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。
By feeding different algal baits, the effects of diet on the fatty acid composition of the larvae were studied by GC-MS. The results showed that the effects of different diets on larvae growth and attachment metamorphosis were different, and the mixed bait group had the best effect. The dietary species and fatty acid content had significant effects on the fatty acid composition and growth of larvae, and the content of unsaturated fatty acids Development showed a downward trend. Among many fatty acids, DHA and EPA are directly related to larval survival, while AA and saturated fatty acids have significant effects on larval growth. The ratio of omega-3 to omega-6 fatty acids also reflects larval growth and metamorphosis.
