Studies on the Composition of Intestinal Bacterial Flora of Acipenser schrenckii and Huso dauricus Bred under Artificial Conditions

ABSTRACT

The composition of the communities of cultivated heterotrophic bacteria of the intestinal tract of Acipenser schrenckii and Huso dauricus bred under artificial conditions has been studied for the first time. Under similar conditions of occurrence, the studied specimens of fish essentially differed in the composition of intestinal bacterial flora. It has been found that in ill specimens the taxonomic diversity of intestinal microbiota was significantly lower than that registered in healthy specimens. It has been shown that the intestinal microflora is formed selectively at the expense of the microflora of the water.
