Dynamic impacts of stock enhancement on wild Amur sturgeon (Acipenser schrenkii): New protection insight into intestinal microbe and gene expression mode

On October 9th,2023, one thousand Amur sturgeon with similar genetic background were released to Songhua River after artificial breeding in Harbin. Before re-wilding to river,they were bred in the net cages. To explore whether feeding Limnodrilus before stock enhancement would affect the gene expression mode, we set two groups, one group was fed with commerial feed , another was fed with fresh Limnodrilus. After 30 d breeding, we collected the gut samples to perform transcriptome sequencing project.

Before re-wilding to river,they were bred in the net cages. To explore whether feeding Limnodrilus before stock enhancement would affect the gene expression mode, we set two groups, one group was fed with commerial feed (Q), another was fed with fresh Limnodrilus (H). After 30 d breeding process, we collected the gut samples to perform transcriptome sequencing project.In addition, Limnodrilus was bred in the fish-breeding water source to allow Limnodrilus to carrry the environmental microbe.
