The fisheries


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.


Assessment
 
Scientific Advice

ICES advises on basis of the precautionary approach that there should be no fishing on this stock.
Assessment Model

Scientific basis

Assessment type Gadget age–length-structured model.
Input data 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
(BS-NoRu-Q1-Btr).
Discards and bycatch Not available.
Indicators -
Other information Last benchmark was in February 2012 (WKRED). Assessment methodology based on Gadget was adopted.
Working group report AFWG
Management
Management unit: Yes
Biological State and Trend
Exploitation rate: Unknown
Abundance level: Unknown

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.
