Chinese pond turtle
|Chinese pond turtle|
The Chinese pond turtle, Reeves' turtle, or Chinese three-keeled pond turtle (Mauremys reevesii) is a species of turtles in the family Geoemydidae (formerly called Bataguridae). It is found in China, Japan, Korea and Taiwan. This species 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.
The Chinese three-keeled pond turtle (M. reevesii) is threatened by competition with released pet red-eared sliders (T. s. elegans), overhunting (its plastron is used in traditional Chinese medicine), capturing for the pet trade and wild habitat destruction. The IUCN considers M. reevesii an endangered species. This species, fortunately, breeds well in captivity.
This species is notorious for its ability to produce hybrids with other Geoemydidae, even species that are only distantly related. The supposed new species "Mauremys" pritchardi was based on a hybrid of unknown origin between a male of this species and a female yellow pond turtle (Mauremys mutica). Furthermore, it has hybridized with the Chinese stripe-necked turtle (Ocadia sinensis), female Malayan box turtles (Cuora amboinensis), a male four-eyed turtle (Sacalia quadriocellata), and the Japanese pond turtle (Mauremys japonica) in captivity.
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).
M. reevesii was not known to be present in Timor-Leste until during a conservation survey for other reptiles researchers confirmed its presence. M. reevesii is used in traditional Chinese medicine and kept as pets in Timor-Leste. The turtles are sold on the street in the more affluent districts of the capital. In order to ensure the viability of the population of M. reevesii in Timor-Leste researchers in uniforms informed individuals buying the turtles of their endangered species status to persuade the purchasers to donate the turtles for conservation efforts. Buyers of M. reevesii were not purchasing the turtles for food or medicine but were purchasing them as either pets or to release them for good luck (in relation to the Chinese New Year in this instance) and after convincing by the researchers would give the turtles to the researchers. In Timor-Leste the researchers found that volunteers in official clothing talking to people about the over exploited species is the best way to conserve the species.
