast and slow growth crablet offspring. Hatched larvae reared until crablet stage with production 4848 individual. 600 individual were weighted and measured carapace width. The data figured as a normal distribution curve. 700 ind. of fast growth crablet with carapace width 15.2+1.29 mm and body weight 0.55+0.15 g/ind. were selected. The others 700 individual slow growth crablet, carapace width 8.88+3.11 mm and body weight 0.14+0.08 g/individual were selected also. These crablet stocked in four pond compartments each size of 500 m2 (350 ind./500 m2). Crablet growth was monitored monthly. After five months cultured, the fast growth crablet attained 185.7+38.7 g/ind. and significantly different (P<0.05) with the slow growth crablet 156.94+15.30 g/ind. The first female mature gonadal stage with weight 205.2+0.3g and carapace width 116.7+0.7mm was obtained from the fast growth crablet group after fourth months cultured. That female mature gonadal was spawned after 27 days incubated in the hatchery. Fast growth crablet is concluded more effective for the broodstock candidate in mud crab hatchery.

Abalone (Haliotis squamata) is one of the fisheries commodities that have high economic value. This study was conducted to investigate contamination of Escherichia coli and coliform in Abalone cultivation ponds in the Musi Village area, Buleleng Regency, Bali. An experiment was carried out by taking water samples in the abalone pond every week for one month. The results showed that there was no difference between the total number of Escherichia coli and coliform. Water samples that were positive for coliform in the determination test had no differences in each sample with total coliform values (Colonies / 100mL) of 4, 3, 7 and 9 (MPN / 100mL) respectively. While the total number of Escherichia coli is shown after being grown in EMBA selective media which are 4, 3, 7, 4 (MPN / 100mL) respectively. Meanwhile, when compared with the number referenced from the Decree of the State Minister of Environment Number 51 of 2004 concerning Sea Water Quality Standards, the quality of seawater for aquatic cultivation in this study is still classified as Safe (<1000 MPN / 100mL).

This study was conducted to evaluate the immunomodulatory activity and diseases resistance of concoction Boesenbergia pandurata/BP, Solanum ferox/SF, and Zingiber zerumbet/ZZ extract (SF, BP, and ZZ) in tilapia with the concentrations 600 mg/L BP, 900 mg/L SF and 200 mg/L ZZ against Aeromonas hydrophila and Pseudomonas fluorescens. Immunomodulatory activity was measured by testing the concoction of three plants extract to preventive and treatment pathogen infection (A. hydrophila and P. fluorescens 105colony-forming units per milliliter each bacteria). In this research, using feed administration method, the concoction of extract BP:SF:ZZ ratio was 1:1:1 and extract is given for 14 days as much as three times a day (3-5% of fish body weight). The immunomodulatory parameters (white blood cell/WBC, red blood cell/RBC, phagocytic index/IP) and relative presentation survival/RPS was observed at week 4th after challenges with bacteria through intramuscularly injection (0.1 mL/fish). The number of white blood cell (WBC) was increased significantly (P <0.05) compared to controls without extract and it also happens with red blood cell (RBC), phagocytic index also experienced a significant increasing in fish fed with combined extracts compared to controls. The results of this study indicate that giving concoction of three extracts provides the best protection (RPS) against infection of A. hydrophila and P. fluorescent. The conclusion this research is concoction of SF:BP:ZZ in the ratio of 1:1:1 have a immunomodulatory effect in tilapia and increasing protection against bacterial infections

The aim of the study was to investigate the effect of different types of carbohydrates on growth, survival, feed efficiency and fish production (Pangasius pangasius), in the biofloc system with zero-water exchange. Added carbohydrates were tapioca, molasses, bran and cornstarch which were set at level of 25% of the theoretical adding quantity. A total of 6000 fish larvae used in this experiments. Complete Randomized Designed was used with four treatments and three replications. Twelve tanks used in which each tank was a cylinder tank (1814.92 L) and each tank contained 500 fish. The results showed that the concentrations of ammonia and nitrite differ significantly in the experimental tank added maize when compared to other carbohydrate sources. The nitrate levels showed that highly concentration was observed in the maize treatments compare to tapioca and molasses treatments, however it was not significantly different than that of rice bran treatments. The floc volume stabilized after about 3 weeks in the BFT tanks. Different carbon sources had resulted in different proximate composition tendencies. The highest yield obtained in molasses treatments which were highest compare to all carbohydrate treatments, whilst tapioca, rice bran, and maize treatments were not significantly different
