On the Fishery Potential of the Sea Waters of the Canadian North

The fishery potential of water originating in the Arctic Ocean is negligible, not because of water temperature or light penetration, but because of its vertical stability which keeps nutrients near the bottom. The subarctic mixed water is very productive. The marine subarctic zone on the Atlantic si...

Description
Summary:The fishery potential of water originating in the Arctic Ocean is negligible, not because of water temperature or light penetration, but because of its vertical stability which keeps nutrients near the bottom. The subarctic mixed water is very productive. The marine subarctic zone on the Atlantic side includes Ungava Bay, Labrador coast, Newfoundland waters and the north part of the Gulf of St Lawrence. The very low abundance of fish in Hudson Bay is briefly discussed and notes given on the appearance, economic importance, geographic ranges and uses of some 20 species incl- uding shrimp, crab, mussel, clam and squid. Sur le potentiel de pêche des eaux marines du Nord canadien. Dans les eaux arctiques (originaires de l'océan Arctique), le potentiel de la pêche est négligeable. Le Subarctique, région d'eaux mixtes, est beaucoup plus productif et alimente déjà des pêcheries maritimes. Pour satisfaire aux demandes du marché actuel, il y a un besoin pressant de méthodes modernes de traitement du poisson. On attire ici l'attention sur les possibilités qu'offrent certaines espèces, comme le requin du Groënland, le flétan du Groënland, le capelan, le sébaste et la crevette. On insiste sur l'importance des changements du climat marin.
