The proportion of the stomach, hepatopancreas, intestine gut and viscera weight to body weigh of Peleobagrus fulvidraco have been calculated, respectively as the digestive tube index. That of the the stomach is 0 01￣0 022, that of the hepatopancreas 0.015￣0.034, that of intestine is 0.011￣0.020, and that of the viscera is 0.031￣0.059. Resulted from these conclution, Pelteobagrus fulvidraco is a carnivorous fish. The pH value of stomach, bile, anterior intestine, middle intestine and posterior intestine is 3.8￣4.6, 4.8￣5.4, 6.5￣7.8, 8.2￣8.5 and 7.6￣7.9, respectively. The mean protease activities of stomach, hepatopancreas, anterior intestine, middle intestine and posterior intestine is 651.7, 643.7, 2916, 5085.6 and 5376.5, respectively. The mean diastase activities of the stomach, heptopancreas, anterior intestine, middle intestine and posterior intestine is 378.6, 439.0, 1697.8, 3672.0 and 3874.9, respectively. However, the Pelteobagrus fulvidraco were reared for 28 days in pond, the activities of the protease and diastase of stomach, hepatopancreas, anterior intestine, middle intestine and posterior intestine is remarkablely increased. These results indicated that the digestive ability is very strong. Pelteobagrus fulvidraco may become a farming fish. The crude protein, crude fat, crude cash, Ca and P of the Pelteobagrus fulvidraco were determined as well as the consist of the amino acid for muscle. It is indicated that the nutritive value of the Pelteobagrus fulvidraco is higher than that of the common carp and grass carp.
