| Main Descriptors | Considered a single stock: Yes
Spatial Scale: Sub-Regional
Management unit: No
Reference Year: 2008
|
| 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 last year considered in the assessment. |
| | | | | | Habitat and Biology Depth zone: Shelf (50 m - 200 m); Slope (200 m - 1000 m). Vertical distribution: Demersal/Benthic. Geographical Distribution Jurisdictional distribution: Straddling between High Seas and EEZ Water Area Overview Spatial Scale: Sub-Regional Geo References  | | Geographic extent of Picked dogfish - Northeast Atlantic

Resource Structure Considered a single stock: Yes Management Management unit: No Management Advice Management considerationsThe advice for 2009 is biennial and valid for 2009 and 2010 and is cited in the text table below (see ICES. 2008. Report of the ICES Advisory Committee, 2008. ICES Advice, 2008. Book 9. 345 pp.)
| Spurdog (Squalus acanthias). |
All areas |
The only new information that is available for spurdog (Squalus acanthias) is landings data which does not give reason to change the advice from 2006. The advice for 2009 and 2010 is therefore the same as the advice given in 2006: “The stock is depleted and may be in danger of collapse. Targeted fisheries should not be permitted to continue, and by-catch in mixed fisheries should be reduced to the lowest possible level. The TAC should cover all areas where spurdog are caught in the northeast Atlantic and should be set at zero (...).” |
