Description	Here, enzymatic activity of five hydrolases was measured fluorometrically in the fluid collected from traps of four aquatic Utricularia species and in the water in which the plants were cultured. In empty traps, the highest activity was always exhibited by phosphatases (6.1-29.8 mumol l(-1) h(-1)) and beta-glucosidases (1.35-2.95 mumol l(-1) h(-1)), while the activities of alpha-glucosidases, beta-hexosaminidases and aminopeptidases were usually lower by one or two orders of magnitude. Two days after addition of prey (Chydorus sp.), all enzymatic activities in the traps noticeably decreased in Utricularia foliosa and U. australis but markedly increased in Utricularia vulgaris. Phosphatase activity in the empty traps was 2-18 times higher than that in the culture water at the same pH of 4.7, but activities of the other trap enzymes were usually higher in the water. Correlative analyses did not show any clear relationship between these activities.
