Resilience and probiotic interventions to prevent and recover from shrimp gut dysbiosis

To counter the recurrent outbreaks of bacterial (acute hepatopancreatic necrosis disease; AHPND) and viral (white spot disease; WSD) shrimp diseases, which still remain a threat to the global industry, shrimp gut microbiota research has been gaining more attention in recent years, and the use of probiotics in aquaculture has had promising results in improving shrimp gut health and immunity. In this review based on our studies on AHPND and WSD, we summarize our current understanding of the shrimp gastrointestinal tract and the role of the microbiota in disease, as well as effects of probiotics. We focus particularly on the concept of microbiota resilience, and consider strategies that can be used to restore shrimp gut health by probiotic intervention at a crucial time during gut microbiota dysbiosis. Based on the available scientific evidence, we argue that the use of probiotics potentially has an important role in controlling disease in shrimp aquaculture.

Automated summary

In order to face the recurring outbreaks of bacterial and viral shrimp diseases, shrimp gut microbiota research and probiotic intervention have shown promising results in improving shrimp gut health and controlling disease in shrimp aquaculture. This review summarizes the current understanding of the shrimp gastrointestinal tract, the role of microbiota in disease, and the effects of probiotics based on studies on acute hepatopancreatic necrosis disease and white spot disease. The concept of microbiota resilience and strategies for restoring shrimp gut health through probiotics are also discussed.
