Aq Res State Trend
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.
Habitat Bio
Climatic Zone: Tropical. Depth Zone: Coastal (0 m - 50 m); Shelf (50 m - 200 m); Slope - Upperslope (200 m - 500 m). Vertical Dist: Demersal.
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
As a precautionary measure the working group recommends that catch does not exceed the average of the last 5 years (1620 tonnes).
