Dreissena polymorpha (Pallas, 1771) [WoRMS]
|
| Abstract |
In 1977–81 the river Rhine near the lake of Constance held the highest densities of Zebra Mussels (Dreissena polymorpha) ever found in Central and Western Europe with up to 12 kg/m2 fresh biomass. Wintering diving ducks and Coots consumed every year 97% of the standing crop. The population maintained itself by mass immigration of mainly 1-year-old mussels during the summer. This leads to large temporal and spatial (within 4 km) fluctuations of biomass. |
