SINOPSIS

The article deals with food spectra and trophic relations between the brown trout (Salmo trutta morpha fario L.) and European grayling (Thymallus thymallus L.) in rivers of the Transcarpathian region. Strained trophic relationships between studied fishes are possible due to significant overlap of the feeding spectra over summer and autumn because of low biomass of zoobenthos in the studied rivers.

PALABRAS CLAVE: the brown trout, the European grayling, feeding, trophic relations, zoobenthos, mountainous rivers, Transcarpathia.
