 abstract={It was found that the “customary” system of taking plankton samples (every 14 days) caused, in comparison with sampling every 3-S days - a fundamental distortion of the picture of the dynamics and species composition of littoral and euplankton rotifers. The degree of such distortion depends on the frequency and periodicity of the occurrence of particular species.},
