Artificial reproduction of pacific salmons in the Amur River basin: history, current state, prospects
Experience of pacific salmon artificial reproduction is discussed. Generalized data on juveniles (mostly fall chum salmon) release from hatcheries in the Amur River basin are presented. Information about the fish eggs origin (collection points) and transportation to incubation is provided. Some loca...
