Gut bacterial community of Penaeus vannamei (PRJCA045740)
Intensive shrimp aquaculture has led to the excessive accumulation of nitrite, resulting in shrimp mortality and posing a widespread challenge to aquaculture systems. In this study, we analyzed the gut bacterial communities of shrimp that either survived or died after exposure to a semi-lethal concentration of nitrite for 72 hours. We isolated 17 bacterial strains to construct a potential endogenous probiotic consortium, which significantly enhanced shrimp survival under acute nitrite stress. This study provides novel insights and strategies for mitigating environmental stress in shrimp aquaculture.
