| 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. |
| | | | | | Habitat Bio Climatic Zone: Tropical. Bottom Type: Hard rocky bottom; Soft bottom clean sand. Depth Zone: Coastal (0 m - 50 m); Shelf - Uppershelf (up to 100 m). Horizontal Dist: Littoral. Vertical Dist: Demersal/Benthic. Red pandora is found both on hard and sandy bottoms, in particular in depths of more than 100 m. They are omnivores with a mainly carnivore diet including crustaceans, cephalopods, small fish, amphioxus and worms. In the East Atlantic the species is distributed from the Straits of Gibraltar to Angola, including the southwest Mediterranean and Canary Islands.

Water Area OverviewRed Pandora - Morocco, Mauritania, Senegal and Gambia Aq Res Struct Biological Stock: Yes The Working Group considered a single stock exploited by the industrial and artisanal fisheries over the whole zone. However, given its importance in each country, the Working Group decided to carry out an analysis by management unit (Mauritania, Senegal and The Gambia). Bio Assess Data The total catch series of Pagellus bellottii over the whole northern CECAF zone (Mauritania, Senegal and The Gambia) was used. For the abundance indices series, after several attempts with various abundance series (ice canoes, Mauritanian national cephalopod trawlers), the Working Group decided to use the CPUE series of the motorized line canoes from the Senegalese artisanal fishery.
Assess Models Type: Biomass-aggregated The Schaefer dynamic production model implemented on an Excel spreadsheet was used to assess the state of the Pagellus bellottii fishery stock (FAO, 2007). Results The model gives a satisfactory fit to the data.
Current biomass is below that corresponding to the B0.1 biomass. Current fishing effort is greatly above that producing a sustainable yield at current biomass levels (Table 1).

Fcur/FSYcur: Ratio between the observed fishing mortality coefficient during the last year of the series and the coefficient that would give a sustainable yield at current biomass levels.
Bcur/B0.1: Ratio between the estimated biomass for the last year and the biomass corresponding to F0.1.
Fcur/F0.1: Ratio between the observed fishing mortality coefficient during the last year of the series and F0.
Bcur/BMSY: Ratio between the estimated biomass for the last year and the biomass coefficient corresponding to FMSY.
Fcur/FMSY: Ratio between the observed fishing mortality coefficient during the last year of the series and the coefficient giving maximum long term sustainable yield.
The stock is heavily overexploited. This conforms with the drop or even collapse of the abundance indices measured in Mauritania by the R/V AL-AWAM. On the other hand, the increase in CPUEs of the ice canoes in Senegal could be explained by the enlargement of their fishing zone outside of Senegal towards countries to the south. Sci Advice for Management considerationsAs during the previous Working Group, it is recommended that fishing effort be reduced for all demersal fisheries.
