Abstract

The grass carp (Ctenopharyngodon idella), a freshwater species native to China, have been introduced in more than 100 countries. In this paper, inter simple sequence repeat (ISSR) markers were used to evaluate genetic variation within and among grass carp populations sampled from its native (China) and colonized habitats (USA, Hungary, and Japan). Twenty-two ISSR primers were used to generate 207 bands, of which 82 (39.61 %) were polymorphic. The highest genetic diversity was observed in the Yangtze River population, whereas the lowest diversity was found in the Tone River population (Japan). Compared with colonized populations, the native populations possess approximately twice as much genetic diversity. The AMOVA analysis showed a relatively high level of genetic variation within populations. Significant genetic differences were revealed both among the native populations and between pooled native and colonized populations.
