This study is to explore the alleviating effects of glutamate on intestinal damage in cultured little yellow croaker. A total 900 juvenile fish at a weight 30.68 ± 0.12 g were randomly separated into six groups with three replicates each, and fed basic diet (protein 44.42% lipid 12.48%) additional 0.00%, 0.40%, 0.80%, 1.2%, 1.60%, 2.00%. Each replica group consisted 50 breeding barrel (radius 1.0 m, height 1.5 m), experiment lasted for 54 days. The results showed that supplementation 0.4–1.2% significantly improved survival rate, which increased from 75.56% 91.11%, reduced feed conversion rate 1.75 1.57, protein efficiency ratio 1.55 1.85 (p < 0.05). In intestines, addition 0.40–1.2% muscle thickness villus 0.05), as well activities pepsin, trypsin, α-amylase, lipase Enzyme activity analysis indicated enhanced serum Total Superoxide Dismutase (T-SOD), catalase (CAT), glutathione peroxidase (GPx) antioxidant enzymes Transcriptome 1.2% 0% revealed differentially expressed genes enriched synthesis, nutrient absorption metabolism, viral interaction cytokine receptor pathways. qPCR experiments verified up-regulated expression antioxidant-related genes, including synthetase Nrf2. conclusion, can enhance growth performance, increase digestive capacity, activate synthesis alleviate damage, maintain health.
