Species profiles are literature summaries of the taxonomy, morphology, range, life history, and environmental requirements of coastal species. Dover sole are found in deep waters and prefer silt to muddy-sand bottoms; rock sole occur in shallow waters on soft to firm bottoms. Dover sole mature at about 5 to 7 years and spawn buoyant eggs from November to April; rock sole mature at 3 to 5 years and spawn demersal and adhesive eggs during winter and spring. Dover sole begin benthic life at age 1 and rock sole at 20 mm SL. Dover and rock soles migrate to shallower waters for the summer and to deeper waters for the winter; neither exhibits significant north-south movements. Dover sole live to 46 years and rock sole to 25 years; broken and burned otoliths are used to age both fish. Dover and rock soles feed on benthic infaunal and epifaunal invertebrates. Throughout a wide geographic area both species are affected by skin tumors. These soles are harvested commercially with trawls; northern California and Oregon are the main areas for Dover sole, while the eastern Bering Sea and Aleutian Islands are most important to rock sole. 82 refs., 11 figs., 3 tabs.
