MAS disease (Motile Aeromonas Septicemia) is a disease caused by A. hydrophila bacteria that attack tilapia and other freshwater fish species. The use of antibotics and chemicals in the continuous prevention and treatment of this disease can damage the aquatic environment and can cause bacterial resistance to antibotics, so antibotic use becomes ineffective. The study used a Complete RandomIzed Design (RAL) with an experimental method consisting of 5 treatments and 3 repeats. Treatment in this study is (P1) without soaking garlic extract and without infected bacteria Aeromonas hydrophila, (P2) without soaking garlic extract and infected bacteria Aeromonas hydrophila, (P3) soaking garlic extract with a concentration of 1% and disinfection of bacteria Aeromonas hydrophila, (P4) immersion of garlic extract with a concentration of 1.5% and infected bacteria Aeromonas hydrophila, (P5) soaked garlic extract with a concentration of 2% and infected with Aeromonas hydrophila bacteria. The results showed that the SR value of tilapia fish in each treatment had values ranging from 0.0% to 66.7%. Relative percent survival (RPS) tilapia seeds in each treatment have values ranging from 0.0% to 66.7%. The conclusion of this study is that giving garlic extract with different concentrations has a real different influence on survival rates and relative percent survival (RPS).

The problem with gouramy cultivation was slow growth due to the short intestines of gouramy so that the absorption of feed takes longer and less. Several previous studies used temulawak in the form of flour, extract, oil which was applied to carp, tilapia, milkfish, catfish. The addition of extract, temulawak flour to the feed gave an increase in growth both in length and weight in the test fish. The purpose of this study was to determine whether or not the effect of temulawak extract on the growth of gouramy fish. This research was conducted for 45 days. This research was conducted by experimental method using a completely randomized design (CRD) with 5 treatments (P) 3 times replication (U), in order to obtain 15 experimental units. Treatment 0 Control (without temulawak extract), Treatment 1 Provision of temulawak extract with a concentration of 14%/kg feed, Treatment P2 Administration of temulawak extract with a concentration of 16%/kg feed, treatment P3 Administration of temulawak extract with a concentration of 18%/kg feed, and treatment P4 administration of temulawak extract with a concentration of 20%/kg feed. The results showed that in the P0 treatment the absolute weight gain was 0.78 grams, in the P1 treatment the absolute weight was 0.58 grams, the P2 treatment was 0.33 grams, the P3 treatment was 0.37 grams, and in the P4 treatment it was obtained The result of absolute weight gain was 0.39 grams. The results showed the absolute length increase ranged from 0.35-0.57 cm. It can be concluded that the addition of temulawak extract to the commercial feed of carp has no significant effect on absolute weight, absolute length, survival rate and feed efficiency level.

Goldfish is one of the most popular freshwater cultivated fish because it is one of the freshwater commodities that has economic value and is sold at a price that is affordable to all groups. Ginger is a natural ingredient that can stimulate fish growth. The purpose of this study was to determine the effect of adding ginger to feed and to determine a good dose of ginger for growth and survival rates of carp (Cyprinus carpio). This research was conducted by experimental method using completely randomized design (CRD) with 5 treatments and 3 replications. The treatments given were Treatment 1: 0 grams, without adding ginger / kg of feed (control), Treatment 2: 2.5 grams of ginger / kg of feed, Treatment 3: 5 grams of ginger rhizome / kg of feed, Treatment 4: 7.5 grams of ginger / kg of feed, Treatment 5: 10 grams of ginger / kg of feed. The results showed that the addition of ginger had no significant effect on absolute length growth, absolute weight growth, feed conversion ratio, and feed efficiency, but had a significant effect on the survival rate of goldfish (cyprinus corpio). And a good dose of ginger is in P2 treatment with a dose of 2.5 grams of ginger, because it has been able to show a good survival rate of 100%.

The use of probiotics, prebiotics and aquaculture synbiotics is widely applied to aquaculture intensification as control agents. Three species of endophytic bacteria were found, namely Bacillus sp. (1), Bacillus sp. (2), and Bacillus pumilus which is associated with anthill plants and can produce antioxidant compounds. This study aims to evaluate the growth performance of catfish fry (Pangasius sp.) given ant nest tuber extract. In this study, ant nest tuber extract was mixed into feed using the coated method in doses of 0% (A), 1% (B) and 2% (C). Fish with an initial body weight of 2.00-3.17 g were kept in three ponds with a total of 9 nets measuring 1x1x1 (m 3) (30 fish/nets), is 3 nets placed in each pond. Fish were fed treatment with three replications for 30 days. The results of this study are the average final biomass weight of catfish ranging from 8.75 to 22.17 g, in all treatments not significantly different from K. The average value of JKP, RKP, EP, LPH and Wg obtained on administration of the doses of 1% and 2% ant nest tuber extract were not significantly different for K. The highest amylase enzyme activity and feed efficiency were found in the catfish fry group that consumed feed supplementation with 1% ant nest tuber extract, each of 9.537 IU/mL. and 102.57% and the least feed consumption, namely 443.33 g. It can be concluded that the best dose of ant nest tuber extract which produces amylase enzyme activity and the highest feed efficiency is found in the catfish fry group that consumes feed supplementation with 1% ant nest tuber extract.

Tiger grouper (Epinephelus fuscoguttatus) hatchery at the household scale has contributed to the increase in national grouper seed production. The main problem in tiger grouper cultivation is the availability of superior seeds. Where superior tiger grouper seeds must have fast growth, be resistant to new environments, low FCR, have perfect morphology and be resistant to. Superior seeds of tiger grouper can be seen from the value of Survival Rate (SR), where superior seeds will have a much higher SR when maintained. The purpose of this study was to determine the Survival Rate of tiger grouper hatchery in household-scale hatcheries located on the North Coast of Bali as the main parameter and water quality as a supporting parameter. Methods of data collection is done by using 4 ways: survey, active participation, observation, and interviews. Survival rate data analysis was carried out by performing calculations based on the SR calculation formula and analyzed descriptively. The results of observations of water quality are classified as good for the value of Salinity (33-35 ppt), Temperature (28-29.4 oC), and DO (6-6.5 ppm). While the pH value can be said to be not good for tiger grouper hatchery and rearing with a pH value of (7.3-7.4). The result of the calculation of the Survival Rate is 20% with a total of ± 24,000 seeds. From the percentage of survival rate, it can be said that the survival rate of tiger grouper larvae in this household-scale hatchery is still low. However, it should be noted that a low survival rate in grouper hatcheries does not always affect the value of profits and losses of a grouper hatchery business.

Starfruit contains active ingredients such as flavonoids, phenols, antioxidants and vitamin C so that it can be used as an immunostimulant in catfish farming activities. Motile Aeromonas Septicemia (MAS) is one of the obstacles that can cause catfish farming losses. This study aims to determine the effect of differences in timing of feeding containing starfruit juice to protect catfish from MAS disease. The study was designed using a completely randomized design (CRD) consisting of 6 treatments (P) in the form of feeding duration containing starfruit for 7 days (P1), 14 days (P2), 21 days (P3), 28 days (P4). and 35 days (P5) and control of feeding without star fruit juice (P0). The research was carried out at the Aquaculture Laboratory, Sriwijya University. The dose of star fruit juice mixed in the feed is 300 mL.Kg-1 while the catfish used is 8-12 cm in size. The challenge test used Aeromonas hydrophilla bacteria with a density of 108 CFU.mL-1 which was injected as much as 0.5 mL.tail-1 intramuscularly. The results showed that administration containing starfruit juice for 28 days provided the best protection. Based on the hematological test the day before and before infection, the delta decreased the hematocrit by 3% and the delta decreased the erythrocyte count by 3,103 cells.mL-1. In addition, live feed after infection was 100%, prevalence was 17.78% and there was no effect of giving starfruit juice on growth and feed efficiency.
