The turbot (English: /ˈtɜːrbət/TUR-bət, French: [tyʁbo].;[2]Scophthalmus maximus) is a relatively large species of flatfish in the familyScophthalmidae. It is a demersal fish native to marine or brackish waters of the Northeast Atlantic, Baltic Sea and the Mediterranean Sea. It is an important food fish.[3] Turbot in the Black Sea have often been included in this species, but are now generally regarded as separate, the Black Sea turbot or kalkan (S. maeoticus).[4] True turbot are not found in the Northwest Atlantic; the "turbot" of that region, which was involved in the so-called "Turbot War" between Canada and Spain, is the Greenland halibut or Greenland turbot (Reinhardtius hippoglossoides).[5]
