Variaciones en el stock de sardina (Sardina pilchardus Walb.) de las costas atlánticas de la Península Ibérica (1976-1985)

In the period 1976 to 1985, the sardine stock of this region has undergone oscillations in abundance, mainly due to variations in recruitment. A hypothesis of migration is proposed, based on the similarity in age class distribution revealed both by the captures and by acoustics. Both techniques show a similar pattern of differential age class distribution.

En el período 1976-1985 el stock de sardina en esta área ha estado sometido a una tasa de explotación bastante estable. Las oscilaciones de la abundancia se han debido a las variaciones del reclutamiento y no se ha encontrado una relación entre éste y el afloramiento.
