Effects of amino acids on olfactory‐related receptors regulating appetite in silver pomfret

Silver pomfret (Pampus argenteus) performs a significant appetite for jellyfish, and amino acids are common components of the natural prey fish, so we investigated effect aspartic acid, glycine cysteine (high-content acid in jellyfish) on olfactory-related receptors regulating silver pomfret. The fish showed attractant responses to these water, which were also observed improve ingestion rates fish. Next, conducted transcriptomes olfactory epithelium (OE) identified 34 receptor genes including receptors, trace amine-associated vomeronasal genes, examined OE appetite-related (ghrelin leptin gut/stomach neuropeptide Y, agouti-related protein proopiomelanocortin brain) by qRT-PCR. significantly expressed groups, expression level was highest group. Thus, induced might regulate through OE–brain–gut stomach axis. Using data, some effective phagostimulants could be supplied diet, results improved our understanding mechanism
