摘要

The grayling (Thymallus thymallus L.) inhabits only a small number of hill-mountain rivers in Serbia. Allthese rivers belong to the Danube river basin. The Republic of Serbia represents a part of the southern zone of this fishspecies’ range of distribution in Europe. The eastern, southwestern and western zones of the grayling’s range ofdistribution have been determined. During the second half of the 20 th century, a decline in the number of its populationshas been observed, primarily because of the construction of hydroenergetic objects, intensified fishing and inadequateprotection. This can result in a shift in the grayling limits of distribution range in South Europe.
