Abstract
Pink salmon is a traditional object of fishing in Sakhalin coastal waters of the Tatar strait, where it was caught for a long time off the southern part of the coast. In the last 20 years, there has been a shift in timing of pink salmon approach to the area of trap-nets a later date, as well as the main fishing sites shifting from the southern to the central areas of the coast. During these years, water cooling has observed in May, which could cause a delay in fish migration to the Tatar Strait. Also, in June and July in the northern regions, due to rapid warming, the water temperature became the same as in the southern regions of the strait. It’s known that such thermal regime changes largely determined by the intensity of penetration of the Tsushima current waters into the Tatar Strait, which apparently caused the shift of pink salmon accumulations in the strait to the north.
