选取野生黄鳝的稚鳝 1 2尾 (体重 2 2 .2 5～ 2 5 .95 g)、幼鳝 9尾 (体重 64.65～ 78.89g)、成鳝 6尾 (体重 2 0 7.1 6～2 2 4.1 6g) ,对不同生长阶段的黄鳝分别随机分为 3个重复 ,在实验室内饥饿 2 4h,解剖并取出黄鳝的胃、肠和肝脏分别称重 ,并测量肠的长度 ,然后分别取一定量胃、肠和肝脏匀浆 ,制取上清液测定酶活力。结果显示 :不同生长阶段黄鳝的胃重 /体重基本一致 ,黄鳝的肠长 /体长指数从稚鳝到成鳝有下降的趋势 ,不同生长阶段的肝脏指数相互之间差异显著 (p<0 .0 5 ) ,稚鳝与成鳝肝脏指数相差极显著 (p<0 .0 1 ) ;幼鳝胃蛋白酶活力高于其他阶段 ,但差异不显著 (p>0 .0 5 ) ,稚鳝与幼鳝的肠蛋白酶活力基本一致 ,但与成鳝相比差异显著 (p<0 .0 5 ) ,肝脏蛋白酶活力随黄鳝的长大而增加 ,但相互之间差异不显著 (p>0 .0 5 ) ;稚鳝、幼鳝、成鳝的肠道淀粉酶活力相互之间差异显著 (p<0 .0 5 ) ,其中稚鳝和成鳝差异极显著 (p<0 .0 1 ) ;稚鳝和幼鳝的肠脂肪酶与成鳝相比差异显著 (p<0 .0 5 ) ,但稚鳝与幼鳝之间差异不显著 (p>0 .0 5 ) ;稚鳝的肝脏淀粉酶活力与幼鳝、成鳝相比差异显著 (p<0 .0 5 ) ,但幼鳝与成鳝之间的肝脏淀粉酶活力差异不显著 (p>0 .0 5 ) ,3个不同阶段黄鳝的肝脏脂肪酶活力差异也不?
12 wild juvenile eel (body weight 22.5-2.595g) were selected, and 9 juvenile eel (body weight 64.65-78.89g) and 6 eel (body weight 20.76-2.24.1 6g). The eels of different growth stages were randomly divided into three replicates, starved for 24 hours in the laboratory, and the stomach, intestine and liver of the eel were dissected and weighed separately, and the length of the intestine was measured. Then, Stomach, intestine and liver homogenate, the system was prepared supernatant enzyme activity. The results showed that the gastric weight / body weight of the eel at different growth stages were basically the same. The intestinal length / body length index of the eel decreased from the young eel to the adult eel, and the liver indexes in different growth stages were significantly different from each other (p <0. (P <0.01). The pepsin activity in juvenile eel was higher than that in other stages, but the difference was not significant (p> 0.05). The juvenile eel and juvenile liver index were significantly different Eel intestinal enzyme activity is basically the same, but compared with the adult eel was significantly different (p <0.05), liver protease activity increased with the growth of rice eel, but the difference was not significant (p> 0.05 ). The intestinal amylase activities of juvenile eel, juvenile eel and adult eel were significantly different from each other (p <0.05), of which the difference between juvenile eel and adult eel was significant (p <0.01) (P <0.05), but there was no significant difference between juvenile eel and juvenile eel (p> 0.05). The hepatic amylase activity of juvenile eel Compared with the young eel and the adult eel, the difference was significant (p <0.05), but there was no significant difference in the liver amylase activity between the young eel and the adult eel (p> 0.05) Liver lipase activity difference also ?
