Reproductive characteristics of Tokay gecko (Gekko gecko Linnaeus, 1758) in captivity

Abstract

Captive farming of the Tokay gecko has recently begun in some provinces in Vietnam. However, the supporting knowledge on species' biology, ecology, behavior, reproduction and husbandry techniques is limited. In this study, the captive geckos were monitored from 2011 to 2012. The study results show clear signs for distinguishing the sex of the geckos. The male has two rows of holes along the thigh forming a V shape and two dark dots under the anus. The female’s markings are uncertain. The breeding season begins in March when their environment begins to warm. Gecko reproduction reaches its peak during the period from May to August. The reproductive season ends in October as their environment cools again. Geckos usually lay 2 eggs per batch, but may sometimes lay 1 or 3 eggs. The incubation period is about 90 - 100 days. Gecko eggs can hatch in normal environmental conditions. Captive geckos should be provided with adequate food, bamboo and wooden boxes for the highest reproductive success.
