| Summary: | Fish gut microbiome confers various effects to the host fish; this includes overall
size, metabolism, feeding behaviour and immune response in the fish. The emergence
of antimicrobial-resistant (AMR) bacteria and hard to cure fish diseases
warrant the possible utilization of gut microbes that exhibits a positive effect on
the fish and thus lead to the usage of these microbes as probiotics. The
widespread and systematic use of antibiotics has led to severe biological and ecological
problems, especially the development of antibiotic resistance that affects
the gut microbiota of aquatic organisms. Probiotics are proposed as an effective
and environmentally friendly alternative to antibiotics, known as beneficial
microbes. At the same time, prebiotics are considered beneficial to the host’s
health and growth by decreasing the prevalence of intestinal pathogens and/or
changing the development of bacterial metabolites related to health. Uprise of
sequencing technology and the development of intricate bioinformatics tools has
provided a way to study these gut microbes through metagenomic analysis. From
various metagenomic studies, ample of information was obtained; such information
includes the effect of the gut microbiome on the physiology of fish, gut
microbe composition of different fish, factors affecting the gut microbial composition
of the fish and the immunological effect of gut microbes in fish; such this
information related to the fish gut microbiome, their function and their importance
in aquaculture is discussed in this review. |
