The Journal of Fish Health (JFH) has an objective to publish and provide high-quality scientific contributions to the field of fish health. These contributions are sourced from innovative research that encourages science and technology development in the field of fish health on a national and international scale. This journal serves as a communication medium for researchers, academics, students, and communities. This journal is published two times a year in June and December. We accept review papers and full research articles. The Journal of Fish Health’s scope includes:  1. Fish Pharmaceutical 2. Fish Environmental Health 3. Microbiology 4. Biotechnology 5. Parasitology, etc. 6. Aquaculture 7. Management of Water Resources 8. Fishery Technology 9. Capture Fisheries Technology 10. Marine Science and Technology 11. Fisheries Agribusiness The Journal of Fish Health (JFH) accepts manuscripts written in English and Bahasa (Indonesian). The Journal of Fish Health (JFH) only processes submitted original script related to the scope of fish health and not being published by other publishers. The Journal of Fish Health (JFH) is jointly published by the Department of Aquaculture, Faculty of Agriculture, Mataram University.

Abstract

Whiteleg shrimp (Litopenaeus vannamei) is a leading aquaculture commodity with high economic value and can be farmed intensively with high stocking density. Intensive farming systems have the potential to increase the accumulation of organic matter and metabolic waste, which can trigger the growth of pathogenic bacteria such as Vibrio sp. The presence of these bacteria can cause health disturbances in shrimp and reduce survival rates. The purpose of this study is to determine and test the effectiveness of probiotics in suppressing the population of Vibrio sp. in whiteleg shrimp (Litopenaeus vannamei) farming. Data collection methods were carried out primarily and secondarily through direct observation, interviews, active participation in the field, documentation, and literature studies. Control techniques were performed through several stages, namely pond preparation, probiotic culture using molasses and skim milk, mixing probiotics into feed, application of probiotics to ponds. as well as routine monitoring of water quality. The observed parameters include nitrate (NO₃), nitrite (NO₂), ammonium (NH₄), phosphate (PO₄), alkalinity, Total Organic Matter (TOM), and the total population of Vibrio sp. The results of the study showed that the application of commercial probiotics was effective in suppressing the growth of Vibrio sp. with a population density of 103-104 CFU/ml during cultivation through the mechanisms of nutrient competition and the production of antibacterial compounds, as well as helping to maintain the stability of pond water quality within the optimal range for shrimp growth.

Abstract

A common problem faced by betta fish breeders during the hatchery stage is the low survival rate of fry, as they are highly susceptible to changes in water quality and disease. Therefore, fry management is necessary to increase survival rates by using natural ingredients that are environmentally friendly and do not cause resistance. Ketapang leaves (Terminalia catappa) and betel leaves (Piper betle) can be used because they contain active compounds such as flavonoids, which have antimicrobial properties that can help inhibit the growth of bacteria and fungi in the water. The aim of this study was to determine the appropriate dosage of ketapang leaves and betel leaves for the survival rate of betta fry. This study used an experimental method, namely RAL with 4 treatments and 3 replications, the treatments tested were P0 (control): no treatment, P1: 1 g/l ketapang leaves, P2: 1 g/l betel leaves, P3: 0.5 g/l ketapang leaves and 0.5 g/l betel leaves. The parameters tested included absolute weight, absolute length, specific weight growth, daily length growth and survival rate. The results showed that the average absolute weight of betta fish ranged from 0.193-0.444 g, the average absolute length ranged from 2.379-3.021 cm, the average specific growth rate ranged from 0.015-0.006%/day, the average daily growth rate ranged from 0.034-0.019%/day, and the average survival rate ranged from 60.00-13.33%.
