    Analysis of the fecal microbiota of fast- and slow-growing rainbow trout (Oncorhynchus mykiss)
    (Springer Nature, 2019-10-29) Chapagain, Pratima; Arivett, Brock; Cleveland, Beth M.; Walker, Donald M.; Salem, Mohamed
    Diverse microbial communities colonizing the intestine of fish contribute to their growth, digestion, nutrition, and immune function. We hypothesized that fecal samples representing the gut microbiota of rainbow trout could be associated with differential growth rates observed in fish breeding programs. If true, harnessing the functionality of this microbiota can improve the profitability of aquaculture. The first objective of this study was to test this hypothesis if gut microbiota is associated with fish growth rate (body weight). Four full-sibling families were stocked in the same tank and fed an identical diet. Two fast-growing and two slow-growing fish were selected from each family for 16S rRNA microbiota profiling.
