Fcur/F0.1: Ratio between the observed fishing mortality coefficient during the last year of the series and F0.1.
Fcur/FMSY: Ratio between the observed fishing mortality coefficient during the last year of the series and the coefficient that would give a maximum sustainable yield over the long term.
Bcur/B0.1: Ratio between the estimated biomass for the last year and the biomass corresponding to F0.1.
Bcur/BMSY: Ratio between the estimated biomass for the last year and the biomass corresponding to FMSY.

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”.
Sci Advice

The stock was considered not fully exploited in 2021. An 8 percent decrease in catch was recorded in 2021 compared to 2020. Biomass has improved but significant catches have been recorded in recent years with the emergence of an inshore fleet in Mauritania. In this last zone, abundance indices are lacking. The average size of the sardine caught showed an overall downward trend, hence the need to be vigilant in the exploitation of this stock. This stock is strongly influenced by environmental factors and exhibits fluctuations in biomass independent of fishing. For this reason, the total allowable catch must be adapted to the natural variations of the stock. Stock structure and abundance should also be closely monitored through fishery-independent methods, such as coordinated acoustic surveys throughout the species' range.
