Chilling the Eggs During Incubation
as the Key to Successful Breeding of the
Annam Leaf Turtle Mauremys annamensis (SIEBENROCK, 1903)
- by H. ARTNER -
A breeding report of a group of two males and three females of the Annam Leaf Turtle Mauremys annamensis over
a period of several years is given. Notes on the systematic status of the genus Mauremys are provided followed by a detailed
description of the captive maintenance conditions. The turtles are almost exclusively fed on an artificially colored feeding gel containing fish, meat, carrots, chicken liver, shrimps, and additional vitamins and calcium. The author had better breeding results
when the sexes were kept separately all year except for mating attempts when one male and one female were put together in small
aquaria under constant observation. A seasonal rhythm like in the distribution area in central Vietnam was offered. Hibernation
took place at 8–12 °C for 3 months. Mating occurs in spring, when the female is placed into the male’s tank.
Keeping and Breeding
the Big-Headed Turtle
Platysternon megacephalum megacephalum,
with Remarks on Subspecies Validity
- by J. GAD -
Keeping and breeding of the big-headed turtle Platysternon megacephalum megacephalum are described. A synopsis
of literature is given, and the author’s own observations are presented. 1.2 specimens were kept for over ten years.
Captive Breeding of
McCord’s Box Turtle
Cuora mccordi ERNST, 1988
- by H. Artner -
Cuora mccordi was described as recently as 1988 on the basis of market/pet trade specimens. There are as yet no reports of the natural occurrence of this species. It may well be that it has already become extinct in its East Asian habitat. The life history of the species is therefore virtually unknown.
Keeping and Breeding the
Yellow-headed Sideneck
Podocnemis cayennensis
(SCHWEIGGER, 1812) over years
- by Harald Artner -
Keeping and breeding of the Yellow-headed Sideneck or Terecay Podocnemis cayennensis in captivity are described in detail. Own observations and data are compared with other published data. Comments on its distribution, natural history and nomenclatural problems are also given. Until 2000 two adult pairs of the species were kept. Since then only one pair remained. The remaining female has successfully reproduced in 1997, 2001, 2002, and in 2005. All together, 53 hatchlings were produced. They had carapace lengths of appr. 40 mm and weighed 10 g.
