Pacific rockfish + Alaska pollock

Sebastes is a genus of fish in the family Sebastidae (though some include this in Scorpaenidae), most of which have the common name of rockfish. A few are called ocean perch, sea perch or redfish instead. Most of the Sebastes species live in the north Pacific, although two (S. capensis and S. oculatus) live in the south Pacific/Atlantic and four (S. fasciatus, S. mentella, S. norvegicus and S. viviparus) live in the north Atlantic. The coast off South California is the area of highest rockfish diversity, with 56 species living in the Southern California Bight.

Alaska pollock or walleye pollock (Theragra chalcogramma) is a species of the cod family Gadidae. Alaska pollock is a semipelagic schooling fish widely distributed in the North Pacific with largest concentrations found in the eastern Bering Sea. While related to the common Atlantic pollock species of the same family, the Alaska pollock is not a member of the same Pollachius genus. Rather, recent research suggests that it is more closely related to Atlantic cod, and that Alaska pollock should be moved back to genus Gadus in which it was originally described as Gadus chalcogrammus. Furthermore, Norwegian pollock (Theragra finnmarchica), a rare fish of Norwegian waters, is likely the same species as the Alaska pollock.
