Coral trout grouper seed have high economic value, but the population in nature has started to decline. The purpose of this study was to obtain a good quality of feed on the growth and stability of seeds of coral trout grouper. Research has been done with experiment container used is fiber tank with size 1m³ counted 6 tanks. The test animals used in the study were the grouper seeds from the culture. The treatments were A = protein content in 48% feed, and treatment B = feed pellet import protein content in feed 55%. Coral trout groupers are kept in fiber tanks. Density of each tank 200 etc /m³ The study used a descriptive design with 2 treatments, each treatment repeated 3 times. Data were analyzed by using ANOVA and at the end of the research was done profit ratio analysis. The results showed that both treatments were significantly different (P <0.05) on survival and daily growth (GR). The highest survival and daily growth in treatment B (SR 97.45%; GR 0,26g/ day) followed by treatment A (SR 85,50 %; GR 0,15g/day). From the economic analysis the best profit B/C ratio was 1.51 treatment B, and followed treatment A was 1.09.

The study was conducted using hafa with a volume of 1 m³ in a pond. The purpose of this study was to obtain information about the growth of second generation milkfish fry (G2), HSRT fry and wild fry that are kept controlled in hafa on ponds. The seeds used in this study were from G2, HSRT and and wild fry with a total length (TL) about 1.5-2.0 cm. Stocking density of seeds as 250 individuals/m³. The study was conducted for 3 months until the seeds reached a total length (TL) around 10.0-12.0 cm. The treatments in this research activity were (A) G2 of seeds, (B) HSRT of seeds and (C) wild of seeds. The research activities were carried out using RAL each treatment was repeated 3 times. The feed provided is in the form of commercial pellets with a protein content of around 28-30%, with a dosage of about 5-8% biomass /day and given until full/adlibitum in the morning and evening.The results showed that the fish of G2 milkfish produced better survival rate (SR) and growth (GR) in the amount of 20-25% when compared to seeds from HSRT (B) and did not different from wild seeds (C). Survival rate and growth produced were 90.20 ± 2.60%, total length of 12.80 ± 2.40 cm and weight of 35.20 ± 2.70 g.

The purpose of this study was to determine the effect of Black Soldier fly carcass flour on feed on digestibility, liver and blood features in Sangkuriang catfish (Clarias gariepinus). Sangkuriang catfish (Clarias gariepinus) used measuring 9-12 cm with a weight of ± 5.27 g. The aquariums are used as many as 5 pieces measuring 100 cm x 50 cm x 51 cm. The amountof sangkuriang catfish (Clarias gariepinus) stocked in the aquarium is 10 per aquarium and fed 6% of the total weight of all test fish. The results showed that the digestibility value of 50% black soldier fly carcass flour (CF) treatment gave the best results. In addition, the liver picture in the 50% CF treatment did not show any abnormalities in the liver of the Sangkuriang catfish (Clarias gariepinus). Amount of blood cells in 50% CF treatment is in optimal condition. Based on these results indicate that the administration of Black Soldier fly carcass flour at CF 50% treatment gives the best results on digestibility, liver picture and blood of Sangkuriang catfish (Clarias gariepinus), so that Black Soldier fly carcass flour can be used in feed formula

Salinity is one of the environmental factors that influence the body's physiological processes primarily in the osmoregulation process and impacts on growth. The purpose of this study is to see the impact of salinity on osmoregulation and growth and determine the optimum traffic for the maintenance of Panulirus longipes. This research was conducted in September 2019-January 2020, at the Balai Udang Mata Seed City, Kendari City, Southeast Sulawesi, Indonesia. The salinity tested in this study was 28, 31, and 34o/oo. The results showed that high salinity had an impact on the level of osmotic action obtained, which was higher, but a decrease in the diameter of granulocytes and hyalinocytes was getting smaller. Male lobsters have better adaptability to salinity than females, where the salinity range of 28-34o/oo can still be tolerated by not affecting growth. Conversely, females are strongly affected by salinity and the optimal support for growth is 31o/oo.

Aeromonas hydrophila is bacteria that often infect freshwater fish and causes Motile Aeromonas Septicemia (MAS) disease. One alternative antibacterial that can be used is squid ink (Loligo sp.) which contains antibacterial substances. The purpose of this study was to determine the effect of squid ink (Loligo sp.) on antibody titers and bacterial density in tilapia infected with A. hydrophila.This study used a Completely Randomized Design (CRD) with the treatment of squid ink powder in feed at a dose of 52.5 ppm (A), 62.5 ppm (B) and 72.5 ppm (C), positive control (K+) using oxytetracycline ( 20 ppm) on feed and negative control (K-) without giving treatment to feed. The main parameters observed were bacterial density in blood of tilapia (O. niloticus) and antibody titer. In addition to the main parameters, supporting parameters observed in this study included survival rate (SR), and measurements of water quality (temperature, DO and pH). The best dose in giving squid ink (Loligo sp.) powder in feed was 62.5 ppm (treatment B) because it supresing bacterial density in the blood of tilapia (O. niloticus) until 166.33 X 103 cfu/mL, decreasing antibody titer from 26.67±09.24 % to 13.00±04.62 % and highest survival rate of 90.47%.

Tilapia is a superior freshwater commodity in Indonesia. The problem with tilapia farmers is the high price of commercial feed because raw materials are still imported. Alternative materials are needed to reduce the cost of feed. One of the treatments is by substituting local raw materials that can stimulate the growth of tilapia, namely by substituting a combination of earrings spinach flour and bean sprouts in the artificial feed that is useful to spur the growth of cultivated tilapia. This study aims to determine the best dose substitution and effect of earrings spinach flour and waste sprouts flour on artificial feed to the efficiency of feed utilization and growth of tilapia fish (Oreochromis niloticus). The method used is an experimental method with a Completely Randomized Design (CRD) with 4 treatments and 3 repetitions. Test fish used was tilapia with an average weight of 3.37 ± 0.16 grams which were kept in a bucket of 15 L. water. The combination of earrings amaranth flour and bean sprouts flour used was in the ratio of 0%: 0% (A), 100 %: 0% (B), 50%: 50% (C) and 0%: 100% (D). Observation variables included the efficiency of feed utilization, growth, life pass, and water quality. The best results of this study were 50%: 50% (C) with, RGR, EPP, FCR, PER, TKP and Survival, respectively, 76.60 ± 3.07% / day, 76.60 ± 3 , 07%, 1.31 ± 0.05, 2.25 ± 0.04% 91.37 ± 1.45 grams and 86.67 ± 6.67a%. Water quality results in maintenance in the optimal range.
