摘要
The bacteria in the genus Vibrio are heterothrophic, which exist in the larval rearing water of Crustacea and often show diverse pathogenicities to marine animals. In order to assess the bacterial diversity associated with Crustacean seed production, 32 strains were isolated from black tiger shrimp (Penaeus monodon) and mangrove crab (Scylla paramamosain) larvae and their rearing-water and characterized using biochemical and molecular approaches. Two or more genotypically different species were identified. The vibriosis of black tiger shrimp was caused by V. harveyi, V. alginolyticus and Vibrio spp. predominantly, while that of crab by V. harveyi and V. alginolyticus only.
