Cladoceran microfossil remains from the surficial sediments of 19 Danish and 14 Indiana lakes were analyzed quantitatively. An attempt was made to correlate the numbers of remains with C 1 4 primary productivity measurements by previous authors. The Spearman rank correlation method gave no correlation for lakes in different drainage basins. It is suggested that under special circumstances there may be a correlation when only lakes of the same drainage basin are considered.
