摘要:	海鱺：擁有許多特點(diǎn)讓海鱺成為一個(gè)理想的集約養(yǎng)殖品種，全世界目前在中國(guó)、臺(tái)灣、越南…等地，有日益升高的養(yǎng)殖趨勢(shì)。魚粉為水產(chǎn)飼料原料的一種，具有許多優(yōu)點(diǎn)而成為魚飼料主要的蛋白質(zhì)來源，對(duì)于魚類成長(zhǎng)非常重要。由于魚粉產(chǎn)量無法增產(chǎn)、需求量增加，以致價(jià)格逐年攀升，故尋找方法來降低魚飼料中魚粉之比例為目前研究之趨勢(shì)。先前的實(shí)驗(yàn)顯示羽扇豆粉（Lupin meal）、菜籽粕（Rapeseed meal）及玉米蛋白（Corn protein）各自分別取代魚粉在海鱺飼料中的最適量為20％、10％、15％，取代后海鱺成長(zhǎng)均與對(duì)照組無差異，在兩種原料搭配下，海鱺的成長(zhǎng)依然有對(duì)照組的74％，然而在三個(gè)植物性原料一起搭配下，實(shí)驗(yàn)組的成長(zhǎng)只可達(dá)到對(duì)照組的63％。為了尋求更低魚粉的配方，本實(shí)驗(yàn)利用南極蝦粉（Krill meal）、羽扇豆粉（Lupin meal）、菜籽粕（Rapeseed meal）及玉米蛋白（Corn protein）取代飼料中之魚粉探討對(duì)海鱺成長(zhǎng)之影響。實(shí)驗(yàn)一：對(duì)照組以60 %魚粉為飼料蛋白質(zhì)來源，實(shí)驗(yàn)組則添加南極粉及植物性原料，分為K125、K100、K075、K050四組，南極蝦粉含量為12.5％、10％、7.5％、5％，魚粉含量由60%降至14.5%，測(cè)試其對(duì)于海鱺之成長(zhǎng)效果。經(jīng)42天飼養(yǎng)，海鱺成長(zhǎng)顯示實(shí)驗(yàn)組K100與K075的增重表現(xiàn)最佳，表示在低魚粉配方的飼料中，添加7.5%-10％的南極蝦粉為最適量。實(shí)驗(yàn)二：對(duì)照組60 %魚粉為飼料蛋白質(zhì)來源，實(shí)驗(yàn)組則添加南極蝦粉及植物性原料，變動(dòng)配方中菜籽粕與魚粉之多寡，分為FM60、F25R2、F20R5與F17R10。經(jīng)42天飼養(yǎng)，實(shí)驗(yàn)組中F25R2組在增重率及飼料效率最佳，F17R10最差。 Cobia, Rachycentron canadum, posses many features that make this species has ideal candidate for intensive aquaculture. Successful commercial production of cobia in China, Taiwan, Vietnam...et al., have very height interest for the culture of this species on global basis. Fish meal have many advantages, especially be demanded in aquaculture growth performance, let make fish meal to become a major protein source in aquaculture feeds. Due to steady yield and short of demand, the price raises recently years. The research direction is tendency towards reducing the percentage of fish meal in aquaculture feeds. Previous study show lupin meal, rapeseed meal, corn protein, respective formulating in 20%, 10% and 15% of cobia feeds, can decrease usage of fish meal and had no difference in growth performance. In the combination formula of two vegetative ingredients, cobia still had 73% growth performance of control diets. However in the combination formula of three vegetative ingredients, has only 63% growth performance of control diets. For seeking lower fish meal formula, this study was focus the growth performance of cobia in using krill meal combine with lupin meal, rapeseed meal and corn protein for reducing the ratio of fish meal in cobia feed. Experiment I : Using 60% fish meal formula as main protein source as control diet, experiment diets named K125, K100, K075, K050 because them contain krill meal 12.5%, 10%, 7.5%, 5% respectively. Experiment diets reduce fish meal from 60% to 14.5% to test their growth performance of cobia. After 42 days feeding, K100 and K075 have best weight gain ratio, means low-fish meal formula diet which contain 7.5%-10% krill meal are optimum. Experiment II : Using 60% fish meal formula as main protein source as control diet, all experiment diets contain 10% krill meal and arrange percentage of rapeseed meal and fish meal, each named F25R2, F20R5 and F17R10. After 42 days feeding, F25R2 had best weight gain and feed efficiency, but F17R10 had worst growth performance.
