Relocate nests/eggs for artificial incubation: Crocodilians
A study in 2009 in two river basins in Venezuela (Barros et al. 2010) found that most American crocodile Crocodylus acutus and Orinoco crocodile Crocodylus intermedius eggs hatched successfully after being collected from the wild and artificially incubated. Results were not statistically tested. In total 66% of American crocodile eggs (200 of 305 eggs) and 54% of Orinoco crocodile eggs (116 of 216 eggs) hatched successfully after artificial incubation. Egg collection was carried out in 2009 (521 eggs collected overall) in the Santa Ana (305 American crocodile eggs) and Manapire (216 Orinoco crocodile eggs) river basins. Eggs were transported to a brick-walled building in each location (25 m2 and 5 m2 in size) with a zinc roof closed to predator access. The larger incubation room temperature was maintained at 32ᵒC by five light bulbs. Eggs were stored in sand-filled insulated polystyrene boxes. The sand was kept damp by adding water at regular intervals.
