“…More recently, high‐throughput sequencing of 16S rRNA gene amplicons has been used to explore the diversity and composition of gut microbiota in fish species, including three‐spined stickleback and Eurasian perch (Bolnick et al ., ), fathead minnows (Narrowe et al ., ), surgeonfishes (Miyake et al ., ), Trinidadian guppies (Sullam et al ., ), tilapia (Giatsis et al ., ), Atlantic cod (Forberg et al ., ), Atlantic salmon (Llewellyn et al ., ) and some commercially viable cyprinids (Eichmiller et al ., ; Liu et al ., ). Most of these fishes were studied in the rearing conditions fed basic diet or in wild conditions, which well demonstrated the influence of basic dietary input and environmental locations on the gut microbiota.…”
