Notes
The general patterns in seasonal and spatial distributions of planktic rotifers were investigated in the estuarine shallow waters south of the Darss-Zingst Peninsulae (south coast of the Arkona Sea, Baltic). Keratella cochlearis, Filinia longiseta, and Brachionus quadridentatus form the major part of the summer rotifer biomass peak. Rotifer abundance vary considerably over very small as well as over large distances. The diurnal vertical migration of rotifers is not strong but recognizable. It seems that the rotifers perform shore avoidance reactions. Some possible causes of our observations are discussed and conclusions for optimization of sampling have been drawn.
