Bio Assess
Assessment year: 2021
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”.
Results
Stock seems to be in good condition, but assessments were accepted with caution because of low fit of the model.
Sci Advice
The Working Group recommends that the catch should not exceed the mean catch of the last five years (400 tonnes). This should be considered with caution due to the lack of artisanal fishery information and incomplete or not accurate data from some industrial fleets.
