Main characteristics of the Lake Pleshcheyevo population of Dreissena polymorpha (Bivalvia, Dreissenidae)

Abstract

The main characteristics of the population of Dreissena polymor­pha (Pallas, 1771) in Lake Pleshcheyevo in 2014–2016 are dis- cussed, and two different sampling methods for D. polymorpha are compared. The lack of mass reproduction of D. polymorpha in 2015 is possibly related, among other causes, to climate change and alterations in the temperature regime of the lake. Dreissena is shown to be one of the main benthic suspension feeders in Lake Pleshcheyevo.
