Abstract：An investigation on the diversity of bacterial organisms in hepatopanueas ,spleen and kidney of healthy hybridized crussian carp (Carassius auratus gibelio) was carried out in six large‐scale breeding farms in Zhejiang province during June —July and September—October in 2013 .From a total of 12 bat‐ches ,seven opportunistic bacterial species capable of affecting humans ,animals and fishes were identified . A eromonas spp .predominated both in June—July and September—October batches and aerA +act+alt‐act‐was the major virulence‐gene pattern ,indicating that the Aeromonas isolates exhibited potential pathogenic inclination .On the contrary ,Acinetobacter lwof fii ,Edwardsiella hoshinae ,Plesiomonas shigelloides , Shewanella putref aciens , Stenotrophomonas maltophilia and Escherichia coli showed varying isolation rates between June—July and September—October batches .Bacterial species composition and high carry‐ing‐rate of pathogenic A eromonas in hybridized prussian carp posed significant risks to aquaculture industry and public health .It is necessary to develop the surveillance system of potential bacterial pathogens ,espe‐cially A eromonas spp .,in hybridized crussian carp ,and to clarify the pathogenic mechanism to establish comprehensive prevention and control schemes .
