摘　　要：以主成份分析和聚类分析的方法 ,对中国 2 5个不同地理品系卤虫卵的营养成分 (脂类、氨基酸、蛋白质、维生素 )进行了分析和研究。实验结果显示 :(1)通过对不同地理品系卤虫卵的 43个营养因子的主成分分析和聚类分析可把 2 5个不同地理品系卤虫卵分为二个大的类群 :海水型和淡水型卤虫卵。 (2 )C2 0 :5n -3 、C18:3n -3 、蛋白质含量、C16:1、四种营养成分的含量是区别不同地理品系卤虫卵的主要营养特征。(3)生殖方式不影响各品系的营养成分的组成 ,而地理品系间营养成分存在差别。 (4 )淡水型卤虫卵适合于投喂淡水养殖动物 。The nutritional compositions of 25 Artemia cysts of different geographic strains from China were analysed by means of principal components analysis and cluster analysis. The total amount of lipids,amino acids,protein and vitamins were analysed.The experimental results showed:(1)Artemia cysts of 25 strains can be divided 2 groups:A. freshwater type cysts and B. marine type cysts by the methods of principal component analysis and cluster analysis of 43 nutritional factors.(2)C 20:5n-3 , C 18:3n-3 , proteins, C 16:1 were primary nutritional components among Artemia cysts of different geographic strains. (3)Reproductive type can not affect the nutritional composition, but there were difference among Artemia cysts of different geographic strains.(4)The freshwater type Artemia cysts only suitable for feeding to freshwater animals and marine type Artemia cysts containing C 20:5n-3 suitable for feeding to marine animals.
