Abstract[EN] With data on age composition and fishing effort of the Castellón sardine (Sardina pilchardus) population from 1956 to 1969 regression lines between total mortality and effort are calculated. Also approaches of Taylor, Beverton and Rikhter and Efanov to estimate M are used. Natural instantaneous mortality rate seems to be high and in the range of 0.8 to 1.0
[FR] On a calculé des régressions entre la mortalité totale et l'effort de pêche dans la population de sardine (Sardina pilchardus) de Castellón avec des données sur la composition en âge et l'effort depuis 1956 jusqu'à 1969. Nous avons employé aussi les formules de Taylor, Beverton et Rikhter et Efanov pour l'estimation de M. Le coefficient instantané de mortalité naturelle est environ de 0,8 à 1,0
