Greenland halibut is a slow growing species and is therefore vulnerable to high [fishing pressure]. The stock size in Iceland is at the minimum level. Fishing mortality has decreased but is still too high.
Greenland halibut is bycatchBycatch:
Species caught next to species targeted for fishery. By-catches can consist of non-commercial species and species that are too small, and can be kept (this part is sometimes called by-product) or thrown back into the sea (discards). in the mixed [Danish seine] fishery. Bycatch in this fishery is low and discarding of bycatch is forbidden in Iceland. There is damage to the seabed.
The management system for this fishery is largely effective but is not considering the whole ecosystem sufficiently.
