Population genetics of wild Siniperca knerii Garman, 1912 in China as evaluated by microsatellites

Population genetics of wild Siniperca knerii Garman, 1912 in China as evaluated by microsatellites The Chinese perch Siniperca knerii Garman, 1912 is an endemic perciform freshwater fish species mainly distributed in the Yangtze River and the Pearl River of China. To evaluate their genetic diversity in these rivers, microsatellite markers were used to assess the genetic structure and genetic variability among nine wild populations of S. knerii. In this study, the 12 loci used were polymorphic, with observed heterozygosity (Ho) ranging from 0.4079 to 0.8886 and polymorphism information content (PIC) ranging from 0.4511 to 0.7146. Results showed that six populations from the Yangtze River had a higher genetic diversity than those from the three Pearl River populations. The Bayesian STRUCTURE analysis recovered genetic clusters that matched localities perfectly or the kind of ecology environment with a significant Fst between them. The findings of this research should provide useful information for management and conservation of S. knerii stocks. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Applied Ichthyology Wiley

Abstract

The Chinese perch Siniperca knerii Garman, 1912 is an endemic perciform freshwater fish species mainly distributed in the Yangtze River and the Pearl River of China. To evaluate their genetic diversity in these rivers, microsatellite markers were used to assess the genetic structure and genetic variability among nine wild populations of S. knerii. In this study, the 12 loci used were polymorphic, with observed heterozygosity (Ho) ranging from 0.4079 to 0.8886 and polymorphism information content (PIC) ranging from 0.4511 to 0.7146. Results showed that six populations from the Yangtze River had a higher genetic diversity than those from the three Pearl River populations. The Bayesian STRUCTURE analysis recovered genetic clusters that matched localities perfectly or the kind of ecology environment with a significant Fst between them. The findings of this research should provide useful information for management and conservation of S. knerii stocks.
