摘    要:报道吉林朝阳水库的鲢,鳙,镜鲤及丰鲤的肌肉总脂有脂肪酸组成在越冬期间的变化,其基本分布不受饥饿的影响,但可观察到饱和脂肪酸略有减少;饱和脂肪酸与不饱和脂肪酸的比呈现规律性下降,这是对长期低温环境的反应。

关 键 词:    镜鲤  杂交鲤  越冬  脂肪酸

Abstract:This paper reports the changes of fatty acid composition of silver carp,bighead carp,mirror carp and hybrid carp cultured in cages in Chao Yang reservoir of Jilin Province during winter.The fatty acids composition of total lipids of muscle in four kinds of fishes was not affected owing to starvation. But the content of saturated fatty acids and the ratio of saturated to unsaturated fatty acids reduced in low temperature. The monoethylenic acids increased and docosahexenoic acid (DHA)decreased significantly in hybrid carp. The changes may affect over-winter capability of carp.
Keywords:Hypophthalmichthys molitrix  Aristichthys nobilis  Cyprimus carpio  Hybrid carp  Over-winter  Fatty acid
