Abstract
The route survey in the lower part of the Utesny creek (Paramushir Island) was conducted to explore the state of spawning grounds for pink salmon Oncorhynchus gorbuscha and to examine their filling by spawners. The spawners were subjected to biological analysis with measuring their morphometric and physiological parameters. Besides, the data on granulometric composition of soils on the spawning grounds were updated.
