Assessment
 

Assessment year: 2014
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 input data prepared by the FAO/CECAF Working Group on the Assessment of Small Pelagic Fish Subgroup South were the total catch data on Trachurus trecae from the artisanal, inshore and industrial fisheries for the period 1990–2012 for the four countries. The CPUEs from Ghana’s inshore fishery and artisanal fishery were used in the stock assessment model.
Overall Assessment Results

The assessments did not provide any reliable results as the model did not adjust well to the data available. It was, however, noted that a general decrease in catches could be observed over the last five years.
Scientific Advice

Catches decreased over the last 5 years. As a precautionary measure, do not increase catches of this species from the average of the 5 last years (12000 tonnes).
