EFFECT OF DIETARY PROTEIN LEVELS ON GROWTH PERFORMANCE AND BODY COMPOSITION OF JADE PERCH SCORTUM BARCOO

The effects of dietary protein levels on growth performance and body composition of jade perch were investigated by using white fishmeal as a protein source in pellet feeds.105 jade perch with initial body weight 104.13±0.46g was used in 8-week growth trial.All the test fish were divided into 5 groups with triplicates,which were cultured in 15 concrete tanks at 24±1℃ and fed 5 isoenergic diets containing different protein levels(23.64%,28.45%,33.50%,37.04%,41.62%).The results showed that increase weight rate at 33.50%dietary protein was the highest,which were very significantly (P0.05).
