Identification Of Pathogenic Bacteria In Tilapia (Oreochromis niloticus) on Lombok Island

Abstract

Tilapia (Oreochromis niloticus) is one type of freshwater fish that has high economic value so it is widely cultivated. The problem of disease in fish is a major obstacle because it can harm aquaculture such as decreased production, decreased water quality and even total death. Diseases can be caused by several types of pathogens such as viruses, parasites, fungi and bacteria. In this study, identification of pathogenic bacteria in tilapia (Oreochromis niloticus) on Lombok Island was carried out. Sampling was carried out in five regencies including East Lombok Regency, Central Lombok Regency, West Lombok Regency, Mataram City, and North Lombok Regency, each district four fish samples were taken in two different ponds and then immediately checked the water quality such as temperature, pH, ammonia, and do. Sampling was done by selecting sick tilapia and morphologically healthy tilapia. In this study found types of bacteria from the genus Aeromonas sp, namely Aeromonas hydrophila, Aeromonas veronii, and Aeromonas sobria.
