Effects of Diet on the Gut Microbial Communities of Nile Tilapia (Oreochromis niloticus) Across Their Different Life Stages

Nile tilapia ( Oreochromis niloticus ) is one of the most important commercial freshwater fish in China, and dietary transition occurs their different life stages. The gut microbiota to host health. relationships among diet, microbiota, development are not well known. In present study, we attempted understand how diet associated with community dynamics during tilapia. first experiment was performed under standard laboratory feeding operation determine effect on intestinal microbiota. second experiment, were fed Artemia or plant-based dry (PBD) food from started late juvenile stage (90 days post-fertilization). results showed that habit had a low intestine. negatively affected survival rate phylum Planctomycetes dominant PBD food. Fusobacteria Artemia. At genus level, Gemmobacter , Pirellula Planctomyces belonging Planctomycetes, significantly abundant guts diet. Cetobacterium Thus, can conclude types have great intestine early microflora established tilapia, approximately 2 months after hatching. Our provide useful information for experimental design studies microbial gut. We suggest modulation could be life.
