The aim of this study is to examine in vitro the effect of herbicide Roundup in a wide range of concentrations (from ultralow to high) on the level of glycosidase activity in juvenile fish. Enzyme activity was determined in the whole body of common carp Carassius carassius (L.) and in the intestine of roach Rutilus rutilus (L.), caught in the coastal part of the Rybinsk reservoir (Yaroslavl region). The amylolytic activity, reflecting the total activity of enzymes that hydrolyze starch (a-amylase, glucoamylase and maltase) was determined by the modified Nelson’s method. Maltase activity was determined by glucoseoxidase method with the help of the set for Clinical Biochemistry "Fotoglyukoza". The concentration range of Roundup (as glyphosate) was 1·10-13 μg/l to 1 g/l. It was found that the amylolytic activity in the whole body of carp was higher compared to the control at ultralow concentrations of Roundup (1·10-13-1·10-8 μg/l), and generally lower than in the control at higher concentrations. The amylolytic activity in the roach intestine was lower than that in the control in the range of all studied Roundup concentrations. The maltase activity in the intestine of roach was higher compared to the control only at herbicide concentrations of 0.01 mg/l to 1 g/l, no significant effect was observed at the lower concentrations. At the same time the concentrations of the herbicide, which differ by 2-17 orders of magnitude, can cause equal effect.
