This is a study of the age and growth of the gastropod Turbo marmoratus using a sclerochronological method. The shells of an introduced population on Tahiti (French Polynesia) are examined. The confirmation of age, based on a novel marking technique using a lead pencil, reveals a daily rate of deposition with the growth rings. A new method of estimation of the growth parameters of the Von Bertalanffy model from the daily ring density (DRD) is described. The fit to the model allows the estimation of K = 0.32/year and D(infinite) = 30.3 cm (D = diameter). (Résumé d'auteur)
