| Main Descriptors | Considered a single stock: Yes Spatial Scale: Sub-Regional
Management unit: Yes |
| 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. |
| | | | | | Habitat and Biology Depth zone: Slope (200 m - 1000 m). Vertical distribution: Demersal/Benthic.

Management Management unit: Yes Management Advice Management considerationsThis section deals with a species distributed over a wide area which may be composed of several populations. Age analyses suggest that roundnose grenadier may have a longevity of around 70 years and a slow growth. The scientific basis for stock identification is uncertain. The Wyville-Thomson Ridge and fjord sills, between Western Scotland and the edge of the North Sea slope, could be natural physical boundaries. It is therefore considered that the northern North Sea and the Norwegian Deep could represent a separate management unit (IIIa and IVa). The roundnose grenadier on the Mid-Atlantic Ridge and the Hatton Bank are separated by a major oceanic basin and may constitute separate management units. This would indicate that the management units could be split as: - Division (IIIa)
- Subareas VI, VII, and Divisions Vb, XIIb
- Mid-Atlantic ridge (Xb, XIIc, Va1, XIIa1, XIVb1)
- All other areas. (I, II, IV, Va2 VIII, IX XIVa XIVb2)
Trends in landings for all areas are shown in Figure 9.4.15.1 and Table 9.4.15.1. Biological State and Trend Exploitation rate: Undefined
Abundance level: Undefined Source of information ICES.2009.Report of the ICES Advisory Committee, 2009. ICES Advice, 2009. |
