Abstract
The features of the morphoecological and genetic polymorphism of whitefish ( Coregonus lavaretus L.) from the Keret’ River (White Sea basin) are discussed. According to morphological characteristics this whitefish population is homogeneous. At the same time, the differentiation with the lake whitefish populations of European Russia and Siberia was detected. The differences of the parameters associated with the movement and orientation of individuals in space (body height, length and position of the fins, interorbital distance) were revealed. For the first time the data of the craniological analysis were described for the White Sea whitefish. The results of the mitochondrial ND1 fragment polymorphism analysis confirmed the assumption of the heterogenous origin of the whitefish from the Keret’ River: the descendants of three different phylogenetic lines were found in the population.
