Isolation and characterization of 24 microsatellite loci for the commercial Amazonian freshwater catfish Brachyplatystoma capapretum (Siluriformes: Pimelodidae)

Twenty-four microsatellite loci were characterized for the Pimelodidae Brachyplatystoma capapretum and tested on 26–38 individuals from the Amazon basin. The number of alleles per locus ranged from 1 to 12 with the observed and expected heterozygosity values varying from 0.02 to 0.93 and 0.08 to 0.81, respectively. Twenty-one of the loci were in Hardy–Weinberg equilibrium, and twenty-two were successfully cross-amplified in at least two Brachyplatystoma species. These loci will be usefully to measure the genetic diversity status on B. capapretum specie as in Brachyplatystoma genus.
