Histological Study of the Sex Ratio and Reproductive Cycle of the Mangrove Oyster Crassostrea tulipa (Lamarck, 1819) in the Saloum Delta (Senegal)

A histological study of the mangrove oyster Crassostrea tulipa in Senegal's Saloum Delta reveals a skewed sex ratio favoring females (1:2.85) and continuous, asynchronous reproduction with peak spawning during warmer months. Researchers analyzed monthly samples of 30 oysters over 13 months using histological techniques, including staining and microscopic examination. The findings suggest that C. tulipa exhibits year-round reproductive activity, with higher frequencies of spawning individuals in the warm season. These insights are critical for informing sustainable management and aquaculture practices for this socioeconomically valuable species in West Africa.
