| 摘 要： | 通过投喂不同藻类饵料,利用GC-MS法,研究饵料对毛蚶浮游幼虫体内脂肪酸组成变化的影响.结果表明,不同饵料对幼虫生长和附着变态速度的影响存在差异,混合饵料组效果最佳;饵料种类和脂肪酸含量对幼虫体内脂肪酸组成和其生长存在显著影响,且体内不饱和脂肪酸含量随着幼虫发育呈下降趋势.在众多脂肪酸中,DHA和EPA对幼虫存活有直接关系,而AA及饱和脂肪酸含量对幼虫生长存在显著影响,ω-3与ω-6脂肪酸含量比值也能反映幼虫生长和变态速度. |

| Abstract: | Effect of algae species on the fatty acid composition of Scapharca subcrenata larva was studied using GC-MS.The result show that the growth and the settlement-metamorphosis rate were influenced by different algae feed;and among diets groups,the mixed-algae group showed better growth performance than the others.The effect of algae species on the fatty acid composition is therefore,significant.Furthermore,its unsaturated fatty acid composition decline as the animal grew.DHA and EPA has direct relationship wit... |
