Bivalve biology, gametogenesisAbstract
Very little is known about the reproductive biology of burrowing bivalve species found along the Senegalese coast, despite their cultural and economic importance for the local population. Knowledge of the reproductive cycle of these bivalve mollusks is very important not only for the management of this resource in the natural environment, but also for the development of bivalve mollusk farming. Tagelus adansonii is a bivalve mollusk widely distributed in the mangrove ecosystems of the West African coast. In this study, 360 individuals were sampled from the Joal-Fadiouth lagoon in Senegal over a twelve-month period. Histological sections from these samples showed that T. adansonii is a gonochoric species, with only one case of hermaphroditism detected. The reproduction of T. adansonii in the lagoon was continuous. The maturation and spawning stages were maximal (80%) in July and August, while the early gametogenesis stage was maximal in May. The high gamete emission seems to be favored by lower salinity and higher temperature.
