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/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. Habitat Bio Climatic Zone: Tropical. Bottom Type: Hard rocky bottom; Soft bottom clean sand.

Bio Assess Assessment year: 2021 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”. Sci Advice Working group recommends not to exceed 2021 catch level.
