Abstract
Qualitative and quantitative investigation was carried out on the intestinalmicroflora of the common carp in freshwater culture ponds.Ten kinds of normal bacte-ria were inoculated on various selective media,including Aeromonas,Pseudomonas,Escherichia coli,Staphylo coccus,Bacillus,Saccharomycete,Lactobacillus,Bifidobacterium,Bacteriodes and Clostridium. The result showed that the predominattaxa of nonnal microflora in the intestine of carp are Bacteriodes,Aeromonas and Saccharomvcete. There were significant differences in the numbers of Staphylococcus and Pseudomonas at different times and temperatures(p0.05).No significant differencewas found in the numbers of the other eight kinds of nonnal microflora at different timesand tempratures(p0.05).
