Ecological subspecies and locally temporal populations of anadromous fish

Resumo

Intraspecific organization and structure of anadromous fish populations (in terms of species of the Oncorhynchus, Salvelinus, and Tribolodon genuses) were investigated. It was shown that the ecological, genetic, and morpho-physiological differences in ecology-temporal (seasonal) races of these fish reached the rank of ecological subspecies. The expediency of more careful and detailed study of intraspecific organization, ecological and locally temporal differentiation of fish, and consideration of the results of these researches was shown in the development of a polymorphic species concept as well as optimization of fish industry—the sustainable organization of fishing, artificial fish breeding, and introduction of fish.
