Ontogenetic Changes in the Digestive Capacities of the Naozhou Stock of Large Yellow Croaker (<i>Larimichthys crocea</i>).

ABSTRACT: This study examined the digestive and metabolic responses of Naozhou (NZ) stock large yellow croaker (Larimichthys crocea) larvae and juveniles under five developmental feeding stages (DAH3, DAH7, DAH12, DAH19, DAH49) to clarify mechanisms of early nutritional adaptation. Digestive enzyme assays, transcriptome sequencing, and metabolomics were integrated to compare physiological changes across diets. Protease activity increased sharply from DAH7-19 with the introduction of rotifers, Artemia, and copepods, while amylase and lipase activities rose at DAH19-49, reflecting enhanced carbohydrate and lipid utilization during transition to formulated feeds. Transcriptomic analysis showed that differentially expressed genes were enriched in pathways involving protein digestion, lipid and en
