Etude de l'esturgeon Acipenser sturio dans le milieu naturel : mise au point d'une méthode d'estimation de l'âge individuel de l'esturgeon européen (A. sturio)

Abstract : The goals of this study are to design a method of in-vivo measurement of a section of pectoral radius, to define the usable tools, the feasibility and methods of this operation, to determine the most efficient methods among five section observation methods and the possible reading differences among these methods, to define, based on histological observations made on the radius section, criteria to estimate the fish age, and to suggest validation methods.
