Appearance. Atlantic halibut (Hippoglossus hippoglossus) is a marine, cold-water flat fish that is farmed in Canada, Iceland, the UK and Norway. The halibut's coloration, which occurs only on the eyed side of the body, varies from greenish brown to very dark chestnut brown. It is highly prized at markets worldwide, but availability of wild Atlantic halibut is decreasing and the fish is classified as endangered on the IUCN red list. The annual DFO Scotian Shelf groundfish research vessel (RV) trawl survey has been conducted every year since 1970. Recapture results indicate Atlantic halibut move extensively throughout the Canadian North Atlantic, including well outside of Canada's Economic Exclusion Zone.
