摘　　要：以改良鲫(Carassius auratus)为试验对象,以罗非鱼料为基础日粮对照,以在基础日粮中添加质量分数1%的螺旋藻为试验处理,进行了100 d的养殖试验.并就螺旋藻对改良鲫的生长性能和鲫鱼肌肉营养成分的影响进行了研究.结果表明,与对照组相比,质量分数1%的螺旋藻处理组鱼平均每天内禀增质量率提高20.15%,鲜味氨基酸和必需氨基酸质量分数、亚麻酸和棕榈酸质量分数、氨基酸各项评分均显著提高.由此认为,饲料中添加质量分数1%的螺旋藻对促进改良鲫生长和改善肌肉营养成分有一定的效果.The control group used tilapia feed for based diet, the test group fed with based diet supple-mented with 1%Spirulina platensis is for 100 days, The growth of Carassius auratus and quality of flesh were determined.The results showed that ingestion of 1%S.platensis increased growth gain rates and the flesh quality.Compared with the control group, the growth gain rates of test group was increased 20.15%, and the total delicious amino acid and essential amino acid, linolenic acid and palmitic acid, amino acid score was also higher than control group.It was concluded that 1%S.platensis could increase fish growth, and be good for its flesh quality.
