Abstract

  A total of 112 specimens were sampled from Southern Atlantic of Morocco in the period from April to June 2016. Sixty-two dorsal fin spines were analyzed for ageing and growth studies, and all samples (112) were used for biometric studies. The length of the aged individuals ranged from 440 to 704 mm. Fish ages ranged from 1 to 4 years old and the mean length by age were calculated for males and females. The standard von bertallanfy growth function was used to fit length at age data. The growth parameters are L∞= 73.01, K=0.3075 and to=-2.4469. Also, a biometry analysis of Atlantic bonito was conducted in this paper. Relative growth was studied by comparing changes in morphological characters with growth fork length. Length weight relationship is presented as well.
