摘要:
魚粉為水產(chǎn)養(yǎng)殖飼料中主要的蛋白質(zhì)來源，在魚粉的產(chǎn)量供不應(yīng)求以及價(jià)格逐年攀升的情況下，就經(jīng)濟(jì)上的考量，勢必要利用可取代魚粉的其他蛋白質(zhì)來源。 故尋找替代魚粉之蛋白質(zhì)來源為本次研究重點(diǎn)。 本實(shí)驗(yàn)利用添加動物性蛋白質(zhì)：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(shí)驗(yàn)共分為三部份：
實(shí)驗(yàn)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(zhì)來源，而實(shí)驗(yàn)組的飼料使用27%的動物性蛋白質(zhì)源及45%的植物性原料為飼料蛋白質(zhì)來源，在實(shí)驗(yàn)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(yǎng)結(jié)果均顯示南極蝦粉添加量以10%是最適當(dāng)?shù)娜〈�量�?
實(shí)驗(yàn)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(zhì)來源，實(shí)驗(yàn)組則使用25%的動物性蛋白質(zhì)源與45%的植物性原料配制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(zhì)源與50%的植物性原料為飼料蛋白質(zhì)來源。 經(jīng)六周的飼養(yǎng)，結(jié)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(shí)驗(yàn)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(zhì)來源，實(shí)驗(yàn)組飼料中添加的10%南極蝦粉及植物性原料，同時(shí)將魚粉用量逐漸降低至17%，經(jīng)六周的飼養(yǎng)，實(shí)驗(yàn)結(jié)果各組皆無顯著性差異，因此本實(shí)驗(yàn)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, 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 .
