Octopus exhibits a large individual variability in growth and the exponential growth curve is the best fitting theoretical model among other usual models tested. Globally, the growth rates were comparable in the sea and in tanks. Growth rates for the hot season were lower than those for the cold season. Applied to in situ data, the statistical tests showed that females grow more quickly than males. Life expectancy was estimated at between 12 and 14 months. These results question the previous growth curves for the region, all of which were obtained from modal analysis using size or weight-frequencies and were used during stock assessments of this important resource off the north-west African coast. specialized PECHE DE MOLLUSQUES ESPECE COMMERCIALE ESTIMATION DE STOCK CROISSANCE MARQUAGE MALE FEMELLE ESPERANCE DE VIE DYNAMIQUE DE POPULATION MODELISATION VARIATION SAISONNIERE SENEGAL 040PECHE03 80 699-705 2000 0025-3154 https://www.documentation.ird.fr/hor/fdi:010030056 10.1017/S0025315400002526 0025-3154 [F B010030056] https://www.documentation.ird.fr/hor/fdi:010030056 https://www.documentation.ird.fr/intranet/publi/2025-08/010030056.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2003-03-24 2025-08-18 fdi:010030056 fre
