[EN] From data already published several population parameters for the Galicia (NW Spain) sardine are calculated. Von Bertalanffy's growth constants have been calculated as follow: L∞=230 mm, K=0,5, to=-0.96. The most likely value of the instantaneous coefficient of natural mortality has been calculated using several indirect methods, being M=0.72, the mean of all the values obtained by the different approaches. It has been concluded that in 1952 and 1953 the fishery was already fully exploited, and after several considerations it is claculated that the F level in the fishery of Sardina pilchardus in Galicia (NW Spain) at the present moment may have exceeded the Fmax level.

[ES] La biología de la sardina de las costas de Galicia ha sido ampliamente estudiada especialmente en las décadas de los 50 y 60; sin embargo, dicha información no ha sido utilizada para el cálculo de ciertos parámetros poblacionales, de indudable interés para el estudio de la dinámica de población de esta especie en las costas de Galicia. El objeto del presente trabajo es utilizar la información existente ya publicada para realizar dichos cálculos. [...]
