Impact of Exogenous Glutamine on Growth-Related Gene Expression and Metabolic Pathways in Trachinotus blochii

In recent years, the scale of Trachinotus blochii aquaculture has been expanding. Our previous research identified glutamine metabolism related genes as key regulators of T. blochii growth. Recently, fish essential amino acids have been developed as nutritional additives in aquaculture feed. To explore the effects of glutamine on growth related genes in T. blochii, we used a commercial feed without glutamine as the control, alongside four experimental groups supplemented with 0.3%, 0.6%, 0.9%, and 1.2% glutamine
