Isolation of microsatellite DNA and analysis on genetic diversity of endangered fish,Hucho taimen (Pallas)

Hucho taimen (Pallas) is an endangered species in China. To evaluate the species’ genetic diversity and population genetic structure, we isolated six polymorphic microsatellite markers from its genomic libraries by (ACA)₁₆ enriched, and characterized using 61 wild individuals. The number of alleles per locus ranged from two to seven, expected heterozygosity ranged from 0.3200 to 0.7410, polymorphism information content ranged from 0.3047 to 0.6896. These markers will be useful for the genetic variation assessment of taimen.
