At the end of the incubation period the eggs are put in sand 

 tanks from which the baby turtles reach the surface as in a 

 natural nest. 



Problems 



To arrange constant temperature in all parts of the room, 

 the pipe system has to be carefully designed. Therefore, we 

 installed thermometers in seven specific points in the room, 

 readable from outside. To run the hatchery without technical 

 problems non-electronic equipmentmust be chosen. The biggest 

 problem may be the humidity inside the room and the collector 

 (humidity is high in French Guiana — up to 95%) . So both must be 

 dried out and all nests kept inside isolating boxes. Boxes have 

 the advantages of keeping a steady temperature and humidity for 

 every nest separately and makes moving easy. 



Philosophy 



To build a hatchery allowing to "the making" of males or 

 females as we wish would be perfect. But how many females or how 

 many males should we produce? 



Should we copy natural sex-ratio? Should we produce 50% of 

 each sex? Should we increase the number of females, that 

 experience a high mortality rate and are responsible for the 

 species reproduction? Who can say?
