The study aims to assess the use of marine protein hydrolysates as fish meal substitutes in diets for Asian seabass.
Conducted an eight-week feeding trial with different dietary treatments
Compared high-fish-meal diet with low-fish-meal diets supplemented with tuna hydrolysate, shrimp hydrolysate, and salmon silage
Analyzed growth performance, feed utilization, and health status parameters
LFM + TH diet significantly improved weight gain, specific growth rate, and feed conversion ratio
Histological analysis showed increased villus length and goblet cell count, indicating enhanced nutrient absorption
No significant differences in hematological and immunological parameters were found
