| Abstract |
|
Chelodina oblonga logicollis Emydura Pseudemydura Elseya Geochelone Testudinidae radiata Ultra-sound scanning was used to identify, count, and measure ovarian follicles, preovulatory follicles, ova at the beginning of the oviductal period, and oviductal eggs at different stages of shell deposition in live turtles, Chelodina oblonga. An accuracy of >92% was found when counts of the largest size class of follicles and, after ovulation, subsequent counts of oviductal eggs were compared with the number of eggs actually laid by individual animals. The technique permits measurement of the diameter of all size classes of follicles which enlarge in groups as well as the length and width of eggs in the oviducts. This simple, nondestructive method to assess reproductive state is equally applicable to other species of turtles and should greatly enhance knowledge of reproductive patterns.
