Atlantic ocean perch (also called redfish) swims in cold waters in the North Atlantic. Pacific rockfish, including widow, canar, chilipepper, China, vermillion, yelloweye, quillback, and bocaccio rockfish, are available on the West Coast, and are sometimes wrongly called Pacific red snapper. The scorpion fish (or sculpin) has poisonous spines that must be cut off with scissors. Rockfish are available as whole fresh fish, or as frozen fillets.
