A member of the Pleuronectidae family of right-eyed flatfish, the petrale sole is an occasional catch by anglers and a good sportfish, in part owing to its moderate size. It is an excellent food fish and is highly sought commercially, primarily by trawlers, and is marketed fresh or as frozen fillets. The livers of large specimens are known to be rich in vitamin A.

IdentificationThe body of the petrale sole is elongate, moderately slender, and compressed. The head is deep and the mouth large. The eyes are large, and the color on the eyed side is uniformly dark to light brown, with dusky blotches on the dorsal and the anal fins. It is white on the blind side.
The petrale sole is often confused with the California halibut because these species have a similar color and large mouths. The petrale sole, however, has an even, brown coloration and does not have a high arch in its lateral line.
