Exploitation rate is higher than the Patterson’s reference point (E=0.50). *The ratio E/Eunique refers to the the ratio between the current exploitation rate (E = F/(F+Z)) and the target exploitation rate, which according to the above mentioned framework is set to E = 0.4.

State-space stock assessment model (SAM)

SAM tuned by acoustic

The WGSASP [Working Group on Stock Assessment of Small Pelagic Species] agreed in the improvements of some parameters in the assessment respect to last year: in particular, the Fbar was set equal to 1-2, the plus group was set at age 4+. The results are consistent with last year estimations from SAM model. Due to unclear historical perspective, reference points cannot be updated. Advice is therefore provided on a precautionary basis (exploitation rate and biomass percentiles). WGSASP recommended a revision of the input-basic data (e.g. age structure) including testing the use of recent biological data (length structure and ALKs) from the eastern area in the older part of the eastern landings time series.
