Field Research


Dr. Peter Pritchard examines one of many Chinese softshell turtles Pelodiscus sinensis observed during interviews in villages along the Red River.
In Search of Rafetus swinhoei
     A survey team led by Dr. Peter Pritchard of the Chelonian Research Institute (USA) headed for Phu Tho Province in November to investigate reports of giant softshell turtles living along the Red River and adjacent wetlands in provinces west and northwest of Hanoi. Dr. Pritchard, TCEP associate biologist Nguyen Quang Truong of IEBR, and Cuc Phuong turtle ecologist Le Thien Duc interviewed fishermen, local traders, and other people living along the Red River.
     Viewing the skeletal remains of a large Rafetus swinhoei softshells, Dr. Pritchard was able to confirm that this species inhabited the Ao Chau wetland in Phu Tho as recently as 15 years ago. Most local reports seemed to turn up the more common Chinese softshell, Pelodiscus sinensis, and restaurants and local traders were able to produce numerous examples of the smaller Pelodiscus.
     Rafetus swinoei is one of Asia’s largest softshell turtle species and is native to southern China, its range probably historically extending southward into northern Vietnam along the Red River drainage. In recent years a single specimen of Rafetus was caught by fishermen in Hoa Binh Province on the Song Da tributary of the Red River. Another specimen is maintained at Hanoi University. However, people are most familiar with a living specimen of Rafetus found in Hoan Kiem Lake, Hanoi.
     The results of the initial Rafetus survey will be reported by Dr. Pritchard, and further field surveys may be carried out to learn more about remnant populations of this species surviving in Vietnam.

Turtle Field Records Needed

     The TCEP has assembled a database of field records for turtles in Vietnam. Please help by forwarding any current records that you believe may be relevant to the TCEP. Valid field records include any observations of turtles in their natural habitat, and records pertaining to turtles observed in the possession/confiscated from hunters within the turtle’s habitat (e.g.,forest). Market and trade records can not be used.
     An accurate description of the turtle will be necessary, along with the date, location, a brief description of the observation, and the name of the observing party. If possible, take a photograph of the turtle in the field.
