Age and growth studies of hake (Merluccius merluccius L.) from ICES Divisions VIIIc and IXa

The present work is done on 801 hake otoliths originating from Divisions VIIIc and IXa. Preliminary results concerning the existence of false rings anterior to the first Winter ring are found. This is the way that they are defined: larval zone, pelagic ring, recruitment ring and summer ring (table 1...
