摘要
研究了泥鳅消化道指数及消化酶活性在肠道不同部位(前肠、中肠及后肠)和肝胰脏的分布。试验结果表明,泥鳅比肠长为0.335±0.006,比肠质量为0.021±0.002,比肝质量为0.015±0.001,其特征偏肉食性。泥鳅肝胰脏淀粉酶、蛋白酶和脂肪酶的活性均极显著高于其他部位,分别为(45.464±2.442)(、580.515±12.282)、(28.889±3.849)U/ml。
Digestive tract index and distribution of digestive enzyme in foregut, midgut, hindgut and hepatopancreas of oriental weatherfish (Misgurnus anguillicaudatus)were studied. It was found that the fish had length (IL)/total length (TL) of 0. 335±0.006, intestinal weight (IW)/body weight (BW) of 0. 021 ±0. 002 and hepatopancreas weight (HW)/BW of 0. 015±0. 001, similar to many other predatory fish. There were more activities of amylase (45. 464±2. 442) U/ml, protease (580. 515±12. 282) U/ml and lipase (28. 889±3.849) U/ml in the hepatopancreas than those in the intestine.
