Abstract
The effects of subsampling and of the variation within and among sampling stations on the accuracy of the estimates of mean population densities for copepods and cladocerans are examined. For the computation of the coefficient of variation in the mean, the sample variance of log transformed data is appropriate. Accuracy is primarily influenced by variation between sampling stations and to a lesser extent by the variation within a sampling station, while subsampling variation has only a minor effect on the accuracy as long as more than 25 individuals per subsample are counted.
