| 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. Unless otherwise indicated, the indicators were based on the Schaefer dynamic production stock assessment model. Habitat Bio Climatic Zone: Tropical.

Bio Assess Assessment year: 2014 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 The time series of total catches of anchovy (Engraulis encrasicolus) for Benin, Côte d’Ivoire, Ghana and Togo from 1990 to 2012 were used for the production model. The abundance indices used to adjust the model are the CPUEs from the artisanal fisheries in Ghana and Togo. The initial parameters used for the assessment model were: - Engraulis encrasicolus: r = 3.00, K = 148 009 tonnes and BI/K = 65 percent. Results The model gave reliable results with the abundance indices of Ghana and Togo. The two CPUEs represent the abundance variability estimated by the model during these years (Figure 4.6.1 of FAO, 2015). As the results obtained are similar to the two CPUEs, the Working Group decided to maintain the results estimated with the CPUE from Togo for continuity in the 2009 assessment, and as a precautionary measure. The results show that the current biomass is 85 percent of the corresponding biomass at B0.1, and the fishing mortality observed in 2012 is 53 percent of the fishing mortality F0.1. From this assessment, it appears that the stock is fully exploited. Sci Advice Catch level should not exceed the average level of the 3 last years (56 000 tonnes).
