Commercial stocks of two yellowfin sole populations on the western and eastern shelves of Sakhalin Island are assessed by VPA method using the data on their size-age structure and fishery statistics for 1950-2013. Results of the assessment are compared with the data of bottom trawl surveys conducted in 2000-2013. The yellowfin sole at Sakhalin Island had two periods of high abundance: in the 1950-1960s and in the 1985-1995, but its stocks decreased in the 1970-1980 and after the middle 1990s. This dynamics is similar to the dynamics of other large populations of yellowfin sole in the North Pacific - in the southeastern and western Bering Sea and on the shelf of West Kamchatka. All these changes are caused by natural reasons; fishery has secondary importance and affects on the populations in times of low stock only.
