Potential influence of probiotic bacteria on the growth gut microflora of Carassius auratus

Abstract

The objectives of the present study were designed to evaluate the probiotic potential of selected probiotic strains on the growth and gut microflora of Carassius auratus. Standard methods were followed for analyzing Physico-chemical parameters of experimental water. Four different probionts, such as Lactobacillus acidophilus, Lactobacillus plantarum, Lactobacillus sporogenes were incorporated with control diet to evaluate their effect on the growth performance in Carassius auratus. A maximum weight gain of 0.629 ± 0.003g was recorded in the fishes fed with L.sporogenes incorporated diet followed by L. plantarum and L. acidophilus diets. Study reveals the antagonistic effect of probiotic strains against V. parahaemolyticus as well as disease resistance and survival rate of Carassius auratus.
