|
Rotterdam Zoo has had pig-nosed turtles in its animal collection since the large exhibition NOTOGAEA (on Notogaean flora and fauna) in 1978, and added several specimens since. Over the years the animals have been kept in two different enclosures, and in several combinations, due to size differences, availability of space and aggressive behaviour. In 2004 three of the animals were kept together in a 15.000 l aqua-terrarium, in the company of other large fresh water turtles and fishes. The animals were separated again as one of them, later determined to be a male, had damaged one of the others, as occurred in the years before on numerous occasions. In January 2005 one of the remaining turtles, obviously a female, was found to have left the exhibit during the night, and to have produced three eggs of which two were broken. She had done this in the public are of the building where the aqua-terrarium is situated, the Riviera hall. After the female had been placed in an off-exhibit enclosure, she produced another 21 eggs after injection of Calcium-Sandoz and Oxytocine. Of these eggs, 15 successfully hatched, after 84-112 days, and most after submersion in water. This is believed to be the fourth captive breeding ever, and the first one that documents the complete reproduction process in captivity. A second female laid 5 eggs in the water two weeks later; one egg could be saved and proved to be fertile as well. This egg also successfully hatched. Details are given on housing, nutrition, egg laying and hatch and rearing of hatchlings. A short video of under water hatching will be shown.
