| 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. |
| | | | | | Aq Res State Trend There is a high probability (76%) that the stock was not overfished and no overfishing was taking place in 2020. Habitat Bio Climatic Zone: Temperate.

Bio Assess Uncertainty: Low Assessed Data Time series of fishing effort, i.e.number of hauls and catch (kg) from 2000 to 2020 from logbook records, annually aggregated length frequency data from 2011 to 2020, acoustic biomass indices from 2004 to 2018, and age composition data from the catch of 2017. Assess Models Type: Others CASAL Integrated stock assessment Results There is a high probability (76%) that the stock was not overfished and no overfishing was taking place in 2020. Sci Advice The exploitation on Walter’s Shoal Ridge and the larger Long Walter’s Shoal Ridge was well within sustainability limits while the exploitation in the Southwest Indian Ridge is too close to limit harvest rates (MSY).
