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 anchovy assessment was based on information from the North+A+B area. After examining the results of the model, the evolution of the biomass of the stock and the catches, the anchovy is considered to be fully exploited. Given that the availability of anchovy is highly dependent on environmental factors, that it is exploited opportunistically and that catches vary considerably from year to year, the Working Group recommends adjusting the effort of fishing to the natural fluctuations of this stock.
