Abstract Background: Piracanjuba (Brycon orbignyanus) is a fish species highly affected by anthropogenic actions such as overfishing, water pollution, and hydroelectric developments. This species is currently considered in danger of extinction. Objective: To analyze the genetic diversity of a natural population (NP) and two captive broodstocks (SA and SB) of B. orbignyanus. Methods: Samples of caudal fins (NP: 24, SA: 30, and SB: 30) were collected. DNA was extracted and amplified for six RAPD primers and four microsatellite loci. Results: Sixty polymorphic fragments and 17 microsatellite alleles were detected. High intrapopulation heterozygosity (NP: 0.692, SA: 0.724, and SB: 0.686) was observed. Thirty-eight fragments and six alle...
