Effects of lactobacillus plantarum, pediocococcus pentosaceus, and lactobacillus fermentum supplemented diet on survival rate, resistance to vibrio spp. and to acute hepatopancreatic necrosis disease (ahpnd) in white leg shrimp (litopenaeus vannamei).

The experiment was conducted to determine the effects of L. plantarum, P. pentosaceus, and L. fermentum supplemented diet on survival, resistance to AHPND in white leg shrimp. The experimental results showed that the density of Vibrio spp. in the gut lumen of shrimp was significant decreased during the experimental period in the treatments of which the lactic acid bacteria (LAB) used as supplemented diet and without challenged with Vibrio parahaemolyticus. | Effects of lactobacillus plantarum, pediocococcus pentosaceus, and lactobacillus fermentum supplemented diet on survival rate, resistance to vibrio spp. and to acute hepatopancreatic necrosis disease (ahpnd) in white leg shrimp (litopenaeus vannamei).

The experimental results showed that the density Keywords: of Vibrio spp. in the gut lumen of shrimp was significant decreased during the AHPND, Litopenaeus experimental period in the treatments of which the lactic acid bacteria (LAB) vannamei, white leg shrimp, used as supplemented diet and without challenged with Vibrio Vibrio spp, Vibrio parahaemolyticus. The survival rate of shrimp was very high (88,9-92,23%) in parahaemolyticus. these treatments. In addition, hepatopancreas tissues of shrimp did not have the typical symptoms of AHPND. In the treatments that the shrimps were challenged to V. parahaemolyticus, the survival rate of the shrimps was significant increased to (79,8%) and (75,8%) when L. plantarum, and P. pentosaceus, respectively, were supplemented into the diet of the shrimps. The density of Vibrio spp. in the gut lumen of the shrimps was also significant decreased during the experimental period. The .
