2、一次。结果表明:强化组各时段的二十二碳六烯酸、棕3鄄系列多不饱和-1脂肪酸总量以及多不饱和脂肪酸总量均显著高于对照组;除了75和225mg·L组6h的二十碳五烯酸与对照组无显著差异外,其他各时段的二十碳五烯酸亦显著高于对照组;75-1-1-1mg·L组18h以及150mg·L组12和18h的二十碳四烯酸亦显著升高;150mg·L组-1的必需氨基酸总量和总氨基酸含量均显著高于对照组,此外,150mg·L组各时间段的必-1需氨基酸总量/氨基酸总量比值显著高于其他两个强化组和对照组,225mg·L组12h的必需氨基酸总量/氨基酸总量比值显著高于对照组
3、;南极大磷虾粉对卤虫的脂肪酸和氨基-1酸均具有较好的营养强化效果,并以150mg·L的强化浓度,12和18h的强化时间为宜。关键词摇南极大磷虾粉;卤虫;脂肪酸;氨基酸中图分类号摇S963.16摇文献标识码摇A摇文章编号摇1000-4890(2013)6-1563-08NutrientenrichmenteffectofAntarctickrill(Euphausiasuperba)powderonthefattyacidandaminoacidcompositionsinArtemianauplii.LUJian鄄xue,LINTing鄄tin
