Resumen
The variation in moisture and temperature was analized in the hatching of olive ridley turtle Lepidochelys olivacea eggs, during the 1992-1993 season in �El Verde� beach (Sinaloa, Mexico). This variation was compared for different incubation environments (natural nests, corrals and polystyrene boxes). The results show that the average temperature was 33.6°C in natural nests, 32.8°C in corral and 32.1°C in boxes. Moisture percentage fell between 59.6% to 23.4% as calculated by the weight method and for saturation of 22.9 mL g-1 to 8.8 mL g-1. Hatching percentage was 67.9% in natural nests, 64.1% in corral and 46.9% in boxes. A granulometric study of sand showed differences in sand grain for nests areas. For this season the incubation average temperature was 32.7°C; for this reason, the hatchlings were females. The moisture levels registered in each incubation environment in this experiment apparently were not a determinant factor for the hatching success.
