Assessment
 

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”.
Overall Assessment Results

No assessment was made as no CPUE series were available. Catches showed a stable trend in the last years. 
Scientific Advice

As a precautionary measure, do not exceed the average of the 5 last years (14 000 tonnes).
