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...
