First approach to the growth and age corroboration of Northeast Atlantic chub mackerel (Scomber colias) in northern Iberian Waters
The growth pattern and parameters of Atlantic chub mackerel in Northern Iberian waters were analysed for the first time in this study, using otolith analyses (direct age estimation-DAE, back-calculation-BC and otolith marginal analyses) and length frequency analyses (Bhattacharya, SLCA and PROJMAT m...
