| 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. |

Water Area OverviewWest African croakers - Senegal and Gambia Aq Res Struct Biological Stock: Yes Croakers are mainly distributed and exploited in the southern part of the region: Senegal and The Gambia. The Working Group thus decided to consider them as a shared stock between these two countries and to assess them as a single stock.

Bio Assess Assessment year: 2013 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 data used for the model were the total catch data of the series 1990-2012 of Pseudotholitus spp. from The Gambia and Senegal. The CPUEs of the different segments of industrial and artisanal fleets were tested. Results Despite the repeated tests with different data sets available during the Working Group, the model provides a poor fit. None of the results obtained with the various data sets was conclusive. Sci Advice The assessment not being conclusive due to insufficient catch and effort data available to the Working Group, a precautionary approach is recommended and the fishing mortality should not exceed the 2012 level.
