摘要: Three mitochondrial DNA sequences (COI, ATP 8 & 6, and D-loop) were employed to assess the genetic diversity of four populations of silver carp from three main drainages in China, including the Yangtze River, the Amur River, and the Pearl River. As a result, 98 haplotypes were identified in combined sequences of COI, ATP8 & 6, and D-loop. A total of 196 variable sites and 116 parsimony-informative sites were observed. AMOVA based on assembled sequences indicated that 12.12% of the variation was among populations, while 87.88% of the variation was within populations. Additionally, the phylogenetic relationships of populations were depicted in a phylogenetic tree based on assembled sequences. Mismatch distribution analysis and the negative significant Fu's F-s values supported population expansion in all populations. Despite the high level of genetic diversity, the establishment of a state-level original breeding farm in the Amur River basin and the Pearl River basin may be an effective conservation strategy for the protection of local unique haplotypes.
