Arctic cod (Boreogadus saida) in fjord and glacial habitats: a collaborative study with Uummannap Kangerlua fishers
Arctic cod (Boreogadus saida) (Lepechin, 1774) is often found in front of glaciers, which is the least studied of the species’ habitats. Uummannap Kangerlua and Sullorsuaq in West Greenland provide a unique opportunity to study Arctic cod in the glacial habitat, as they are among the few places with...

Arctic cod (Boreogadus saida) (Lepechin, 1774) is often found in front of glaciers, which is the least studied of the species’ habitats.

Inuit fishers from these fjords regularly catch Arctic cod as fresh bait for the Greenland halibut (Reinhardtius hippoglossoides) (Walbaum, 1792) longline fishery, the main economic activity in the region. We collaborated with the fishers to learn about Arctic cod through interviews and collection of fish samples.
