Abstract
Salinity is one of the leading environmental factors influencing the distribution of zebra mussel Dreissena polymorpha in natural conditions. The data on the tolerance range of salinity that were obtained by predecessors under field conditions and during experimental studies differ significantly. This makes it difficult to assess the possible range of distribution of zebra mussel under natural conditions and predict the possibility of its introduction to new water bodies. Using the indices of osmotic and ionic homeostasis as a research method, we have tried to estimate the tolerance range and optimal, critically low, and critically high salinity zones for D. polymorpha. The results can be used to predict the range of distribution of zebra mussel in nature and assess the physiological state of the mollusks in natural and laboratory conditions.
