| 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 Fcur/F0.1: Ratio between the observed fishing mortality coefficient during the last year of the series and F0.1. 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 the current biomass level. Fcur/FMSY: Ratio between the observed fishing mortality coefficient during the last year of the series and the coefficient that would give a maximum sustainable yield over the long term. Bcur/B0.1: Ratio between the estimated biomass for the last year and the biomass corresponding to F0.1. Bcur/BMSY: Ratio between the estimated biomass for the last year and the biomass corresponding to FMSY. Unless otherwise indicated, the indicators were based on the Schaefer dynamic production stock assessment model. Habitat Bio Climatic Zone: Tropical. Vertical Dist: Demersal.

Bio Assess Assessment year: 2011 The CECAF Working Groups have adopted the following Biological Reference Points (BRPs): - Limit Reference points: BMSY and FMSY - Target Reference Points: B0.1 and F0.1 Stock status is assigned based on current estimates of fishing mortality (Fcur) and biomass (Bcur) relative to these target and limit reference points (Bcur/BMSY, Fcur/FMSY, Bcur/B0.1, Fcur/F0.1). The results from the stock assessment of this stock are found under the “Biological state and trend section”. Assess Models Type: Biomass-aggregated Schaefer dynamic production model To apply the data, the total catches of Guinea-Bissau and Guinea for the period 1995–2008 were used. The catches of Guinea-Bissau were estimated8 for the periods 1998-1999 and 2002-2004. The abundance indices used were the CPUE of industrial demersal fish in Guinea. The initial input parameters were: r (intrinsic growth rate) = 0.90; K (initial biomass) = 30 000 tonnes and BI/K (biomass of the stock at the beginning of the series of data, compared with the initial biomass) = 70 percent. Results The model provides a satisfactory fit to the data. The results indicate that the stock is not fully exploited. Sci Advice As a precautionary measure, the Working Group recommends that the fishing effort should be closely monitored. Management Management unit: Yes Sources FAO. 2016.
