Abstract

The hydrolytic activity of four classes of extracellular enzymes was determined in the surface water in three fish farm ponds. These water basins were inhabited by different developmental stages of carp. The ranking order of the mean enzyme activity rates in the studied water basins was as follows: aminopeptidase > lipase > β-glucosidase > α-glucosidase. The level of activity of the tested enzymes differed among the studied ponds. Each hydrolase had its characteristic horizontal profile of activity. The level of extracellular enzyme activity characterised dynamic influenced by the seasons.
