Abstract: It is studied the effects of temperature on the protease,amylase and lipase activities in digestive tissues of Hemibarbus labeo. The results show that in the setting temperature ranges, the activities of protease,amylase and lipase show the trend of increasing first and then decreasing. The optimum temperature for the protease and amylase activities in the hepatopancreas, forgut, midgut of Hemibarbus labeo were 40 ℃. The optimum temperature for the protease and amylase activities in the hindgut of Hemibarbus labeo were 35 ℃. The optimum temperature for the lipase activities in the hepatopancreas, forgut and midgut were 45 ℃, while in the hindgut, the optimum temperature for the activity of lipase was 40 ℃.

Key words: Hemibarbus labeo, temperature, digestive enzymes
