Transcriptomic Analysis Reveals Glycolysis and Gluconeogenesis Pathway Activation Underlying Growth Enhancement by Duck-Blood Protein Hydrolysate in Flowerhorn Cichlid Fish.

ABSTRACT: Protein hydrolysates have potential as sustainable functional feed ingredients or additives for the aquaculture industry. This study examined the growth-promoting effects of duck-blood protein hydrolysate (DBPH, <10 kDa) on the flowerhorn cichlid (Amphilophus citrinellus × Cichlasoma trimaculatum). Fish with an average weight of 3.24 ± 0.22 g were randomly assigned to four dietary treatments: a negative control (basal diet) and basal diets supplemented with 0.5%, 1%, and 2% DBPH. After 90 days of the feeding trial, growth parameters indicated that supplementation with 1% and 2% DBPH enhanced growth. However, the muscle composition and skin coloration did not differ significantly. Transcriptome sequencing of the liver tissue yielded 39.83 GB of high-quality clean data. De novo
