Abstract: The different stages in the development of the mangrove clam Anodontia edentula from fertilization up to metamorphosis was described in terms of timing, immediate morphology, and growth including the rearing conditions that lead to the successful completion of cultures. Anodontia edentula exhibited the typical bivalve life cycle starting with the trocophore larvae which further developed into the veliger and pediveliger stages before undergoing metamorphosis to form spats. It was established that the larval rearing of this species in the lab is difficult. Most trial cultures stayed for about 5-7 days reaching only the veliger stage. After employing relevant strategies, the cultures were stretched up to 22 days until metamorphosis. This study was able to update literature on the early life history of A. edentula. It explored effective management of bivalve larvae cultures for experimental purposes. This study also has direct implications in bivalve aquaculture and restoration Biology. To be able to artificially propagate this species both for food and for the conservation and rehabilitation of mangrove stands, knowledge of its developmental stages as well as the conditions for efficient survival is imperative.
