Assessment
 

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

For the Senegal-Gambia stock, the data series for the total catch of squid from 1990 to 2012 was used in the model. The abundance indices (CPUE) of the Senegalese industrial fleet were used.
Overall Assessment Results

Tests were done with a long series (1990-2012) and a short series (2004-2012). The short series gave the best fit. However, due to the very low catches, the results of the model were inconclusive according to the Working Group.
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.
