Since the fifties, limnologists have been aware of the ability of a fish population to influence its plankton environment through direkt predation. This means not only a reduction in abundance of different species but also a change in the species composition and a change in the size composition within the species. Several field studies have dealt with this problem. Hrbacek and coworkers were able in some small Elbe backwaters to demonstrate the great importance of the fish population size for the species composition in the plankton community (Hrbacek 1958, 1959, 1962, Hrbacek et al. 1961, Hrbacek and Novotna-Dvorakova 1965, Novotna and Korinek 1966). The same problems have been investigated in an illustrative way in the studies concerning the alewife (Alosa pseudoharengus) (Brooks and Dodson 1965). The mechanisms involved in the interspecific relations within the plankton community have also been discussed (Brooks and Dodson 1965, Brooks 1968, Burns and Rigler 1967, Straskraba 1965). The present investigation is a comparison between the plankton fauna (especially the cladocerans) in eight small forest lakes, of which four are treated with rotenone and provided with new fish populations, consisting of new species. Concomitant investigations of physico-chemical limnology were carried out so that factors other than fish predation could be taken into consideration in the evaluation of the results.
