摘　　要：根据不同季节框鳞镜鲤的形体参数、背部和腹部肌肉的营养成分,采用因子分析和系统聚类对框的鳞镜鲤进行特征分类研究。结果表明:框鳞镜鲤在春、夏季的主要形体特征是体形较大,内脏比例较高,鱼皮比例较低;而秋、冬季的特征主要是体形较小,鱼鳞、内脏比例较低而肌肉比例较高。腹部肌肉在春、夏季的主要特征是蛋白质、游离氨基酸、灰分含量较低,而水分含较高;秋季的主要特征是蛋白质和灰分含量较高,水分含量较低;冬季的主要特征是蛋白质、粗脂肪、总糖含量较高,水分较低。背部肌肉在春季的特征是蛋白质、粗脂肪、总糖和灰分含量较低,游离氨基酸和水分含量较高;在夏季的主要特征是粗脂肪和总糖含量较高,游离氨基酸、灰分、水分较低;而在秋、冬两季的特征主要是粗脂肪、总糖和水分含量较低,蛋白质、游离氨基酸及灰分含量较高。Factor analysis and system clustering were used to study the classification of mirror carps in different seasons based on body parameters and nutritional composition in their back and abdominal muscles.The results showed that the major body characteristics of mirror carps in spring and summer exhibited larger bodies,higher proportion of viscera and lower proportion of skin;in contrast,mirror carps in autumn and winter had smaller bodies,lower proportion of scale and viscera,and higher proportion of fish muscle.The major nutritional characteristics of abdominal muscle from mirror carps in spring and summer revealed lower contents of proteins,free amino acids and ash,and higher content of water;the major nutritional characteristics of abdominal muscle from mirror carps in autumn had higher contents of proteins and ash,and lower content of water;the major nutritional characteristics of abdominal muscle from mirror carps in winter had higher contents of proteins,crude fat and total sugar,and lower content of water.The major nutritional characteristics of back muscle from mirror carps in spring revealed the lower contents of proteins,crude fat,total sugar and ash,and higher contents of free amino acids and water;the major nutritional characteristics of back muscle from mirror carps in summer had lower contents of crude fat and total sugar,and lower contents of free amino acids,ash and water;the major nutritional characteristics of back muscle from mirror carps in autumn and winter had lower contents of crude fat,total sugar and water,and higher contents of proteins,free amino acids and ash.
