Abstract

Effect of manipulation of dietary rotifer Brachionus plicatilis bacterial flora on the intestinal bacterial flora of Japanese flounder Paralichthys olivaceus larvae was investigated. Manipulation was done by disinfecting rotifer eggs to reduce viable bacterial counts and then by inoculating hatched rotifers with non-sucrose fermenting Vibrio splendidus strain V-15 to make the bacterium dominant in the rotifers. Flounder larvae were fed the manipulated rotifers and intestinal bacterial flora of the fish was monitored. The dominant intestinal bacterial flora of the flounder became Vibrio spp. These results indicate that intestinal bacterial flora of flounder can be artificially controlled by manipulating bacterial flora in diets.
