| Main Descriptors | Considered a single stock: No Spatial Scale: Regional
Management unit: Yes Reference year: 2014
|
| Considered a single stock: A group of individuals in a species occupying a well defined spatial range independent of other stocks of the same species. It can be affected by random dispersal movements and directed migrations due to seasonal or reproductive activity. |
| Spatial Scale: Spatial scale contains a standard term such as Global, Regional (e.g. for the whole Atlantic), sub-regional (e.g. for a part of the Atlantic), national, local (for sub-national levels). |
| Considered a management unit: An aquatic resource or fishery is declared as [Fishery] Management Unit if it is effectively the focus for the application of selected management methods and measures, within the broader framework of a management system. According to the FAO Glossary for Responsible Fishing, "a Fishery Management Unit (FMU) is a fishery or a portion of a fishery identified in a Fishery Management Plan (FMP) relevant to the FMP's management objectives." FMU's may be organised around fisheries biological, geographic, economic, technical, social or ecological dimensions , and the makeup and attribute of a fishery management unit depends mainly on the FMP's management objectives. |
| Jurisdictional distribution: Jurisdictional qualifier (e.g. "shared", "shared - highly migratory") of the aquatic resource related with its spatial distribution. |
| Environmental group: Classification of the aquatic resource according to the environmental group (e.g. pelagic invertebrate, or demersal fish) to which the species belong. |
| Reference Year: The Reference Year is the last year considered in the stock assessment and/or fishery status. |

The following area codes have been found as intersecting the distribution of Redfish - Flemish Cap Resource Structure Considered a single stock: No 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 | | STATLANT 21 | 6.3 | 5.6 | 7.9 | 8.7 | 8.5 | 9.7 | 6.7 | 6.8 | 6.5 | | | STACFIS | 7.2 | 6.7 | 8.5 | 11.3 | 8.5 | 11.1 | 7.6 | 7.8 | 7.5 | | Effects of the fishery on the ecosystemAssessment Overall Assessment Results Reference Point No updated information on biological reference points was available. Assessment Model Analytical assessment 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. Fishing MortalityRecruitmentBiomassHuman impactMainly fishery related mortality. Other sources (e.g. pollution, shipping, oil-industry) are undocumented. Biological and environmental interactionsScientific Advice Special Comments Management Management unit: Yes Management Advice Recommendation for 2016 and 2017Recent 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.
