Pathways of the Amur pink salmon Oncorhynchus gorbuscha to the areas of reproduction
Biannual sequence of high-numerous and low-numerous year-classes of pink salmon ( Oncorhynchus gorbuscha ) is disturbed rarely in the areas close to its spawning grounds where mostly local groupings are landed, as it is shown on the data of fishery statistics in many areas of Russian Far East for 19...
