Biological State and Trend
State & Trend Descriptors
Exploitation rateFcur/F0.1 = 37% ; Fcur/FMSY = 34%Not applicable
Abundance levelBcur/B0.1 = 146% ; Bcur/BMSY = 160%Not applicable
FAO Categories
Exploitation stateNot fully exploited

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 data series for the total catch of squid in the Cap Blanc zone was used in the model for the period 1990-2012. The CPUEs of Mauritanian ice trawlers were used as abundance series for the model fit.
Scientific Advice

Considering that this species is caught by the same fleets targeting octopus and cuttlefish, the same recommendations made for octopus and cuttlefish are also valid for the loligo fishery.
