Abstract.
Features of spatial and vertical distribution, size and age compositions, sex ratio and feeding habits of roughscale sole Clidoderma asperrimum within the outer shelf and upper continental slope (depth range from 100 to 850 m) of the Pacific waters off southeastern Kamchatka and the northern Kuril Islands (47�50' N to 52�N) are considered on the basis of data obtained during 1992-2000.
