Spatial and Seasonal Variations in the Size-Weight Relationship and Condition Index of the Mangrove Oyster Crassostrea tulipa (Lamarck, 1819) in the Saloum Delta, Senegal

A study on the mangrove oyster Crassostrea tulipa in Senegal's Saloum Delta reveals significant spatial and seasonal variations in its condition index (CI), with values peaking during the hot season and dipping during transitions. The research, spanning 2021–2022, analyzed over 26,790 oysters, finding a minority allometry (b = 2.54) and strong weight-shell height correlation (r = 0.88). These insights are critical for sustainable management of the species, which faces declining wild stocks due to human pressure and mangrove degradation.
