【摘要】 同批人工育成的香鱼(Plecoglossusaltivelis)苗,分别在溪流拦网放养和人工养殖两种状态下养成,其鱼肉的品质以及所体现的营养价值存在差异。在决定鱼肉营养价值的蛋白质品质和含量方面,通过对氨基酸作AAS、CS、EAAI等一系列的评分比较,发现溪流拦网放养香鱼的蛋白质品质优于人工养殖香鱼,而蛋白质的含量也是溪流拦网放养的香鱼高;脂肪方面,人工养殖香鱼的必需脂肪酸含量较高,因而品质也占优,但是高于溪流拦网放养香鱼的脂肪含量制约了其营养价值的发挥。更多还原

【Abstract】 There are differences in qualities as well as the nutritional values of the meat of Plecoglossus altivelis grown out from the same batch of fingerings propagated artificially,but cultured in stream with blocking net and artificial cultured condition.Based on a series of assessing comparisons of AAS,CS and EAAI on amino acids,the quality of protein of Plecoglossus altivelis stocked in stream with blocking net are better than those of artificially cultured ones.Meanwhile,the protein level in Plecoglossus altivelis stocked in stream with blocking net is also better than that of artificially cultured ones.Because of higher level of the necessary fatty acids,the fat quality of artificially cultured Plecoglossus altivelis is better than that of those stocked in stream with blocking net.However,the fat level of the artificially cultured Plecoglossus altivelis which is much higher than that of those stocked in stream with blocking net limits the play of the nutritional value of the fish.更多还原
