Vertical distributions at noon and midnight of copepodites, males and females of three coexisting species of freshwater cyclopoid copepods, Cyclops vicinus (a cold-water form), Thermocyclops crassus and Mesocyclops leuckarti (warm-water forms), were studied in Dreiangel Lake, a small eutrophic gravel pit. The largest species, C. vicinus , inhabits deep water layers, both at noon and midnight, while the smaller species, T.crassus and M.leuckarti , inhabit upper water layers. In all three species, copepodites and males live closer to the water surface than females. In summer, abundance of the smallest species ( T.crassus ) is highest, although finite birth rates are lowest. The distribution patterns and population characteristics suggest that the vertical distribution of cyclopoid copepods in Oreiangel Lake is mainly governed by fish predation; different temperature tolerances and preferences of the three species may also be of significance.
