- •
Otolith microstructure has been analyzed through sagittal and transversal sections of black hake otoliths.
- •
From juvenile and adult black hake otoliths, daily increments have been counted and measured from birth to death.
- •
Black hakes are fast growing species, reaching 36.7 cm in the first year.
- •
Different growth strategies are here supported, even though results point to similar growth models.
- •
Otolith microstructure analysis may be a realistic choice to regularly age hakes.
