A feeding experiment was conducted to determine the effect of dietary Peruvian fish meal (PFM) protein replaced by Taiwanese fish meal (TFM) protein on the growth performance of orange-spotted grouper Epinephelus coioides. Six isonitrogenous (45.8% crude protein) and isolipidic (11.4% crude lipid) diets were formulated to contain 0, 10, 20, 30, 40 and 50% PFM protein replaced by TFM protein. Proximate composition of crude protein, crude lipid and gross energy ranged from 46.45% to 49.39%, 12.30% to 12.91% and 472.55 to 491.80 kcal/g, respectively. Each diet was randomly assigned to triplicate groups of 12 fish per tank (initial body weight 1.34 g). Fish were maintained in a recirculation seawater system. Water temperature and salinity ranged from 26 to 32℃ and 30 to 33 ppt, respectively. Fish were hand-fed three times daily to apparently satiation for 8 weeks and weighted every two weeks. The termination of the experiment, there were no significant differences in final weight and weight gain percentage of grouper fed diets containing 0, 10, 20 and 30% TFM protein. The weight gain percentages of grouper fed diets containing 40% TFM protein (WG 1300.54%) and 50% TFM protein (WG 1153.69%) were significantly lower than those of grouper fed diets containing 0, 10, 20 and 30% PFM protein. Furthermore, there were no significant differences in survival. The results indicated that the growth performance decreased with increasing TFM. Therefore, based on this experiment, up to 30% of dietary fish meal protein can be replaced by TFM protein without an adverse effect on growth performance of grouper.

本實驗探討以台灣魚粉部份取代飼料中祕魯魚粉蛋白對點帶石斑成長與體組成之影響。以台灣魚粉部份取代祕魯魚粉蛋白0、10、20、30、40和50%並配製成等蛋白與等油脂之六組實驗飼料；飼料粗蛋白、粗油脂及總能量範圍為46.45-49.39%、12.30-12.91%及472.55-491.80 Kcal/100 g。實驗組每缸12隻魚；每組三重複，各處理組魚體初重為1.34克，實驗採用循環水系統，水溫為26-32℃，鹽度為30-33 ppt；每日投餵三餐至飽食，實驗週期為8週。實驗結束後點帶石斑增重率以餵食飼料取代祕魯魚粉蛋白10、20和30% (1870.94-2157.96%)的組別與控制組(2267.71%)沒有顯著差異，而點帶石斑增重率以餵食飼料取代祕魯魚粉蛋白40% (1300.54%)及50%(1153.69%)組別則顯著低於其他各組；各處理組活存率無顯著差異(89%以上)。本實驗結論為台灣魚粉可取代飼料中祕魯魚粉蛋白至30%對點帶石斑的成長並無負面影響。
