Mauremys reevesii, commonly known as the Chinese pond turtle, the Chinese three-keeled pond turtle, or Reeves' turtle, is a species of turtle in the familyGeoemydidae, a family which was formerly called Bataguridae. The species is endemic to Asia.
Mauremys reevesii is found in China, Japan, Korea and Taiwan.
Habitat and behaviour
M. reevesii is semiaquatic, and basks in the sun on rocks or logs and can often be found leaving water to do so. They can usually be found in marshes, relatively shallow ponds, streams, and canals with muddy or sandy bottoms.
Any individuals that are available as pets therefore need to be kept separate from other members of the family.
M. reevesii is one of the species raised on China's turtle farms. According to a 1998 survey, 548 farms raised this turtle species in four provinces in China.
The statistical data from different provinces were in different formats; however, two provinces reported 20,650 turtles living on 26 farms, with 5,000 animals reproduced annually; the other two provinces reported the total weight of their turtles, namely some 260 tons of these animals on 522 farms. Over the five-year period, 1990–1995, 13 traditional Chinese medicine factories consumed 430 tons of C. reevesii plastrons.
Based on a more recent (2002) survey of 684 Chinese turtle farms (less than half of all 1,499 turtle farms that were registered at the time), researchers found that 2.8 million of turtles of this species (reported there as Chinemys reevesii) lived on these farms, with some 566,000 specimens sold by farmers every year. The total weight of the annual product was 320 tons, with the estimated value of over US$6 million, which makes the market value of a Chinese pond turtle equal to around $12—about twice as much that of the most common farmed species, Pelodiscus sinensis. Taking into account the registered farms that did not respond to the survey, as well as the unregistered producers, the total amounts must be considerably higher.
Chinese pond turtles are also farmed for the pet trade. In captivity, they require similar care to red-eared sliders (T. s. elegans).
During surveys in East Timor (Timor-Leste), a small but well-established population of M. reevesii was found living in marshes near the city of Dili. The species is not native to the island and was possibly introduced by locals of Chinese origin. East Timor is home to the Roti Island snake-necked turtle of the timorensis subspecies (sometimes considered a species of its own). Although the introduced population of M. reevesii is not known to present a risk to the native turtles per se, they could indirectly present a threat to the natives if confused. M. reevesii from the introduced population are sometimes captured to be sold to people of Chinese origin and this may cause problems if extended to the native turtles. A potential solution is to remove the introduced M. reevesii (thereby restricting the trade to captive farmed M. reevesii).
