| Abstract: | Channa argus is one of the most important economic fish species in China. However, there is limited genetic information on its population structure and genetic diversity. Nineteen novel polymorphic microsatellite loci were isolated and characterized in 42 individuals from one natural population collected from the Poyang Lake in Jiangxi Province. The number of alleles per locus ranged from 5 to 18 with an average of 11.16. The observed and expected heterozygosities ranged from 0.214 to 1.000 and from 0.630 to 0.923, respectively. The average polymorphic information content value was 0.814. Among these polymorphic microsatellites, eleven loci conformed to Hardy–Weinberg equilibrium. These microsatellite loci are currently being used to assess the genetic diversity and population structure of C. argus and will contribute to the effective conservation and rational utilization of genetic resources of this species. |
