摘要:
鱼粉为水产养殖饲料中主要的蛋白质来源，在鱼粉的产量供不应求以及价格逐年攀升的情况下，就经济上的考量，势必要利用可取代鱼粉的其他蛋白质来源。 故寻找替代鱼粉之蛋白质来源为本次研究重点。 本实验利用添加动物性蛋白质：南极虾粉（K）、乌贼粉（S）和植物性原料：羽扇豆粉（L）、菜籽粕（R）及玉米蛋白（C）取代饲料中的鱼粉，探讨对赤鳍笛鲷成长之影响。
实验共分为三部份：
实验一：赤鳍笛鲷饲料中添加南极虾粉与植物性原料取代鱼粉之最适取代量。
对照组以60%的鱼粉为饲料蛋白质来源，而实验组的饲料使用27%的动物性蛋白质源及45%的植物性原料为饲料蛋白质来源，在实验组中南极虾粉添加量为5~12.5 %，寻求南极虾粉之最适取代量。 饲养结果均显示南极虾粉添加量以10%是最适当的取代量。
实验二：饲料中添加南极虾粉、乌贼粉及植物性原料对赤鳍笛鲷成长之影响。
对照组以60%的鱼粉为饲料蛋白质来源，实验组则使用25%的动物性蛋白质源与45%的植物性原料配制成四组低鱼粉含量的饲料，另增加两组无添加鱼粉的饲料，以20%及17.5%的动物性蛋白质源与50%的植物性原料为饲料蛋白质来源。 经六周的饲养，结果在成长情形上皆以无鱼粉的两组为最差，增重率及饲料效率亦为最低。
实验三：降低饲料中的鱼粉用量对赤鳍笛鲷成长之影响。
对照组以60%的鱼粉为饲料蛋白质来源，实验组饲料中添加的10%南极虾粉及植物性原料，同时将鱼粉用量逐渐降低至17%，经六周的饲养，实验结果各组皆无显著性差异，因此本实验中赤鳍笛鲷饲料中最低鱼粉使用量为17%。

Red striped snapper（Lutjanus erythropterus）with red-colored body, ispreferred cultured fish for Chinese people. It is also the main species of seacage culture in Taiwan. Fish meal is the primary protein and best source infish feeds for aquaculture. The supply of fish meal is unable to meet thedemand and the price is increasing year by year. In this study we look for thereplacement of fish meal. Animal and vegetative ingredients were added toreplace fish meal. The study was divided tree trails.
In the first trail, krill meal and vegetativeingredients were added to replace fish meal in four experimental diets toinvestigate the optimal replacement of krill meal. The results show the optimalreplacement ratio of krill meal is 10%.
In the second trail, krill meal、squid meal and vegetativeingredients were added to replace fish meal in six experimental diets. Sixexperimental diets were divided four low fish meal diets and two non- fish mealdiets. After six weeks of feeding, two groups fed diets without fish meal showbad growth with the lowest weight gain and feed efficiency.
In the third trail, krill meal and vegetativeingredients were added to replace fish meal in diets of red striped snapper andreduce fish meal to 17%. In this trail, the results show 17% of fish meal islimited in diet of red striped snapper .
