Distribution and aspects of population dynamics of the zebra mussel, Dreissena polymorpha (Pallas, 1771), in the lake IJsselmeer area (The Netherlands).

The distribution, settling and growth of the zebra mussel, Dreissena polymorpha Pallas, in Lake IJsselmeer and Lake Markermeer in The Netherlands were studied from 1980 to 1985. In these lakes D. polymorpha is the most important food source for wintering diving ducks. The study was part of an investigation into the carrying capacity of the lakes for these birds.
