TABLE 2.
Effective Tags, abundance, and alpha diversity index of the gut microbiota in each Siniperca chuatsi group. ACE: estimated number of OTUs contained in the microbiota; Chao1: estimated total number of species contained in the microbiota samples; Simpson’s index: characterize the diversity and homogeneity of species distribution within the microbiota, this study used Simpson’s index of diversity (1–D).
