Studies of gut microbial communities on Takifugu obscurus between sexes

Gut microbiota plays an important role in fish nutrition, immunity, development and beyond, and the assemblages and dynamics of fish gut bacterial community can be influenced by a multitude of biotic and antibiotic factors. To explore how and to what extent does fish sex influence the structure and function of gut microbiota, we sexed the cultured sub-adult Takifugu obscurus with differed gonadal development stage and analyzed the sex-biased gut bacterial community via 16S rRNA amplicon sequencing.
