Features of morphology and hydrology for spawning rivers at the northwestern coast of the Okhotsk Sea
At the northwestern coast of the Okhotsk Sea, pink salmon finds its spawning grounds both in big rivers (Uda, Okhota, and some other) and small streams because the size, slopes, and structure of alluvial sediments of the majority of local water bodies are suitable for the spawning. In small streams...
