Abstract

Aquaculture is considered as one of the fastest growing, efficient and diverse animal protein production sectors globally. With the expansion of aquaculture industry, use of intensive culture methods and introduction of exotic species have greatly increased that have led to the incidence and severity of disease outburst among culturable aquatic species. Considering the role of gut microbiota in digestion, metabolism, health and immunity, modulation of gut microbiota could be a worthwhile control management strategies to counteract reported and emerging pathogens in aquaculture and hence to curb the enormous economic losses. In order to promote sustainable aquaculture and to mitigate the stress mediated through diseases, current knowledge on gut microbiota focusing beneficial and potential pathogens and impacts of gut microbial dysbiosis needs to be extended to generate species-specific gut microbial resources that are linked to modulation of key immune responses and metabolic pathways. Although the databases for environmental DNA (eDNA) and pipelines for the prediction of metagenomic functions of gut microbiota are limited for fishes, however foundational informations are being updated more frequently in recent times to identify core and precise bacteria and evaluating their role in gut health and immune responses. Furthermore, advancement in computer programming and data analysis packages have widen the opportunity to identify the link between diseases and particular taxa, indicator or marker bacteria for species specific disease diagnosis and treatments.
