Analysis of intestinal microbiota of the kuruma shrimp Penaeus japonicus in different rearing models
This study proposes a novel sand-free culture method for heat-tolerant Penaeus japonicus. During the high-temperature period, a comparative culture experiment was conducted under both sand-based and sand-free conditions. At the end of the experiment, shrimp reared in the sand-free system exhibited lower mortality and faster growth rates compared to those reared with sand. Following the experiment, samples were collected for subsequent analysis from the intestinal microbiota of shrimp, the water microbial communities under both culture conditions, and the sediment microbiota from the sand-based system.
