| Main Descriptors | Considered a single stock: Yes Spatial Scale: Regional
Management unit: Yes Reference year: 2018
|
| 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 Biomass estimated at 53124 tonnes. Habitat and Biology Climatic zone: Polar. Depth zone: Shelf (50 m - 200 m); Slope - Upperslope (200 m - 500 m).

Assessment Assessments are reviewed biennially, the last assessment was in 2019. Assessment Model Type: Size-structured Length-based The use of a length-based model to set catch limits for C. gunnari in Subarea 48.3 was endorsed at the 2010 meeting of the Working Group on Fish Stock Assessment (WG-FSA-10) (SC-CAMLR-XXIX, Annex 8, paragraph 5.164). The assessment used survey data on length densities and biomass density without the need to identify age-specific cohorts. Scientific Advice A stratified bootstrap of icefish catch density based on the UK 2019 demersal fish survey catch rate data indicated a biomass of 53,124 tonnes (lower one sided 5th percentile: 32,399 tonnes) within Subarea 48.3 (WG-FSA-2019/30). Projections for the 2019/20 and 2020/21 seasons applying the CCAMLR harvest control rule lead to catch limits (TAC) of 3,225 tonnes for 2019/20 and 2,132 tonnes for 2020/21.
