Notes

A fish population (carp fry) increases the abundance and the duration of occurrence of plankton rotifers during the four months growing season of the ponds. This is due to the increase in the abundance of detritus and bacterioplankton due to transformation of the pond habitat by fish. Within the Rotifera fauna, the fish population increases the abundance of two small species of Rotifera: Keratella cochlearis (Gosse) and K. quadrata (O.F. Muller). Fish culture in the ponds results in the littoral species of Rotifera disappearing as the result of the elimination of mosaic character of the littoral habitat.
