The Greenland halibut is losing its habitat due to climate change. Fisheries and Oceans Canada are carefully monitoring the Greenland halibut populations and regulating this fishing to protect and maintain its biomass.

Greenland halibut is an oily fish. It is therefore a good source of Omega-3 fatty acids, protein, vitamin B12 and vitamin D.

Saveur riche et délicate, avec une touche de noisette. Chair blanche, floconneuse, à la fois ferme et tendre en bouche. Peu d’arêtes (parfait pour les moins initiés).


  • When fish is bought fresh, its skin should be shiny.
  • It is best to cook it quickly, at a high temperature.
  • Cold-smoked, it is delicious.
  • Marinate in a mixture of citrus fruit juice and fresh herbs.

Freezing will not alter its taste. It is, therefore, a very good conservation method.
