测定１～２龄卡特拉鱼含肉率，分析同季节不同年龄卡特拉鱼肌肉生化成分表明，随着年龄增长，鱼体肌肉水分含量逐渐减少，而蛋白质和脂肪含量逐渐增加；灰分及无氮浸出物含量变幅很小；氨基酸总含量有一定幅度变化。但它们均无一定规律。同一年龄夏季鱼肌肉水分含量比冬季低，而蛋白质、脂肪、灰分和无氮浸出物含量均比冬季高。同塘饲养的１龄卡特拉鱼和鳙鱼肌肉各生化成分均较为一致。２龄卡特拉鱼肌肉除水分和灰分含量稍低于鳙鱼外，其余各成分含量均稍高于鳙鱼。卡特拉鱼肌肉的水分与蛋白质、水分和脂肪含量的变化呈负相关关系
Determination of 1 to 2 age Cattle carcass meat content, analysis of the same season with different ages of the muscle biochemical composition of Cutler fish showed that with age, the fish muscle moisture content decreased, while the protein and fat content gradually increased; ash and nitrogen Extractable content amplitude is small; total amino acid content has a certain degree of change. But none of them have certain rules. At the same age, the muscle moisture of summer fish was lower than that of winter, while the content of protein, fat, ash and nitrogen-free extract was higher than that of winter. Tong Tong feeding age 1 Catfish and anchovy muscle biochemical composition are more consistent. In addition to the moisture and ash content of the 2-year-old Cutler’s muscle, the contents of other components were slightly higher than those of the anchovy. The water content of cuttlefish muscle was negatively correlated with the change of protein, moisture and fat content
