Main Descriptors | Considered a single stock: Yes
Spatial Scale: National Management unit: Yes
Reference year: 2008
|
Considered a single stock: A group of individuals in a species occupying a well defined spatial range independent of other stocks of the same species. It can be affected by random dispersal movements and directed migrations due to seasonal or reproductive activity. |
Spatial Scale: Spatial scale contains a standard term such as Global, Regional (e.g. for the whole Atlantic), sub-regional (e.g. for a part of the Atlantic), national, local (for sub-national levels). |
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. |
| | | | Biological State and Trend Habitat and Biology Climatic zone: Tropical. Bottom type: Soft bottom muddy or muddy-sand. Depth zone: Coastal (0 m - 50 m); Shelf - Uppershelf (up to 100 m). Horizontal distribution: Littoral. Vertical distribution: Demersal/Benthic.

Assessment 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”. Assessment Model Type: Biomass-aggregated Schaefer dynamic production model For the catch data series, the Working Group used the series of total catch estimated for the country, for the period 1995 to 2008 (shrimpers and other trawlers). For the abundance index, the CPUE series from the Guinean shrimp trawl fleet was used. The Working Group considered that this series best reflects the trends in abundance of Penaeus notialis in Guinea. Overall Assessment Results The fit of the model to the data is not acceptable, and therefore, no conclusions can be made based on the model results. The trends for observed and predicted CPUE reveal strong fluctuations and inconsistencies with the catches, and a decline in stock abundance in the three last years. Doubts were raised about the fishing strategy. There are strong differences in the results from the last Working Group. Given the uncertainties about the exploitation of this stock, the assessment was not accepted.
