The aim of this paper was to identify the relationship between the degree of macrophyte cover on the lake bottom and the abundance and species richness of larva and juvenile stage assemblages. The analysis of the material verified the hypothesis that as the surface area of macrophyte cover increases so does the abundance, species richness, and diversity of fish aggregations. The investigations were conducted in the heated Lake Licheńskie in 2000-2003 during the period when underwater vegetation is at the height of development (June – September). The spatial differentiation of macrophyte occurrence had a significant impact on the occurrence and differentiation of the fry assemblages. It was confirmed that along with an increase in the macrophyte cover surface area there was also an increase in the species richness and diversity of juvenile fish assemblages. The locations that were most densely overgrown with vegetation had the highest fish biomass and individual weight. In littoral areas without macrophytes, abundant single-species concentrations of fish occurred. The bottom macrophyte cover did not have an impact on the numbers of fish.

The role that invasive Vallisneria spiralis L. plays in determining the species richness of the rotifer community was examined in the littoral zone of two heated (by power stations) lakes near Konin (W. Poland) (Lake Licheńskie – area 153.6 ha, max. depth 13.3 m and Lake Ślesińskie – area 148.1 ha, max. depth 25.7 m). Vallisneria spiralis is a thermophilic and vegetative reproducing species which has been recorded in the lakes since the 1990s. It spreads very quickly in the lakes, forming monospecific, dense beds which, force out all other submerged vegetation. Samples were collected in August 2004 on 8 littoral stations of Lake Licheńskie and Ślesińskie. Five-liter samples of water (plankton species) and macrophytes (epiphytic species) were elaborated separately. An analysis of the taxonomic structure of rotifer communities inhabiting single-species Vallisneria beds and mixed-species (Vallisneria plus other macrophyte species) beds showed that both communities were relatively rich in species and similar in terms of species composition. A total of 100 species of Monogononta were identified. Single-species Vallisneria beds were inhabited by 77 species, whereas 82 species were found at stations with mixed vegetation. Species diversity was relatively high in both types of macrophyte assemblages. Numbers of rotifer species inhabiting the single-species Vallisneria beds are among the average values observed in a littoral zone rich in macrophyte species from lakes of different morphometry and trophic state. The above observations confirm part of the conclusions from literature that invasions by new plant species do not always lead to a decline in the habitat value for native animals. Otherwise, the invaded plant creates the habitat easily colonized by the native plankton and epiphytic invertebrates.
