Biochemical Responses of the Bivalve Mollusk Unio tumidus Inhabiting a Small Power Plant Reservoir on the Dniester River Basin, Ukraine.

Hydropower plants (HPPs) can affect the hydrological regime. However, biochemical responses of aquatic animals for the evaluation of this disturbing are not applied yet. The specimens of Unio tumidus were sampled in a reservoir (R) of a small HPP as well as downstream from the dam (DS).
