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.
