MATING IN THE LAGOON CRAB CARDISOMA ARMATUM HERKLOTS

MATING IN THE LAGOON CRAB CARDISOMA ARMATUM HERKLOTS Cardisoma armatum Herklots, a gecarcinid crab, burrows near brackish water and estuaries (Gauld, 1960). It is a common inhabitant of mangrove swamps along the coast of West Africa. Feeding and migration in the crab have been observed at night. In a review on the mating behavior in the Brachyura (Hartnoll, 1969) the gecarcinids were not covered for an apparent lack of information in the literature. Since this review, there has not been a full description of mating for any member of the family (Fotheringham and Brunenmeister, 1975; Henning, 1975a, b).

Abstract

Cardisoma armatum Herklots, a gecarcinid crab, burrows near brackish water and estuaries (Gauld, 1960). It is a common inhabitant of mangrove swamps along the coast of West Africa. Feeding and migration in the crab have been observed at night. In a review on the mating behavior in the Brachyura (Hartnoll, 1969) the gecarcinids were not covered for an apparent lack of information in the literature. Since this review, there has not been a full description of mating for any member of the family (Fotheringham and Brunenmeister, 1975; Henning, 1975a, b). This paper provides information on the mating behavior in a gecarcinid and relates mating to the molt stage of the female. MATERIALS AND METHODS Crabs used in the work were trapped at Dzita, a fishing village approximately 200 km to the east of Accra, Ghana. They were maintained in large aquarium tanks (50 1) which were filled with soil into which the crabs burrowed. In the laboratory, the crabs were fed palm nuts, banana, coconut pulp, cassava, Paspallum, Sesuvium, and dead leaves of Avicennia, and were provided with water. In the experiment, ten individuals of either sex measuring between 60 and 80 mm in cephalothorax width (CW) were
