Fishes as important indicators of environmental quality in the upper sections of the Tichá Orlice and Divoká Orlice rivers
 Lusk, Stanislav ; Lusková, Věra ; Korunová, Vlasta
Investigations, implemented in the river network of the "Orlice" region over the past twenty years, made it possible to obtain data on the fish communities inhabiting the Tichá Orlice and Divoká Orlice rivers. The rivers are inhabited by salmonid fish communities dominated by Salmo trutta, Thymallus thymallus, Cottus gobio, and Lampetra fluviatilis. Water pollution was gradually limited by building water treatment plants as well as by the significant decrease in the intensity of agricultural activities. The environmental pollution with mercury in the Králíky region, lying on the upper reaches of the Tichá Orlice River, is a specific problem. Nevertheless, the mercury content in fish muscles has exceeded the hygienic limit (0.1 mg.kg-1). Fishermen consuming fish angled in the Tichá Orlice River have shown increased mercury contents in their hair.
