| Abstract |
The sandbar shark, Carcharhinus plumbeus, is landed in fishing sites located along the coast of Senegal (Eastern tropical Atlantic). The smallest mature male was 165 cm in total length (TL) and weighed 14 kg while the largest male reached 193.5 cm TL and weighed 32 kg. The smallest adult female was 179 cm TL and weighed 25 kg while the largest female was 225 cm TL and weighed 64 kg. Parturition occurred from April to June. The gestation period was estimated at twelve months, at most. Females appeared to reproduce every two years. Size and mass at birth were based on near-term embryos and neonates; it probably occurred between 58 and 65 cm TL (mean: 60.3 cm ± 1.55) and between 0.92 and 1.52 kg (mean: 1.08 kg ± 0.133). Litter sizes ranged from 4 to 12. Embryos and post-partum males did not significantly outnumber the females. |
