- Shrimpis one of the sources ofhighquality protein, shrimp isexcellentforIndonesiannon-oil exports. Heightenedshrimp farming, it will not beseparated fromthe shrimpcrop failure , thecause isone ofthewell-knownshrimpdiseasebacteriumVibriospisacauseof diseasevibriosisThis research was conducted from July to August 2010 with the purpose to know the level pathogenitas and early symptoms are caused by bacteria in the Vibrio sp on tiger prawns. Vibrio sppathogenitas tests conducted at the Brackishwater Aquaculture Development Centre (BBPBAP) Jepara.The results showed that all species of Vibrio sp (V. harveyii, V.alginolyticus, V. vulnificus, V. anguilarum, V. parahaemolyticus) are pathogens tested, it is characterized by the occurrence of death in tiger shrimp larvae in all treatments. The death of the infected shrimp larvae at densities of bacteria Vibrio sp 10 4 CFU/ml respectively are 3.3%, 6.7%, 6.7%, 36.7%, then increase the mortality of shrimp with the concentration of bacteria suspended in a row 55%, 68.3%, 73.3%, 81.7% and 100% with aconcentration of 10 7 bacteria CFU/ml. The higher the concentration of bacteria that infected a longperiod of immersion and comparable with pathogenitas bacterium Vibrio sp that causes mortality ofshrimp larvae is higher. Vibrio harveyi is a bacterium with Pathogenicity highest level of the other. Clinical symptoms were found among other shrimp do not swim regularly to jump surface and poor appetite or decreased.
