This study investigated the impacts of various inclusion levels of dietary potential of fish protein hydrolysate (FPH) on the growth and reproductive performance, biochemical composition, blood parameters, and liver histology of Ompok pabda broodstock. About 600 pabda broods (11.00 ± 0.05 g) were distributed into 12 cages and fed twice in a day. For this, four experimental diets (crude protein: 30%; crude lipid: 9%) were prepared by incorporating FPH at different percentages (0%, 5%, 7%, and 9%). The FPH positively impacted (p < 0.05) the durability index, water stability, and swelling rates of the experimental diets. Furthermore, significantly higher palatability (p < 0.05) was recorded for pabda diets incorporated with 5% and 7% FPH. After 90 days, the growth performance of pabda in final weight, live weight gain, total biomass, specific growth rate, hepatosomatic index, visceral somatic index, and nutrient …
