Atlantic halibut (Hippoglossus hippoglossus) is a saltwater species recorded in the United States. It is found at depths of 50–2000 m.
Scientific name: Hippoglossus hippoglossus · Water: Saltwater
Size: up to 470 cm
The Atlantic halibut is a demersal pleuronectid whose adults are benthic but occasionally pelagic, feeding mainly on other fishes such as cod, haddock, pogge, sand-eels, herring and capelin, as well as on cephalopods, large crustaceans and other bottom-living animals; it is a batch spawner. Growth rate varies with density, competition and food availability, and its slow growth and late maturity mean that populations can be seriously affected by overfishing. It is recorded from 50 to 2,000 m. Its range is the Atlantic Ocean and adjacent Arctic. Maximum length is about 470 cm total length, and it can live 50 years, maturing at about 122 cm. It is a commercial species, an experimental aquaculture species, a gamefish and a public aquarium fish, with a very high price category. Fishing vulnerability is very high at 88 of 100 and resilience very low, and climate vulnerability is moderate at 43 of 100. IUCN lists it as near threatened.
