Effects of probiotic treatment on the intestinal microbial community of Haliotis diversicolor.

ABSTRACT: Probiotic treatment is an effective method for enhancing growth performance and improving intestinal flora in aquaculture species. This study examined the effects of three candidate-probiotics (Bacillus, photosynthetic bacteria, and Lactobacillus) on the rate of weight gain and the intestinal flora of abalone juveniles. Haliotis diversicolor was fed a probiotic-supplemented diet for 30 days. The abalones fed with Lactobacillus showed a more significant weight gain rate than those in the Bacillus, photosynthetic bacteria, and control groups. Through 16S rRNA high-throughput sequencing, 12,490 amplicon sequence variants (ASVs) were obtained from the abalone intestinal tract microbiome. After a short feeding period (5 days), the Bacillus and photosynthetic bacteria-treated groups showed an in
