Isolation and development microsatellite markers in the Pygocentrus nattereri (Kner, 1858) (Characiformes, Serrasalminae), an important freshwater fish in the Amazon
The red-bellied piranha belongs to the Pygocentrus genus, and is a representative of the Serrasalmidae family. The P. nattereri is the most abundant species in the floodplain of the Solimões-Amazonas river system. In the present work, 11 microsatellite loci were developed and used to investigate the...
