Investigation of histology structure and some histochemical characteristics of stomach-intestine tract in the spiny eel, (Mastacembelus mastacembelus Bank and Solander, 1794). In this study, the histological structure and histochemical characteristics of stomach-intestine tract five spiny eel (Mastacembelus mastacembelus Bank ve Solenderi 1794), obtained in Keban Dam Lake were examined in the light microscope. The stomach of M.mastacembelus are consist of three region called cardiac, fundus and pyloric. In the all the region of stomach found tunica mocosa, submucosa, tunica muscularis and tunica serosa. The stomach mucosa of M.mastacembelus had folded and columnar cells, found gastric gland in the cardiac and fundus stomach, no observed in the pyloric stomach. In all the region of stomach showed circulary and longitudinally muscularis layer and tunica serosa. As a result of histochemically staining of stomach were determined that in the mucous cell included different gradually neutral glycocongugate and acidic glycocongugate. The intestine of M.mastacembelus studied as assending, intermedia and dessending. It was found out that the intestine tract wall of M.mastacembelus consisted of four layers called mucosa, submucosa, muscularis and serosa, mucosa of intestine compose of prismatic epithelial cells and numerous goblet cells. Tunica muscularis occured longitudinally and circular muscle fibril. Tunica serosa formed the connective tissue. As a result of histochemically staining in the goblet cell of intestine were determined that the goblet cell included strong acidic glycocongugate.
