对长江上游铜鱼和圆口铜鱼的肝胰腺进行了比较研究 .两种铜鱼的肝胰腺都很发达 ,且同属于含脂肪为主的类型 ,二者在结构和成分上虽有一定程度的相似 ,但差异也十分明显 :铜鱼的肝胰腺分为 3叶 ,肝胰腺结构较为致密 ,肝细胞较小 ,肝糖元含量较多 ,肝胰指数为 2 .2 % ,蛋白质含量 8.7% ,脂肪含量 18.2 % ;圆口铜鱼的肝胰腺分为 2叶 ,肝胰腺结构较为疏松 ,肝细胞较大 ,肝糖元含量很少 ,肝胰指数为 3.8% ,蛋白质含量 8.8% ,脂肪含量 2 2 % .
Hepatopancreas were comparatively studied between the copper fish and the round-necked copper fish in the upper reaches of the Yangtze River.The hepatopancreas of both copper-fish species are well-developed and both belong to the fat-containing type, both of which have a certain degree of structure and composition , But the difference is also obvious: the hepatopancreas of the copper fish is divided into three leaves, the structure of the hepatopancreas is compact, the hepatocytes are smaller, the liver glycogen content is more, the hepatopancreas index is 2.2% and the protein content is 8.7% , Fat content 18.2%; round-necked copperfish hepatopancreas is divided into two leaves, the structure of the liver and pancreas is relatively loose, large hepatocytes, hepatic glycogen content is very small, liver and pancreatic index 3.8%, protein content 8.8%, fat content twenty two % .
