Abstract: In order to understand the germplasm resources and genetic diversity of wild freshwater fish in Beijiang River of Guangdong Province; an investigation was made in 2007-2008. Thirty-two species of wild freshwater fish were collected; belonging to three orders; ten families; and twenty-seven genera; among which; there were twenty-one species of Cypriniformes; four species of Perciformes; and seven species of Siluriformes. Of the twenty-one species of Cypriniformes; there were twelve species belonging to Cobitidae; Homalopteridae; Gastromyzonidae; and Balitoridae. The mtDNA D-loop sequences of test freshwater fish were determined; and submitted to GenBank (Accession numbers EU380208-EU380236 and EU697088-EU697148). Molecular phylogenetic trees were constructed by using the maximum parsimony method. All the results showed that Beijiang River had abundant freshwater fish resource; and mtDNA D-loop could be a good molecular marker for the fish species identification.
