The Icelandic stock of rose fish seems to increase again after a period of overfishingOverfishing:
There is so much fish caught that the size of the stock has diminished so far that it can no longer produce a maximum sustainable yield. The size of the fish populations is insufficient to reproduce in the long term. . The [fishing pressure] has decreased. Rose fish is very vulnerable to fishing pressure because the grow slowly and reach sexual maturity only after ten years. Two species of redfish occur in overlapping areas. The stock of deep-sea redfish is still not doing well.
Fishing is done with [bottom otter trawls] and [pelagic otter trawls]. Rose fish is a deep-sea species and often resides between centuries old cold-water corals. These corals are at risk of being destroyed by this fishery. There is little bycatch, but the survivability is very low because the fish don’t survive the transport from the deep-sea to the surface.
The management in the Icelandic fishery zone is better done than the other catching areas. There are for example closed nursery areas. It is difficult for the management to differentiate between the two species of redfish and they are often not differentiated when landed. In certain areas there are no separate [catch limits] for both species. There are no management agreements between the different states using this fish stock.
