EVALUATION DU STOCK DE LA SARDINELLE RONDE ZONE NORD – OUEST AFRICAINE PAR LA MÉTHODE CMSY

Abstract

Le taux élevé en protéine et en graisse font de cette espèce le choix privilégié des fariniers depuis 2013. Malgré, l’augmentation de l’effort de pêche, les captures ont commencé à chuter depuis 2014 annonçant ainsi le début de la surexploitation de ce stock. Du fait de la discontinuité des séries d’indices d’abondance pour la sardinelle, le modèle de surplus de production utilisé antérieurement pour fournir un avis de gestion n’a cette année encore pas pu être appliqué. Afin d’estimer les points de référence pour la sardinelle, de donner un diagnostic sur l’état des stocks, une approche basée sur les données de captures uniquement, CMSY (Froese et al. 2017), a été considérée. Depuis 2016, le stock de la sardinelle ronde n‘a pas été évalué par le groupe COPACE faute de données. Cette situation de manque de données fait de cette espèce un stock à données limités d’où le choix du modèle CMSY.
