Biological State and Trend
SSB has been decreasing since the 1990s and is currently at the lowest level in the time-series. Fishing mortality has been increasing since 2005 and is currently at the highest level in the time-series. Recruitment is very low.
Habitat and Biology
Depth zone: Shelf (50 m - 200 m). Vertical distribution: Pelagic.
Jurisdictional distribution: Shared between nations
Water Area Overview
Spatial Scale: Sub-Regional
Ecoregion: Barents Sea and Norwegian Sea
Considered a single stock: Yes
Sebastes marinus is fished both in a directed gillnet and longline fishery and as bycatch in trawl fisheries targeting cod and saithe. All directed fishery except by handline is closed in the period 20 December-31 July and in September. Directed trawl fishery is not allowed. There are regulations on minimum size and on the percentage of allowed bycatch of S. marinus when fishing for other species.
|Catch distribution ||Commercial landings (2011) are 5.8 kt, of which 37% are taken by trawl, 39% by gillnet, 22% by longline, and 2% by other gears. |
ICES advises on basis of the precautionary approach that there should be no fishing on this stock.
