Deskripsi

The restocking programs are being used more frequently as methods of fish conservation. However, the reduction in the genetic diversity can affect survival of juveniles used in this programs and cause effects on the wild populations. The aim of this study was assess the genetic diversity in three broodstocks (BA, BB and BC) of pacu Piaractus mesopotamicus of a Hydropower plant in São Paulo - Brazil, using in restocking program of Tietê River. Nine RAPD primers were amplified used extracted DNA from 89 fin-clipping samples. Sixty-nine fragments were polymorphic, 15 had frequencies with significant differences (P
