The halibut is also in cultivated variety. Because the wild population is heavily exploited, the cultivated variety is a welcome addition. For the breeding, the Atlantic halibut is mainly used and it is the Norwegians who are advanced with the breeding of these fish. The cultured variant is significantly fatter than the wild halibut. The top of the fish is often colored dark green. The bottom of the cultured halibut is white/cream colored with often dark spots. This while the wild variant is even white at the bottom. You can clearly see the difference, but what about offering these fish in fillet form? One must be a knower to see. The structure of cultivated specimens is a little shorter and more compact compared to the wild fish.
