Abstract: Objective To investigate the species composition and geographic distribution of fresh-water crabs in Fujian province, China, and to provide technical guidance for the prevention and control of related diseases.Methods Specimens collected in Fujian province were systematically classified and preserved. A database was constructed with descriptive information, images, and related data. Results A total of 710 specimens in accordance with biological criteria were collected with complete records. All specimens were classified into 2 families, 5 genera, and 13 species. Among these were Somanniathelphusa zhangpuensis of the genus Somanniathelphusa, Nanhaipotamon nanrienseof the genus Nanhaipotamon,Huananpotamon angulatum, H. changpodum, and H. sheniof the genusHuananpotamon, Sinopotamon fjkienense, S. jianglense,S. chekiangense mindongense, S. pinheense, and S. zhangzhouense of the genus Sinopotamon, and Bottapotamon fukienense,B. yonganense, and B. engelhardtiof the genusBottapotamon.Conclusion A database containing the information on population classification and geographic distribution of fresh-water crabs in Fujian province and a resource sharing platform for permanent preservation of fresh-water crab specimens have been established.
