Four different protein sources were used to formulate isonitrogenous (45% crude protein)、isolipidic (10% crude lipid) and isoenergetic diets in experiment I. Peruvian fish meal (PFM)、Taiwan fish meal (TFM)、poultry meal (PM) and meat and bone meal (MBM) were used as main dietary protein sources. Each diet was randomly assigned to triplicate tanks with 10 fish per tank. Fish were fed three times daily for six weeks. Rock porgy with 10.58g initial body weight fed diet containing TFM had the highest weight gain (314.73%) and was significantly higher than those fed diets containing other protein sources. Specific growth rate (SGR) and survival ranged from 1.84 to 3.39% day-1 and 90 to 100%, respectively. Crude protein and crude lipid of fish muscle ranged from 83.3 to 86.0% and 8.0 to 10.8%, respectively. The crude lipid of liver of rock porgy fed MBM diet (27.1%) was lower than that of fish fed PFM diet (42.1%)、TFM (38.3%) and PM (51.5%).
Six isonitrogenous (crude protein 45%) and isolipidic (crude lipid10%) diets were formulated to replace of 0% (PM0), 20% (PM20), 40% (PM40), 60% (PM60), 80% (PM80) and 100% (PM100) fish meal protein with PM in experiment II. Each diet was randomly assigned to triplicate tanks with 10 rock porgy fish (initial weight 2.05g) per tank. Weight gains of rock porgy fed PM20 (1500.98%) and PM40 (1441.99%) were significantly higher than those of fish fed other treatments. In addition, weight gains of rock porgy fed PM60 (1255.79%) and PM80 (1185.80%) were significantly higher than those of fish fed PM0 (860.31%) and PM100 (742.82%). Fish fed PM0 and PM100 showed no significant differences in weight gain. The SGR of rock porgy fed diets PM20, PM40 and PM60 (6.2-6.6% day-1) showed significantly higher than that of fish fed PM0 and PM100 (5.08-5.37% day-1). Feed conversion ratio (FCR) and survival ranged from 1.70 to 3.53 and 80 to 100%, respectively. Crude protein and crude lipid of fish muscle ranged from 82.3 to 83.2% and 10.8 to 12.5%, respectively. The crude lipid of liver increased with increasing dietary poultry meal.
Five isonitrogenous (crude protein 45%) and isolipidic (crude lipid 9%) diets were formulated to replace of 0% (SPH0), 15% (SPH15), 30% (SPH30), 45% (SPH45) and 60% (SPH60) fish meal protein with SPH in experiment III. Each diet was randomly assigned to triplicate tanks with 10 rock porgy fish per tank. Rock porgy with 2.95g initial body weight fed SPH15 and SPH30 had significantly higher weight gain (585.35% and 618.22%) and SGR (4.58% day-1 and 4.69% day-1) than those fed other treatments. There were no significant differences in weight gain (395.01% and 418.05%) and SGR (3.81% day-1 and 3.92% day-1) between fish fed with SPH0 and SPH60. Survival of rock progy ranged from 97 to 100%. Crude protein and crude lipid of fish muscle ranged from 78.4 to 80.2% and 10.6 to 12.3%, respectively. The crude lipid of liver of rock progy increased with increasing SPH.
