Title: Genetical adaptation of common kilka Clupeonella cultriventris (Nordmann, 1840) (Actinopterygii
Subtitle: Clupeidae)
Description: For the first time the methods of biochemical genetics studied the genetic diversity and population structure of the kilka in all areas. Obtained new data on the state of the species in the reservoirs of the Upper Volga. Studied physiological and ecological adaptation of the species to the conditions of the Nordic water reservoirs. Set selective importance of a number of genetic loci in relation to the most important abiotic environmental factors. It is established, that in the course of his modern area of the kilka is a genetically unified totality of the populations of Clupeonella cultriventris (Nordmann, 1840). Successful expansion of the species in the cascade of reservoirs of the Volga contributed to the complex set of genetic and biochemical adaptations to live in the fresh waters. It is suggested that the population of anchovy sprat of the Volga water reservoirs were constructed on the basis of freshwater populations in the Saratov backwaters. Significant role in the distribution of genotypes of sprat in the newly established population play a seasonal changes of abiotic and biotic environmental factors.
For ichthyologist, geneticists, ecologists, specialists on the protection and use of natural resources.
