【摘要】 对我国六个地区（河北沧州、河北黄骅、山东无棣、西藏措勒、内蒙锡林浩特、新疆巴里坤湖）所产卤虫初孵无节幼体的营养组成进行了测定。结果表明，六个产地卤虫初孵无节幼体的蛋白质含量为４６％～５３％，脂肪含量为２１％～２６％，除色氨酸因酸水解未测定之外，六个产地卤虫的无节幼体均含有１７种氨基酸，氨基酸总量为干重的３８％～４４％，必需氨基酸占氨基酸总量的４８％～５０％，六个产地卤虫无节幼体均含有较多的２０：５ｎ－３，１８：３ｎ－３含量很少，为海水型卤虫．其脂肪酸组成因产地而异，其中１８：２ｎ－６和２０：５ｎ－３的含量受产地的影响最大，西藏措勒的２０：５ｎ－３含量最高、达２３．５２％，内蒙锡林浩特最低为７．９０％，六个产地卤虫的无节幼体均缺乏２２：６ｎ－３。更多还原

【Abstract】 The nutritional value of new hatched Artemia nauplii of six geographic strains ( CangZhou, HeBei; HuangHua.HeBei; WuDi, ShanDong; CuoLe, Tibet; XiLinHaoTe, Inner Monglia; BaLiKun Hu,XinJiang) in China was examined. The protein contents of the nauplii were 46% - 53% of dry weight , and the lipid contents were 21% - 26% of dry weight. 17 kinds of amino acids of the nauplii were detected. The content of total amino acids was 38% - 44% . The percentages of the essential amino acid in total amino acid were 48% - 50% . The six strains nauplii contained abundant 20: 5n - 3 and a small amount of 18: 3n - 3. They were marine type. Compositions of the fatty acid were different among Artemia nauplii of the different strains. The contents of 18:2n -6 and 20:5n - 3 were significantly affected by producing area. The contents of 20:5n - 3 from Cuole, Tibet and Xilinhaote, Inner Monglia were 23.52% and 7.90% respectively ,which were the highest and the lowest in the six strains. 22: 6n - 3 was not detected in the strains.更多还原
