Genetic relationships between captive and wild subpopulations of Arapaima gigas (Schinz, in Cuvier, 1822)

Arapaima gigas, also known as pirarucu, is endemic to the Amazon basin. There is currently considerable effort being made to cultivate this species to reduce pressure on natural populations. We characterized the diversity and genetic structure of subpopulations of wild and captive A. gigas based on 19 microsatellite loci. Captive subpopulations of A. gigas exhibited less diversity than wild individuals. We also verified...
