Exploitation
 

Redfish is caught primarily in bottom trawl fisheries, but some landings are reported from fisheries with mid-water trawl. Cod is the main bycatch species in shallower waters, and Greenland halibut in deeper waters. In turn, redfish are also caught as bycatch in fisheries directed for cod and Greenland halibut. The fishery in NAFO Div. 3M is regulated by minimum mesh size and quota.

Recent catch estimates and TACs (000 t) are as follows:
  2006 2007 2008 2009 2010 2011 2012 2013 2014 2015
TAC 5 5 5 8.5 10.0 10.0 6.5 6.5 6.5 6.7

Results

Input data comes from EU Flemish Cap bottom trawl survey and the fishery (STACFIS 2015) and is considered good quality. A quantitative model (XSA) introduced in 2003 was used (STACFIS 2013). Model settings were in general kept unchanged from last assessment, with a natural mortality at 0.4 through 2006-2010, declining on 2011 and 2012 to 0.125. The magnitude of beaked redfish natural mortality (M) between 2013 and 2014 has been analysed on the sensitivity analysis of the present assessment, pointing out to a marginal increase of M to 0.14.

The next full assessment of this stock will be in 2017.

Human impact

Mainly fishery related mortality. Other sources (e.g. pollution, shipping, oil-industry) are undocumented.

Management Advice

Recommendation for 2016 and 2017

Recent decline in proportion of S mentella and S fasciatus allows a marginal increase in TAC in 2016-17 to 7000t, without changing the exploitation rate on these species and having the stock remain at a relatively high level.
Management Objectives

No explicit management plan or management objectives defined by Fisheries Commission. General Convention objectives (GC Doc. 08/3) are applied.
