Patterns of genetic diversity of mitochondrial DNA within captive populations of the endangered itasenpara bitterling: implications for a reintroduction program

In this study, the level of genetic diversity of captive populations of the itasenpara bitterling ( Acheilognathus longipinnis ) was assessed to obtain information useful for successful captive breeding and reintroduction; this analysis was performed using mitochondrial DNA (mtDNA) sequence data.

Description
Summary:In this study, the level of genetic diversity of captive populations of the itasenpara bitterling ( Acheilognathus longipinnis ) was assessed to obtain information useful for successful captive breeding and reintroduction; this analysis was performed using mitochondrial DNA (mtDNA) sequence data. Comparison of the captive and wild populations showed low levels of genetic diversity within the captive population and significant genetic differentiation among the captive populations and also between the wild and captive populations, suggesting at chance effect during the founding process for the captive population and a subsequent genetic drift. Therefore, for successful reintroduction, it is important that the reintroduced population reflects all the genetic diversity available from the captive populations, and that releasing a large number of individuals that consist of all captive populations.
