In these groups we include other fleets targeting Penaeus notialis, which were not considered in Section 6.3 of FAO, 2015, because the catch data available comprise a sum of species captured in the same zones and with the same fishing gears, but the catches have not been separated into species. The main species are Parapenaeopsis atlantica, Penaeus notialis and P. monodon combined. The Penaeus notialis is the most important species.

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

The total catch and the CPUE of the Congolese artisanal fleet were used.
Overall Assessment Results

The model is fitted to the data available. The Working Group has decided that the results are not realistic and rejects the assessment.
Scientific Advice

The data provided to the Working Group for the Democratic Republic of Congo was insufficient to allow any analysis.
