The effectiveness of fish catching using three different methods, in six shallow lakes of Łęczyńsko-Włodawskie Lakeland was compared. The lakes concerned were: Kleszczów, Rotcze, Długie, Sumin, Głębokie Uścimowskie and Syczyńskie and the methods were as follows: electrical fishing, gill net and fyke net. The most fish species and their biggest biomass were reported while using electrofishing.When fishing on the open waters the best effects were obtained using nets of gill net Norden S type, while fyke nets, which were put in littoral, were found to be the least effective method and of greatest selectiveness of species. For fish sampling in shallow lakes, it is best to use several methods, for example, electrofishing in the littoral zone but net fishing on the open waters.
