Abstract
Water samples from Mirror Lake, New Hampshire, were concentrated with a transparent filtering funnel fitted with different‐sized mesh screening. The commonly used No. 20 (75‐ µ mesh) plankton netting gave significantly low numbers of individuals and biased egg ratios for natural populations of planktonic rotifers in the lake.
