Effect of diets containing different types of sardine waste (Sardinella sp.) protein hydrolysate on the performance and intestinal morphometry of silver catfish juveniles (Rhamdia quelen)

In this study two fractions of muscle hydrolysate were tested, soluble and insoluble (FSM and FIM), they were assessed individually and combined with each other (FSM+FIM). Also, two fractions of hydrolyzed viscera: soluble of natural and industrialized viscera (FSVN and FSVI) were tested on the perf...
