Artificial reproduction and status of stock for pacific salmon

Abstract

Artificial reproduction of pacific salmon in the Russian Far East, as a rule, is carried out with gross violations of scientific recommendations. Perhaps, that’s why positive and negative effects of the salmon farming largely neutralize each other. The following paradox is noted for the Far-Eastern basin: the salmon catches decrease in the areas where fish farming is active but increase in the areas where the salmon reproduction is almost completely provided by natural spawning grounds. Fishery, conservation of natural populations, and artificial reproduction of fish juveniles are still separate and disconnected spheres in Russia, largely due to general state of the national salmon economy.
