Veliger larvae of Dreissena (Bivalvia, Dreissenidae) in the zooplankton of Lake Pleshcheyevo (Yaroslavl Region, Russia)

The abundance dynamics, spatial distribution and role of freshwater zebra mussel veligers in the structure of zooplankton were analyzed based on observations in 2012–2016 in Lake Pleshcheyevo (Yaroslavl Region). The mean abundance of larvae in the pelagial of the lake in the peak period (summer) ran...
