First successful captive breeding of Alligator Snapping Turtles (Macroclemys temmincki) in Australia. Thylacinus (1995),20(1),6-9
A total of six neonates have hatched and survived. Two from each of the females incubated at 29-30° C hatched on 7 February, an incubation period of 82 days, and two from "Lacey's" eggs incubated at 25-26° C, hatched on 24 and 26 February and incubation period of 99 and 101 days respectively. After emergence each neonate was checked for remaining umbilical and yolk and returned to the incubator for 24 hours to minimise stress and allow absorbtion of the yolk. After this period they were again checked and if the yolk was still not absorbed they were returned to the incubator. Once the umbilical region was sealed, each neonate was removed and placed on a wet papaer towel substrate and returned to the incubator for a further 24 hour period. The neonates were then removed from the incubators and then weighed, measured and marked, Table 3, using a scute notching system with their studbook numbers. |
Small live fish and shrimp were placed in their enclosures. All of the neonates were feeding daily within 5 to 12 days of their hatch dates. Currently their average daily food consumption is four fish and one shrimp. They are very secretive and no feeding has been observed. Although being handled daily for enclosure cleaning , they appear to be showing no signs of stress and are "happy snappers". Banks, C. and Meikle, W.
