Effects of dietary protein level on reproductive performance, transcriptomics and metabolomics of ovaries of female northern snakehead (<i>Channa argus</i>) broodstock.

ABSTRACT: The study investigated the effects of dietary protein levels on reproductive performance, egg quality, and larval health of the northern snakehead (Channa argus) broodstocks. A total of 450 female northern snakeheads (16 months old), averaging 731.49 ± 3.51 g, were randomly distributed into 15 cement pools, with each pool containing 30 fish. Five isolipidic diets comprising 34%, 38%, 42%, 46%, and 50% crude protein (labeled as CAP34, CAP38, CAP42, CAP46, and CAP50) were formulated and fed to experimental fish for 4 months. The results showed that the fertilization rates of northern snakehead broodstock in the CAP42 and CAP46 groups were significantly higher than those in other groups (P = 0.049). The optimal dietary protein levels for northern snakehead broodstock were 41% an
