Plaice
Plaice is a common name for a group of flatfish that comprises four species: the European, American, Alaskan and scale-eye plaice.
Commercially, the most important plaice is the European. The principal commercial flatfish in Europe, it is also widely fished recreationally, has potential as an aquaculture species, and is kept as an aquarium fish. The American plaice is also commercially important.
The term plaice (plural plaice) comes from the 14th-century Anglo-French plais. This in turn comes from the late Latin platessa, meaning flatfish, which originated from the Ancient Greek platys, meaning broad.
The European plaice (Pleuronectes platessa) is a right-eyed flounder belonging to the family Pleuronectidae. It is a commercially important flatfish that lives on the sandy bottoms of the European shelf. It ranges geographically from the Barents Sea to the Mediterranean. European plaice are characterised by their smooth brown skin, with distinctive red spots and a bony ridge behind the eyes. They feed on polychaetes, crustaceans and bivalves and can be found at depths of up to 200 metres. At night they move into shallow waters to feed and during the day they bury themselves in the sand. Their maximum recorded length is 100 cm (39 in) and maximum reported age 50 years.
Together with sole, European plaice form a group of flatfish that are the most important flatfish in Europe. European plaice have been fished from the North Sea for hundreds of years. They are usually fished from beam trawlers, otter trawlers or seiners. In the Celtic Sea the plaice species is considered overfished.
Like the European plaice, the American plaice is a right eyed flatfish belonging to the family Pleuronectidae. American plaice are an Atlantic species, which range from southern Labrador to Rhode Island. They are also found in Europe, where they are called rough dab or long rough dab. They spawn in the Gulf of Maine, with peak activity in April and May. They are brown or reddish, and are generally smaller than European plaice, with a rougher skin and larger scales. Their maximum recorded length is 82.6 cm (32.5 in), and maximum reported age 30 years. They are usually found between depths of 90 and 250 m (300 and 820 ft) on sandy bottoms with temperatures between −0.5 and 2.5 °C (31.1 and 36.5 °F). They feed on small fishes and invertebrates.
The species is considered by the Northwest Atlantic Fisheries Organization to be overfished, with no signs of recovery. Though they are also currently endangered in Canada due to overfishing, the Canadian government believes the species is abundant. Flatfish, as a group, are second-most caught (by weight) only to cod in Canada, with American plaice accounting for 50 percent of all flatfish caught.
American plaice may be an intermediate host for the nematode parasite Otostrongylus circumlitis, which is a lungworm of seals, primarily affecting animals less than 1 year of age.
