摘要
制备了4种n-3系列高度不饱和脂肪酸(n-3HUFA)含量相等,廿二碳六烯酸(DHA)含量相等,廿碳五烯酸(EPA)含量亦相等,廿碳五烯酸与廿碳四烯酸(AA)的比例分别为5/1,2/1,1/1和0.4/1的实验微粒饲料。探讨了EPA与AA的不同比例对牙鲆仔稚鱼生长、存活、体内相关成分以及对外部压力耐受性的影响。26 d的养殖试验结果表明,当牙鲆仔稚鱼实验微粒饲料中EPA与AA的比例为2/1时,牙鲆仔稚鱼的生长、存活达到最佳。因此,在该试验条件下,牙鲆仔稚鱼实验微粒饲料中EPA与AA的最佳比例为2/1。养殖试验结束后,4组试验稚鱼体内脂肪酸的分析测定结果表明,稚鱼体内AA的含量,随着微粒饲料中AA含量的增高而增大。
A feeding experiment was conducted to investigate the effects of different ratios of EPA/AA in experimental microdiets on the growth, survival, body composition and tolerance to different stresses of Japanese flounder （Paralichthys olivaceus） larvae. Four kinds of experimental microdiets at four ratios of EPA/ AA （5/1, 2/1, 1/1 and 0.4/1）, with the same contents of n-3HUFA, DHA and EPA, were prepared. The results of 26-day feeding experiment indicated that the growth and survival of Japanese flounder larvae were optimal when the ratio of EPA/AA in experimental microdiet was 2/1. After the experiment, we analyzed fatty acids in bodies of larvae. The results showed that the content of AA in bodies of larvae increased with that in microdiets.
