Experimentally increased fish stock in the pond type lake Warniak. 11, Food resources and availability of the eulittoral zone for fish
Streszczenie w języku polskim
The eulittoral zone is on the average 7% of lake surface and has a high biomass of invertebrate fauna used as food by fish. The availability of this zone decreases in summer due to overgrowing, drying and oxygen deficits. The shore zone area unaccessible in some periods for fish is 11% of the lake surface.
