Microbiome of Finfish and Shellfish

Abstract

The microbiome is a complex yet defined set of microbial species in a given habitat. The mining of the human microbiome is pursued in several research projects globally. The microbiota of other vertebrate animals also needs to be studied. Fish represent a diverse group of vertebrates and are the primary source of animal protein. The fish gut microbiota plays a crucial role in the host’s metabolism and can be manipulated to maximize production. Similar to humans, the fish microbiota is studied using culture-dependent and culture-independent techniques, including next-generation sequencing, bioinformatics analysis, and omics. Various fish organs have been examined for their dominant and distinctive microbiota species, including the gills, skin, gut, kidney, liver, and spleen. Under various environmental, dietary, and other physiological situations, the gut microbiota is explored. Gnotobiotic zebrafish represent a valuable model for studying microbe–microbe and microbe–host interactions. Microbe–microbe interactions can be modulated by pre-, pro, and synbiotics, influencing the development of the fish immune system, which will eventually reduce the need for antibiotics. This chapter highlights the necessity of research to advance knowledge of fish health, immune system, metabolism, probiotic research, etc., and to extract novel biomolecules with functional features for creating new medications and pharmaceuticals.
