Abstract   The southern blue whiting Micromesistius australis (Norman, 1937) is found in two geographically distinct areas, the South Atlantic and south-west Pacific Oceans. To date there has been no appraisal of the genetic relationships between the populations in these two areas. Here, we present analyses of New Zealand and Falkland southern blue whiting using mini- and microsatellite loci. Two out of six loci show highly significant allele frequency heterogeneities between the two areas, strongly suggesting genetically distinct populations.

Keywords   Micromesistius australis; minisatellite DNA; microsatellite DNA; New Zealand; Falkland Islands
