| Main Descriptors | Considered a single stock: Yes
Spatial Scale: Regional
Management unit: Yes
Reference year: 2020
|
| 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 Assessment of the Patagonian toothfish (D. eleginoides) in Subarea 48.3 indicates that the current status of the stock is at 50% of B0. Spawning biomass has been relatively constant in recent years (WG-FSA-19/28). Habitat and Biology Climatic zone: Polar. Depth zone: Abyssal ( >1000m). Horizontal distribution: Oceanic. Vertical distribution: Demersal. Geo References  | | Geographic extent of Patagonian toothfish - South Georgia

Assessment Assessments are reviewed biennially, the last assessment was in 2019. Assessment Model Type: Age-structured CASAL The stock of D. eleginoides in Subarea 48.3 is assessed using an age-structured, two-fleet, CASAL integrated stock assessment model.
