6392 specimen of sardines were sampled during the period 1980-1984. The spawning season was ca1culated from the monthly percentages of mature individuals, gonadosomatic index, condition factor and viscera1 fat. The size and age at first maturation and the size/weight ratio were calculated.Pendant la periode 1980-1984 des echantillonages biologiques regulieres sur la sardine ont ete realises et 6932 exemplaires ont été examinées. On determine la saison de ponte a partir de l'evolution mensuelle du pourcentage des individus mûrs et de la variation du l'indice gonadosomatique, le facteur de condition et la graisse viscerale. On calcule aussi la taille et l'age de premiere maturation et les equations taille/poid vive et poid eviscere
