| contents | Probiotic-driven microbiome remodeling is associated with coordinated immune and metabolic responses, improving growth and disease resistance in farmed tongue sole (). Hu, Yuanri Yan, Xu Gao, Fengtao Xu, Dan Yang, Yingming Cheng, Jiayu Chen, Songlin Cui, Zhongkai In flatfish aquaculture, labour-intensive tank cleaning represents a major operational challenge, limiting sustainability due to its high labour requirements and associated costs. We tested a new semi-closed recirculating aquaculture system (RAS) protocol for (tongue sole), replacing manual cleaning with post-feeding water exchange (80% drained) and probiotic application. Compared with control groups, the probiotic-water exchange protocol significantly improved growth (+0.18%/day) and survival (+7.9%), while shifting the gut microbiota from a -dominated configuration to a -dominated one. Metagenomics revealed that became the predominant taxon (86%) in the probiotic group, accompanied by the enrichment of quorum sensing pathways, CAZymes (CEs, AAs), and nutrient metabolism functions. Histological examination showed improvements in the intestinal muscular layer and villi structure. Multi-tissue transcriptomics identified systemic changes in immune and metabolic pathways, including activation of intestinal immune networks (IgA production, NF-κB signaling) and antimicrobial peptide genes. Liver, gill, and skin transcriptomes revealed enhanced DNA repair, cytokine signaling, and barrier pathways. JAK-STAT pathway was also activated, linking microbial metabolite sensing to growth promotion (). The probiotic-integrated protocol modifies the gut microbiome by shifting microbial composition through changes in competitive interactions and microbial signaling pathways. It also improves the intestinal wall, overall immunity, and nutrient absorption. These findings provide insights into the microbiome-host interaction under probiotic treatment and suggest that this strategy may offer potential benefits under farm conditions, but further studies are needed to validate its safety and ecological implications. |
