English. In course of the research there was studied a complex of phenotypic signs of trout underyearlings of populations, which were grown in fish-breeding industrial complex for growing of stocking material of salmon id fishes with using of closed water service system on a base of Belarus State Academy of Agriculture (Gorki, Mogilev region, Belarus). As a result of realized research there was provided a description of exterior morphometrical properties of trout underyearlings taken from two populations imported from the Russian Federation and France at the phase of impregnated row. There were discovered the differences between the underyearlings of various origin in terms of absolute and relative properties. There was revealed that two populations of trout fingerlings, formed from material imported from different sources, had differences on a number of morphometric characters, indicating the absence of kinship between them. If the subsequent stages of cultivation will be observed accelerated pace of growth and puberty, a material, which was brought into the Republic of Belarus, can be used as a gene pool for the formation of tribal repairs.
