The Atlantic halibut – hippoglossus hippoglossus is one of our most famous fishes and one that divers come to see for themselves. The halibut is among the largest bony fishes in the world, they are strong swimmers and are able to migrate over long distances. They live usually on the bottom, between 50 to 2.000 meters depth but occasionally comes up to the surface. They eat cod, haddock, herring, octopus, large crustaceans and occasional sea bird.
A halibut can be up to 3,5 meters long and up to 300 kg. It is only the female that gets this big the male never gets bigger then 50 kg. The mature very slow and it can take 7-9 years before they reach sexual maturity, and we believe they can be up to 50 years old.
The halibut is due to its slow growth sensitive to overfishing and have since 1996 been on the IUCN rating as Endangered specie and placed on its Red List.
In Saltstraumen we have dive sites where we can see them shallower on a regularly basis, which makes us rather unique.
