Abstract: The dynamics of some main ba - necked clam （Ruditapes philipinarum） cterial groups were investigated in deposition and sand filter pool for short breeding in Zhuanghe county, Dalian, Liaoning province in 2005. There were no significant differences in numbers of heterotrophic bacteria, Vibrio, ammonifying bacteria, and ammonium - oxidizing bacteria in the sand filter pool exit and in the deposition pool exit. The less bacteria groups were found in water column than in sedimentation. Either in water or in mud, however, the maximal heterotrophic bacteria and Vibrio were separately observed in the end of April and May. The ammonium - oxidizing bacteria were set separately in water column in July to August and in sedimentation in August to September, and ammonifying bacteria were obtained separately in August to September in water column and in sedimentation in September to October. Denitrifying bacteria and desulphurizing bacteria were obtained in sedimentation from June to September. The water quality of deposition pool was found to be eutrophication.
