Identification of Pathogenic Bacteria in Tilapia Fish (<i>Oreochromis niloticus</i>) Cultivated in Concrete Ponds in the Palangka Raya Area

Abstract This research aims to identify pathogenic bacteria found in Tilapia fish seeds ( Oreochromis niloticus ) cultivated in concrete ponds in the Palangka Raya area. To identify the type of bacteria, use the book Cowan and Steel’s Manual for The Identification of Medical Bacteria 1974. This research was carried out by taking samples of tilapia seeds from 3 different cultivator ponds. And then testing was carried out at the Fish Quarantine Station Laboratory, Fishery Quality Control and Fishery Product Safety (SKIPM) Palangka Raya. This research was carried out in May 2024. This research method is descriptive by taking samples of fish seeds, sterilizing tools and materials, measuring water quality parameters, isolating bacteria, and identifying bacteria. The research results showed that the bacteria found were 6 (six) genera of bacteria, namely Acinetobacter sp., Actinobacillus sp., Aeromonas sp., Micrococcus sp., Moraxella sp. and Pasteurella sp.
