The distribution of lipase (EC 3.1.1.3) in the different parts of the digestive system of Bagarius bagarius, Mastacembelus armatus, Glossogobius giuris and Rohtee cotio has been studied. In the stomach of Mastacembelus, Bagarius and Glossogobius the lipase activity has been found in the mucosa and gastric glands. The intestinal pulb and the intestine of herbivorous Rohtee and in the intestine of the rest of the three fishes show the enzymatic activity in the mucosal epithelium. However, in Mastacembelus and Glossogobius the lipase activity is more pronounced in the intestinal mucosa than that in Bagarius and Rohtee. In the liver, the enzyme is distributed in polyhedral hepatic cells in all the fishes studied specially around the nuclei of the hepatic cells. In the pancreas of Rohtee, the enzyme is distributed in the acinar cells and the cells of islets of Langerhans. The serosa and muscularis of the different portions of digestive system of the four fishes studied are devoid of any lipolytic activity.
对巨魾、纹胸鮡、尖头塘鳢和罗氏野鲮消化系统不同部位的脂肪酶（EC 3.1.1.3）分布进行了研究。在纹胸鮡、巨魾和尖头塘鳢的胃中，已在黏膜和胃腺中发现脂肪酶活性。草食性罗氏野鲮的肠球和肠道以及其余三种鱼的肠道在黏膜上皮中显示出酶活性。然而，在纹胸鮡和尖头塘鳢中，脂肪酶活性在肠道黏膜中比在巨魾和罗氏野鲮中更明显。在肝脏中，该酶分布于所有研究鱼类的多面体细胞中，特别是在肝细胞的细胞核周围。在罗氏野鲮的胰腺中，该酶分布于腺泡细胞和胰岛细胞中。所研究的四种鱼消化系统不同部位的浆膜和肌层没有任何脂解活性。
