Abstract
魚粉為水產養殖飼料中主要的蛋白質來源，在魚粉的產量供不應求以及價格逐年攀升的情況下，就經濟上的考量，勢必要利用可取代魚粉的其他蛋白質來源。故尋找替代魚粉之蛋白質來源為本次研究重點。本實驗利用添加動物性蛋白質：南極蝦粉（K）、烏賊粉（S）和植物性原料：羽扇豆粉（L）、菜籽粕（R）及玉米蛋白（C）取代飼料中的魚粉，探討對赤鰭笛鯛成長之影響。
實驗共分為三部份：
實驗一：赤鰭笛鯛飼料中添加南極蝦粉與植物性原料取代魚粉之最適取代量。
對照組以60%的魚粉為飼料蛋白質來源，而實驗組的飼料使用27%的動物性蛋白質源及45%的植物性原料為飼料蛋白質來源，在實驗組中南極蝦粉添加量為5~12.5 %，尋求南極蝦粉之最適取代量。飼養結果均顯示南極蝦粉添加量以10%是最適當的取代量。
實驗二：飼料中添加南極蝦粉、烏賊粉及植物性原料對赤鰭笛鯛成長之影響。
對照組以60%的魚粉為飼料蛋白質來源，實驗組則使用25%的動物性蛋白質源與45%的植物性原料配製成四組低魚粉含量的飼料，另增加兩組無添加魚粉的飼料，以20%及17.5%的動物性蛋白質源與50%的植物性原料為飼料蛋白質來源。經六週的飼養，結果在成長情形上皆以無魚粉的兩組為最差，增重率及飼料效率亦為最低。
實驗三：降低飼料中的魚粉用量對赤鰭笛鯛成長之影響。
對照組以60%的魚粉為飼料蛋白質來源，實驗組飼料中添加的10%南極蝦粉及植物性原料，同時將魚粉用量逐漸降低至17%，經六週的飼養，實驗結果各組皆無顯著性差異，因此本實驗中赤鰭笛鯛飼料中最低魚粉使用量為17%。
Red striped snapper（Lutjanus erythropterus）with red-colored body, is preferred cultured fish for Chinese people. It is also the main species of sea cage culture in Taiwan. Fish meal is the primary protein and best source in fish feeds for aquaculture. The supply of fish meal is unable to meet the demand and the price is increasing year by year. In this study we look for the replacement of fish meal. Animal and vegetative ingredients were added to replace fish meal. The study was divided tree trails.
In the first trail, krill meal and vegetative ingredients were added to replace fish meal in four experimental diets to investigate the optimal replacement of krill meal. The results show the optimal replacement ratio of krill meal is 10%.
In the second trail, krill meal、squid meal and vegetative ingredients were added to replace fish meal in six experimental diets. Six experimental diets were divided four low fish meal diets and two non- fish meal diets. After six weeks of feeding, two groups fed diets without fish meal show bad growth with the lowest weight gain and feed efficiency.
In the third trail, krill meal and vegetative ingredients were added to replace fish meal in diets of red striped snapper and reduce fish meal to 17%. In this trail, the results show 17% of fish meal is limited in diet of red striped snapper.
