|Abstract:||Ageing of redfish is one of the major problems within the research related with redfish. In this paper it is
validated the age readings of S. mentella in Flemish Cap following the most important year-classes along the last 13
years. The criteria used for S. mentella looks consistent and coherent.
Growth of different S. mentella cohorts is described and compared observing the existence of a remarkably
density-dependence growth in the strong 1990 year-class, which performed a slowest growth rate. This reduction in
growth rate has prevented that this cohort become mature at expected age.
Then growth was compared between sexes both in S. mentella, S. marinus and S. fasciatus showing that
females grow faster than males. Finally the growth rate is compared among species. S. marinus displayed the fastest
growth and S. mentella the lowest, although the mentioned density-dependence in S. mentella has to be considered
in the comparison.|
