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. Depth Zone: Coastal (0 m - 50 m); Shelf (50 m - 200 m); Slope - Upperslope (200 m - 500 m). Horizontal Dist: Neritic; Oceanic. Vertical Dist: Pelagic.

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 logistic production model Only the Congo has a series of anchovy catch data for the southern stock (Angola, the Congo, the Democratic Republic of the Congo, and Gabon) from 1998 to 2012. The other countries have sporadic data. For the model fit, the Working Group used the total catch and the abundance index, and CPUE from the artisanal fishery in the Congo. Initial parameters for the assessment model were: - Engraulis encrasicolus: r = 1.94, K = 1 500 tonnes and BI/K = 65 percent. Results Even if the results show that the stock is not fully exploited in its current state, the Working Group notes that only the Congo has data for this species and that there is a lack of data from the other three countries, although anchovy appears to be present in the whole subregion. This situation can affect the results of the assessment. The model results should therefore be considered with caution. Sci Advice As a precautionary measure, catch level should not exceed the average catches of the 3 last years (790 tonnes). Can sustain an increase in exploitation.
