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.
||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.
Assessment ModelScientific basis
||Gadget age–length-structured model.
||Catch numbers-at-age and at-length from the trawl, gillnet, and longline fisheries. Numbers-at-age and at-length from the winter survey in the Barents Sea
|Discards and bycatch
||Last benchmark was in February 2012 (WKRED). Assessment methodology based on Gadget was adopted.
