Between 1984 and 1990, a total of 4892 bogues, Boops boops (L.) were caught in Peniche and 4352 in Algarve, with the total length varying from 6 to 40 cm. Age determination was carried out using direct reading and back‐calculation on the otoliths. Von Bertalanffy growth equations, based on mean lengths per age group, were established for both samples and using both methods. Applying the Hotelling T 2 test to the growth parameters of those equations, it was concluded that there were no significant differences between them. This conclusion allowed the validation of the two methods employed, and the combination of the data from Peniche and Algarve into one single age‐length key from which a growth equation for the Portuguese coast was calculated and described as: L t = 45.918 {1‐exp [‐0.124 ( t + 2.628)]}.
