Polymorphic microsatellite loci for species of Australian freshwater cod, Maccullochella

The Australian freshwater cod genus, Maccullochella is represented by three species: Murray cod, M. peelii peelii, eastern freshwater cod, M. ikei, and trout cod, M.macquariensis. Seven novel microsatellite loci from M. ikei and six previously published loci from M. peelii peelii were tested on wild populations of Murray, eastern and trout cod. Levels of polymorphism varied between species with 13 loci polymorphic in Murray cod, 9 in trout cod and 7 in eastern cod. Observed heterozygosities ranged from 0.053 to 0.842. This suite of microsatellite loci will facilitate future studies of the genetic status of wild and hatchery bred populations of Maccullochella.
