摘　　要：为了解不同规格瓯江彩鲤的肉质差异和营养特点,采用常规方法,对平均体重53.5、170.8和308.5g的3组稻田养殖瓯江彩鲤进行含肉率、脏体比、营养成分、氨基酸和脂肪酸组成进行了分析比较。结果表明:较大规格(Ⅲ组)的瓯江彩鲤含肉率54.76%,显著高于较小规格的鱼Ⅰ组(40.99%)。3组鱼肌肉中含人体必需氨基酸占总氨基酸的比例均为44%,与非必需氨基酸比值为91%～95%;第一限制性氨基酸均为缬氨酸;Ⅲ组鱼PUFA含量较高,而Ⅰ组鱼EPA和DHA含量较大;4种鲜味氨基酸总量均超过29%。In order to understand the fleshy difference and nutritional composition characteristics of Oujiang colour carp （Cypinus carpio var. color）between different individual sizes, taking 3 groups of colour carp with average body weight of 53.5 g, 170.8 g and 308.5 g respectively as the research object, we analysed and compared their rate of flesh content, ratio of viscera ： body, general nutritional composition and amino acids and fatty acids by conventional methods. The results showed that the rate of flesh content of large-sized fish group 3 （54.76±2.21）was significantly higher than that of small-sized fish group I （40.99±2.83）;in the total content of amino acids in muscle of 3 groups of carp , the essential amino acids （WEAA）were 44% respectively; of which the first limiting amino acid was valine （Val） for all 3 groups. And WEAA/WNEAA （total nonessential amino acids）was 91%-95%. There were more polyunsaturated fatty acids eicosapntemacnioc acid （EPA）and docase hexaeno acid （DHA） in fish amino acids（Asp, Glu, Gly and Ala）were all more than 29%.
