The Halibut (Hippoglossus hippoglossus) grows to 100 cm.


The halibut is a large streamlined flatfish, with eyes on the right side. The upper surface is smooth, and the lateral line curves strongly over the pectoral fin.


Spawning occurs in winter in 300-1000 m of water. Females produce up to 2 million eggs. The pelagic young metamorphose before moving to the bottom in inshore waters. Halibut are sexually mature at about 10 years (100 cm).


Halibut prefer cold (3-5 degrees C) and deep water (to 2,000 m), where they hunt on the bottom or in mid-water.


Mainly other fishes, such as redfish and members of the cod family. Halibut may also feed on the bottom, taking large crustaceans.


Western Atlantic and northern North Sea.

Additional Notes[]

Halibut are very valuable commercially, but subject to overfishing. In the northern North Sea, immature individuals may turn up in the trawl, and are very occasionally taken by anglers.
