Population genetics of the freshwater fish (Characiformes: Prochilodontidae), using species-specific microsatellite loci.

is a freshwater fish endemic to the Colombian Magdalena-Cauca and Caribbean hydrographic basins. The genetic structure patterns of populations of different members of and the historic restocking of its depleted natural populations suggest that exhibits genetic stocks that coexist and co-migrate throughout the rivers Magdalena, Cauca, Cesar, Sinú and Atrato. To test this hypothesis and explore the levels of genetic diversity and population demography of 725 samples of .
