Evaluating soybean protein concentrate hydrolysate as a fishmeal substitute in the diet for mandarin fish (<i>Siniperca chuatsi</i>): Based on growth, intestinal health, flesh quality and nutrient metabolism.

ABSTRACT: The present experiment investigated the effects of soybean protein concentrated hydrolysate (SPCH) replacing fishmeal (FM) on the growth performance, intestinal health, flesh quality, and nutrient metabolism of mandarin fish (Siniperca chuatsi). Five isonitrogenous and isolipidic diets were designed with different levels of dietary fishmeal substituted with SPCH at 0 (FM55), 18.70% (FM45), 37.16% (FM35), 55.40% (FM25), and 73.41% (FM15), respectively. Each diet was fed to three replicate groups of mandarin fish (a total of 450 fish, 37.18 ± 0.01 g) twice daily for 8 consecutive weeks, with 30 individuals per tank. The results showed that when the replacement level of SPCH did not exceed 37.16%, no significant effects on the growth of mandarin fish were observed (P > 0.05). Hi
