The catch per unit effort and the migration of Alaska pollack Theragra chalcogramma were deduced from the catch data of 1, 208 hauls of a stern trawler operated on and around the continental shelf east of the Kamchatka Peninsula and Kurile Islands from October 1974 to December 1975.

Beside those fishes, approximately 131 metric tons of Alaska pollack roe were produced during the voyage from February to April 1975. The mean catch per unit effort in each sub-area of fishing ground was approximately 15.5 metric tons and the peak of the CPUE occured in January and August. The CPUE in the continental shelf east of Kamchatka Peninsula (
