Spawning in the aquaculture of giant gourami is an important factor which determines the success of production because it supports the sustainability and improvement of the quality and quantity of giant gourami fry in aquaculture activities. The purpose of this study was to evaluate the feeding in the conditioning of giant gourami (Osphronemus gouramy) broodstock. The methodology carried out included the preparation of spawning ponds, broodstock selection, broodstock feeding, spawning, conditioning, nest inspection and egg collection, egg handling, egg hatching, and larval rearing. The eggs produced were 21.452 eggs with 18.714 fertilized eggs and 2,738 unfertilized eggs, and the Fertilization Rate (FR) value obtained during the study was 87.3%. Eggs that successfully hatched into larvae were as many as 16.238 while eggs that did not hatch were as many as 2.341 eggs, and the Hatching Rate (HR) value obtained was 87%. The water quality data obtained from the broodstock pond and the hatching pond included DO with a range of 5.88 – 6.11 mg/L, a temperature of 27.2°C – 28.2°C, and a pH ranging from 7.21 to 7.27.

HighlightsLitopenaeus vannamei has been established as alternative to Penaeus monodon to shrimp farming in several countries.Increased importance of in situ microorganisms both in regulating biogeochemical cycles within the culture environment and in directly affecting shrimp growth and survival.To improve water quality in aquaculture is the application of probiotics and/or enzymes to ponds. AbstractIntensive shrimp farming has raised environmental issues due to aquaculture pollution, which is caused by uneaten feed, feces, organic matter, and toxic compounds (ammonia and H2S). One way to solve this issue is by using probiotics. Thus, this study aimed at investigating the effect of probiotic administration (Pseudomonas sp. and Bacillus sp.) at varying concentrations on total organic matter in the rearing water, feed conversion ratio, feed efficiency, and growth rate of white shrimp (Litopenaeus vannamei). This study used a Completely Randomized Design consisting of four treatments: T0 (without the probiotic supplementations), T1 (probiotics at 106 CFU/ml), T2 (probiotics at 107 CFU/mL), T3 (probiotics at 108 CFU/mL) with three replicates each. The results showed that the administration of probiotics at different concentrations had a significant effect on the total amount of organic matter, feed conversion ratio, feed efficiency, and specific growth rate of white shrimp. Administration of probiotics at a concentration of 107 CFU/ ml had the lowest organic matter in the rearing water, 138 mg /Lt. While probiotic administration at 108 CFU/ ml gave the lowest feed conversion ratio (1.22), the highest feed efficiency (81.57%) and the best growth rate (2.25%/day). This research suggests that the administration of 107-108 CFU/ ml probiotics could be applied to reduce organic content in the rearing water and improve the growth performances of white shrimp.

Disease motile aeromonas septicemia (MAS) caused by the bacterium A. hydhrophilla, is a disease that can affect all species of freshwater fish in the tropics. The use of antibiotics for the treatment of bacterial diseases have long been used, but the use of antibiotics that are not controlled pathogens causing bacterial resistance. The purpose of this study to determine the effect and the optimum concentration of the mahkota dewa leaf extract against bacteria A. hydhrophilla. The treatment in this study was the addition of the mahkota dewa leaf extract and DMSO with a variant concentration of 100 mg, 140 mg, 180 mg, 220 mg, 260 mg, positive control using antibiotics chloramphenicol and negative controls using DMSO. Research of mahkota dewa leaf extracts to inhibit the growth of Aeromonas hydrhopilla. This is indicated resources by the formation of an inhibition zone at all concentrations. The formation of inhibition zone of the mahkota dewa against A. hydhrophilla leaf extract shows that the mahkota dewa leaf extract can inhibit the growth of bacteria.
