Resumo: | The quantitative and qualitative evolution of the heterotrophic bacterial community of sea water was studied throughout an experimental rearing of Penaeus japonicus in closed systems. Cluster analysis was realised on 417 strains coming from water sampled at different moments of the experiment. This collection includes 40 strains coming from a mussel used for diet and 40 strains coming from the digestive tract of one prawn after six months rearing. Quantitative and qualitative studies have both shown a similar evolution of heterotrophic microflora whatever the initial animal load was. The dendrogram obtained led to a description of characteristics of the various populations constituting the heterotrophic bacterial community of the water environment considering the increasing number of bacteria brought in the system by breeding activities.
