  • Intensive aquaculture has increased the severity and frequency of fish diseases. Given the functional importance of gut microbiota in various facets of host physiology, modulation of this microbiota is a feasible strategy to mitigate emerging diseases in aquaculture. To achieve this, a fundamental understanding of the interplay among fish health, microbiota, and invading pathogens is required. This mini-review focuses on current knowledge regarding the associations between fish diseases, dysbiosis of gut microbiota, and immune responses. Furthermore, updated research on fish disease from an ecological perspective is discussed, including colonization resistance imposed by commensals and strategies used by pathogens to overcome resistance. We also propose several directions for future research, such as exploration of the causal links between fish diseases and specific taxa, and identification of universal gut microbial biomarkers for rapid disease diagnosis.

Abstract: Intensive aquaculture has increased the severity and frequency of fish diseases. Given the functional importance of gut microbiota in various facets of host physiology, modulation of this microbiota is a feasible strategy to mitigate emerging diseases in aquaculture. To achieve this, a fundamental understanding of the interplay among fish health, microbiota, and invading pathogens is required. This mini-review focuses on current knowledge regarding the associations between fish diseases, dysbiosis of gut microbiota, and immune responses. Furthermore, updated research on fish disease from an ecological perspective is discussed, including colonization resistance imposed by commensals and strategies used by pathogens to overcome resistance. We also propose several directions for future research, such as exploration of the causal links between fish diseases and specific taxa, and identification of universal gut microbial biomarkers for rapid disease diagnosis.
