Abstract
Three methods were used for age validation 1) Marginal increment analysis (M.I.A.) of 2614 monthly sampled otoliths, 2) Length frequency distribution analysis (LFDA) in a unique sample of 1646 individuals, and 3) Comparison of averaged back calculated lengths at age (B.C.L.A.) from otolith and scale age readings with the mean observed lengths at age in a post stratified sample of 250 specimens.
