Rose Fish

The Icelandic rose fish fishery has been MSC-certifiedMSC Certified:
Fisheries that comply with the Marine Stewardship Council assessment criteria and are certified. Fish products with the blue MSC label are caught by sustainable fisheries. in 2014. The management in the Icelandic fishery zone is better done than the other catching areas. The fishery uses several methods: [bottom otter trawl], [Danish seine], gillnetsGillnets:
A fishing technique whereby passing fish get caught in the meshes with their gills. The net stands vertically on the bottom or hangs on buoys in the water column. The by-catch of species such as porpoises and dolphins is a problem related to gillnets., longlinesLonglines (drifting):
A fishing method whereby a long main line (40-100 km long) with transverse lines with hooks with bait is expanded. The line floats on buoys in the water column.  and handlinesHandlines and pole-lines:
A collective name for pole lines, jigs and troll lines. Hand lines and pole lines are used on a small scale most of the time and are relatively selective. unwanted by-catch have a high survival rate because they can be thrown back immediately.  .

The stock of rose fish in the Barents Sea is overfishedOverfished:
A stock is overfished when the stock size has decreased 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 stock is on the lowest level ever. The [fishing pressure] is much too high. Rose fish is very vulnerable to fishing pressure because the grow slowly and reach sexual maturity only after ten years.

Rose fish is a deep-sea species and often resides between centuries old cold-water corals. These corals have a great risk of being destroyed by bottom trawls. In some areas, mainly around Norway, the coral areas are closed for bottom trawls.

The management is largely effective. It is difficult for the management to differentiate between the two species of redfish. Two species of redfish are living in overlapping areas. In certain areas there are no separate [catch limit] for both species, and they are not differentiated when landed. According to ICESICES:
International Council for the Exploration of the Sea, an international organization dedicated to research and advice for a sustainable use of the oceans. , the fishery on redfish in the Barents Sea should be fully closed.

Rose fish is a deep-sea species and often resides between centuries old cold-water corals. It is unknown if the [gillnet fishery] damages these vulnerable habitats. In some areas, mainly around Norway, the coral areas are closed for bottom trawls. There is much 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).  of rose fish in the Russian pelagicPelagic trawls:
In pelagic trawling, a trawl is pulled through the water column. The net is not towed across the seabed. fishery.

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.
