The age was determined by interpreting and counting daily increments on the otoliths sagitta of 320 individuals sampled from landings caught by different gears specially by purse seine. The parameters of the Von Bertalanffy growth curve were estimated for sexes combined: L-f = 31.46(1 - e(-0.228) ((t+3.034))) (L-infinity = 31.46 cm, k = 0.228 per year, t(o) = -3.034 years); for male L-f = 27.43(1 - e (-0.422) ((t+1.747))) (L-infinity = 27.43 cm, k = 0.422 per year, t(o) = -1.747 years) and for female L-f = 31.70(1 - e(-0.227) ((t+2.196))) (L-infinity = 31.70 cm, k = 0.227 per year, t(o) = 22.916 years) for the whole study period. The difference between the growth of male and female is not significant. The relationship between length and weight shows a length growth faster than of the weight with parameters of the equation W-t = a*L-b; a = 9.89*10(-5) and b = 2.37 for the sexes combined. specialized age growth mackerel Tunisia Scomber scombrus microstructure TUNISIE 034 93 2 351-355 2013 0025-3154 https://www.documentation.ird.fr/hor/fdi:010060697 10.1017/s0025315412000501 0025-3154 [F B010060697] https://www.documentation.ird.fr/hor/fdi:010060697 https://www.documentation.ird.fr/intranet/publi/2013/03/010060697.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2013-04-02 2017-08-23 fdi:010060697 fre
