Description
Summary:National audience A technique to determine the sex of the Atlantic salmon (Salmo salar ) from external features is proposed. A total of 214 individuals caught in July and August 1986 in five rivers in Quebec and at a salt water location have been studied. Overall, the sexual dimorphism of the relative length of the upper jaw bone allowed us to sex the fishes with 88% success. Une technique d'identification externe du sexe chez le Saumon atlantique (Salmo salar) est proposée. Deux cent quatorze individus capturés en juillet et août 1986 dans cinq rivières québécoises et à un site en eau salée ont été étudiés. Pour l'ensemble de l'échantillon, le dimorphisme sexuel de la longueur relative de la mâchoire supérieure a permis une identification exacte du sexe dans 88% des cas.
