Main Descriptors | Considered a single stock: No
Spatial Scale: Regional Management unit: Yes
Reference year: 2016
|
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 nowadays caught in bottom trawl fisheries at intermediate depths. 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: Effects of the fishery on the ecosystem Assessment Overall Assessment Results Reference Point No reference points have been adopted. Projection Short term (2018-2019) stochastic projections were carried out for female spawning stock biomass (SSB) and catch, under most recent level of natural mortality and considering four options for fishing mortality (F0, Fstatusquo, F0.1 and Fmax). Projections were initialized at the beginning of 2018 assuming Fstatusquo during 2017. Recruitment entering in 2017 and 2018 is assumed constant at the geometric mean of below average recruitments (age 4 XSA, 1989-2014). In all projections scenarios spawning biomass remains at relatively high levels. Assessment Model Analytical assessment Results Input data comes from EU Flemish Cap bottom trawl survey and the fishery and is considered good quality. A quantitative model (XSA) introduced in 2003 was used. Elevated natural mortality was assumed from 2006 to 2010 but was low (more typical of redfish) otherwise. In order to include an independent approach to natural mortality in the 2017 sensitivity M framework, the actual beaked redfish natural mortality has been estimated by a number of published models The next full assessment of this stock will be in 2019.

Biological and environmental interactions Management Management unit: Yes Management Advice Recommendation for 2018 and 2019Management Objectives No explicit management plan or management objectives defined by Fisheries Commission.
