| Abstract | This study evaluated levels of genetic diversity of L. chrysophekadion, one of the important migratory cyprinid speciesin the Mekong River using inter-simple sequence repeat (ISSR) markers. Fish samples were collected from four populationscomprising three populations in the Mekong Delta of Viet Nam (An Giang, Can Tho and Dong Thap provinces) and onepopulation in Lao PDR. Seven ISSR primers were selected to analyze 90 individuals (19-24 individuals/ population), yielding275 bands (sizes from 400 bp to 2,900 bp). Results showed that four populations of L. chrysophekadion had high levels ofgenetic diversity with the percentage of polymorphic loci from 81.785.9%, expected heterozygosity 0.2760.306, number ofeffective alleles 1.471.54, and Shannon index 0.4150.451. Four populations in Laos and Viet Nam had low geneticdifferentiation (Nei's genetic distance range: 0.016 0.022), suggesting a long migratory distance, approximately 1,200 km, ofthis species. |
