| Main Descriptors | Considered a single stock: No Spatial Scale: Regional
Management unit: Yes Reference year: 2010
|
| 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. |
| | | | | | Biological State and Trend Habitat and Biology Climatic zone: Temperate. Bottom type: Unspecified. Depth zone: Slope - Deepslope (500 m - 1000 m). Horizontal distribution: Neritic; Oceanic. Vertical distribution: Demersal/Benthic. Geographical Distribution Jurisdictional distribution: Straddling between High Seas and EEZ The Fisheries Commission adopted in 2010 an MSE approach for Greenland halibut stock in Subarea 2 + Division 3KLMNO (FC Working Paper 10/7). This approach considers a survey based harvest control rule (HCR) to set a TAC for this stock on an annual basis for the next four year period.

The following area codes have been found as intersecting the distribution of Greenland halibut - Labrador Shelf, Northeast Newfoundland Shelf, Northern Grand Bank Resource Structure Considered a single stock: No Assessment Data Survey slopes were computed over the most recent five years (2006-2010) and are illustrated below. The data series included in the HCR computation are the Canadian Autumn Div. 2J3K index (“F2J3K”), the Canadian Spring Div. 3LNO index (“S3LNO”), and the EU Flemish Cap index covering depths from 0-1400m (“EU1400”). Averaging the individual survey slopes yields slope= -0.1130. Assessment Model Analytical assessment Results Therefore, 17185*[1+2*(-0.1130)] = 13 301 t. However, as this change exceeds 5%, the HCR constraint is activated and TAC 2012 = 0.95*17185=16 326 t. Management Management unit: Yes Div. 3LMNO only |
