Afficher plus [+] Moins [-]Long term trends in the variation of reproduction parameters can be indicative of a change in the life-history traits of the species and could have consequences for survival (i.e. natural mortality) and condition, and ultimately affect recruitment success and population growth and persistence. In this deliverable we analysed potential historical changes in reproduction parameters calculated for the reproduction period, gonadosomatic index (GSI) and size at first maturity (L50) of European sardine and anchovy from GSA06 (Northern Spain) and GSA01 (Alboran Sea). In the case of European sardine, GSA06 data was divided in two subareas, GSA6 north (data from Tarragona harbour) and GSA06 south (data from Torrevieja harbour). Results are compared with previous historical analysis on GSA07 (Gulf of Lions, Brosset et al., 2016) and with the information gathered from the review performed under SPELMED and presented in deliverable D1.3.2.2.
