| 摘 要： | 对海水（盐度为28）和淡化（盐度为2）条件下养殖8周的凡纳滨对虾体营养成分蛋白质、脂肪、灰分、矿物质、氨基酸以及脂肪酸组成等进行了比较研究.2种盐度养殖的全虾粗蛋白与粗脂肪含量没有显著差异,但淡化养殖的全虾灰分含量显著降低.从2种盐度养殖的虾壳、肝胰腺、肌肉与血清等组织的矿物元素含量来看,淡化养殖对对虾的组织矿化程度造成一定的影响.淡化养殖的对虾血清蛋白含量下降,而肝胰腺指数却显著上升.2种盐度养殖的对虾肌肉氨基酸总量与脂肪酸总量没有显著差异,但淡化养殖的对虾肌肉必需氨基酸含量上升,而不饱和脂肪酸含量略微下降.结果表明,盐度对对虾各组织成分的影响是对虾对不同盐度的生境进行渗透调节与离子调控的适应性反应. |

| Abstract: | An 8-week feeding experiment was conducted to study the body composition of Litopenaeus vannamei reared in seawater(with salinity of 28) and brackish water(with salinity of 2) respectively,including protein,lipid,ash,amino acid,fatty acid and mineral contents.No significant differences in protein and lipid contents of the whole body were observed among the shrimp reared in the two media,while the whole-body ash content of shrimp reared in brackish water was significantly lower than that in seawater.Judged from the mineral contents of exoskeleton,hepatopancreas,muscle and serum of shrimp reared in such salinity water,low salinity caused a inhibitory effect on the extent of tissue mineralization.The protein content in serum of shrimp reared in brackish water decreased significantly,while the heqatosomatic index increased.There were no significant differences in the total contents of amino acids and fatty acids in the muscle;however,the total content of essential amino acids increased significantly and the total content of unsaturated fatty acids decreased in the muscle of shrimp reared in brackish water.All of these suggested that the effect of salinity on body composition was a reflection of shrimp adaptation to saline media by osmotic and ionic regulation. |
| Keywords: | Litopenaeusvannamei fresh-water culture mineral amino acid fatty acid |
