Reproductive Biology of Uca tangeri (Eydoux, 1835) in the Saloum Delta National Park (Senegal): Sex Ratio, Sexual Maturity, and Fecundity

Research on Uca tangeri, a fiddler crab species, in Senegal's Saloum Delta National Park reveals a male-biased sex ratio (1.21:1) that deviates significantly from parity, with males reaching sexual maturity earlier than females. The study, conducted over 12 months across three stations, also demonstrates seasonal variations in fecundity, peaking during the rainy season. These findings highlight the crab's reproductive dynamics, providing critical insights for conservation efforts and sustainable management of this UNESCO-listed wetland ecosystem.
