Report on stock status and reference points

The status of the sardine and anchovy stocks in GSA 06 and GSA 07 were investigated using statistical catch-at-age (a4a) and two-stage biomass models. Life-history parameters of both species were reviewed and new estimates of the von Bertalanffy growth parameters (improving the value of t0) were used. The input data to the stock assessment model were updated, as required (including the natural mortality parameter, M). The new estimates for the growth parameters were for European sardine: Linf = 20.1 cm TL, k = 0.817 yr-1, t0 = -0.246 yr, and for European anchovy: Linf = 18.0 cm TL, k = 0.984 yr-1, t0 = -0.255 yr.
