Description

American plaice is a right-eyed flatfish of the family Pleuronectidae growing to more than 80 cm. The body is elongate with a relatively large mouth, rough scales and an almost straight lateral line; the dorsal fin begins above the eye. The upper side is brown while the blind underside is white. It inhabits cold, soft bottoms across the northern Atlantic and Arctic Ocean to depths of several hundred metres, feeding on invertebrates and small fishes. A batch spawner, it releases around 50,000 pelagic eggs. Fishing pressure has sharply reduced Atlantic stocks, and the species is now assessed as Endangered.
