There are three stocks in this origin: Disko Bay, Uummannaq, Upernavik which are generally stable apart from Disko Bay, where the stock there shows an overall declining trend. However, with decreasing catch per unit effort (CPUE) an indirect measure of the abundance of a target species, the stock shows clear signs of overfishing.
Demersal longlines pose high risks for seabirds and demersal sharks and rays due to the baits on the hooks. Bycatch of non-endangered, non-threatened, non-protected species is considered low. Fishery discard is not allowed in Greenland waters. The effect of this fishery on the ecosystem is unknown. Habitat damage caused by longlines are reportedly moderate.
The management is considered partly effective. Measures pertaining directly to endangered, threatened, protected (ETP) species are not in place. Regulations are in force to protect vulnerable habitats in Greenland’s waters. Monitoring is effectively implemented and fisheries activity is effectively controlled within Greenland's Exclusive Economic Zone (EEZ). Fishery policies are largely transparent and stakeholder participation is enforced.
