Abstract

Vibrio is a group of bacteria that causes biota of water that is cultivated in ponds death. This research aims to determine the type of bacteria Vibrio sp. which causes the disease in white snapper fish in the ponds BBPBL Lampung. The research method is exploration method by isolating Vibrio bacteria from the organ in white snapper, mud, and water and identifying bacterial isolate characteristics with biochemical test. Besides, water quality examination of pond to temperature, pH, salinity, DO, BOD and ammonia and calculation of ALT (Total Plate Number) Vibrio sp. on the pond. Based on the results of the research, three types of isolates are suspected as the cause of disease in white snapper fish in Lampung BBPBL pond, namely Vibrio vulnificus, Vibrio alginolyticus and Vibrio parahaemolyticus. The three isolates obtained were known to be α-hemolysis. The results of pond water quality inspection showed the temperature of 29.8 oC, pH 7.8, salinity 33 psu, DO 4.4 mg / L, BOD 2.2 mg / L and ammonia 2.2 mg / L. Calculation of ALT Bacteria Vibrio sp. shows inlet of pond <25 CFU / ml, pond water 7.6x104 CFU / ml, and pond water outlet 2.1x103 CFU / ml. Levels of ammonia and calculation of ALT Bacteria Vibrio sp. exceeds pond water quality standards for fish farming.
