Abstract

The fundamental reasons for the decline in the number of natural salmon herds in the countries of the northern Pacific basin and in the southern waters of the Russian Far East are given. It is shown how the scientifically unjustified creation of a system of salmon hatcheries caused the formation of negative ecosystem, social and economic consequences from large-scale artificial cultivation of all types of Pacific salmon. The colossal influence of ecological and epigenetic influence on the transformation of ontogenesis, reduction of vitality and reproduction of healthy offspring, loss of navigation-innate instinct (homing) in artificially raised Pacific salmon of the genus Oncorhynchus is considered.
