Females in farms are said to mature at about 28 cm carapace length and 2.5 kg size at the age of five years, and produce clutches of 15–20 eggs (ATCN unpublished report 2004). No corresponding data from the wild appear available. Generation length is estimated at about 15 to 20 years, with old animals estimated to be about 40 to 50 years. Zhou and Li (2013) report age at maturity for females is 3–6 years, and 2–4 years for males in captivity.
Palea steindachneri occurs in southern China (Guangdong, Guizhou, Yunnan and Hainan), and in east-draining river systems of northern and central Viet Nam and adjacent Lao PDR. Introduced subpopulations are known from Mauritius, Hong Kong (China) and Hawaii (USA).
Palea steindachneri has been listed on CITES Appendix II since 2013. It was declared a National Protected Wild Animal Category II in China’s Wild Animals Protection Law. It is not specifically protected under Vietnamese legislation, although the Forest Protection Law should offer a modicum of habitat protection. The species likely survives within suitable habitat in protected areas in Viet Nam.
The primary conservation measure needed for P. steindachneri (and many other species and their ecosystem) is the creation of secure, adequately managed protected areas with suitable habitat. Surveys to evaluate the status and occurrence of populations can be integrated into broader biodiversity surveys. Research on natural history and ecology, and evaluation of genetic and morphological variability, are desirable.
