Although it was overfished in the 1960s stocks have recovered, and the biomass of rock sole in the Bering Sea and Aleutian Islands population is now estimated to be very high, at twice the level required to support maximum sustainable yield. In 2008 the estimated rock sole biomass in the Gulf of Alaska fishery was some 161,617 tons, compared to catches ranging from 1,468 tons in 2004 to 4,260 tons in 2007. Alaska accounts for the majority of the worldwide harvest of this fish, catching over 52,000 tons of rock sole in 2008.
Rock sole fishing off the coast of the United States is managed by the Pacific Fishery Management Council and the North Pacific Fishery Management Council, two of eight U.S. Regional Fishery Management Councils.
