First data on sexual maturation and sex-ratio of hake (Merluccius merluccius L. ) from ICES Divisions VIIIc and IXa

Tbis paper presents the first data about the length of first maturation (L 50%) of the hake in waters of the Spanish Atlantic Shelf (Divisions VIIIe and IXa). The values obtained were of about 39 cm. for males and of 56 cm. for females. We also point out preliminary results about the time of spawnin...

The values obtained were of about 39 cm. for males and of 56 cm. for females. We also point out preliminary results about the time of spawning, January to May for females and October to May for males. The percentage of both sexes for this species during an annual cycle is also presented. Ce travail aborde unes premiéres données sur la taille de premiére maduration (L 50%) du merlu du plateau Atlantique Espagnole (Division VIIIe et IXa). Les resultats sont, a peu prés, de 39 cms pour les males et 56 cms pour les femelles. On présentent aussi, les résultats preliminaires sur l'epoque du ponte, qui comprendre la période Janvier-Mai pour les femelles et Octobre-Mai pour les mals. Nous donnent, aussi, le poureentage par sexes trouve pour cette espéce pendant un cycle annuel.
