Abstract:Thickening of zooplankton by filtering the lake water through nylon netting of mesh-size 10, 20, 30 and 60 μm caused losses amounting to 27, 32, 43 and 54%, respectively, of the real numbers of rotifers. The netting did not significantly change the numbers of crustaceans, and only a small proportion of nauplii (up to 10%) was lost when the 60 μm net was used. Filtering was found to also affect the estimated fertility of rotifers by artificially lowering its value for the ovigerous species - Keratella cochlearis (Gosse), or raising - for the non-ovigerous species, Polyarthra vulgaris Carlin.
