Exploitation stateOverexploited

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.
Unless otherwise indicated, the indicators were based on the Schaefer dynamic production stock assessment model.

Assessment year: 2013
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 series of total landings for all the fleets (coastal, deep-sea cephalopod vessels, longliners and Moroccan and Spanish artisanal fisheries) of the sea bream (Pagellus acarne) was used by the Working Group. It should be noted that the low catches over the last few years may be due to the extension of the biological rest season in recent years. The Working Group used both the abundance indices (kg/30 min) of the trawl surveys carried out between Bojador and Lagouira and the CPUEs of the national cephalopod trawlers for the model fit.
Scientific Advice

Considering that the besugue is taken as bycatch in several fisheries, it is important to monitor the application of the regulations in force in the different fisheries to ensure a stock recovery.
