Abstract
Six samples (n =67 to 154) of blue-eye or deepsea trevalla were collected from south-eastern Australia
(seamounts off New South Wales, a seamount south-east of Tasmania called the Cascade Plateau,
off the east, south and west coasts of Tasmania, and off the coast of South Australia). All fish were
analysed by starch or cellulose acetate electrophoresis for the products of seven polymorphic loci (defined
in this study as those with an average heterozygosity greater than 0.06); a minimum of 24 fish per area were
also analysed for 29 other less variable loci. The average heterozygosity per locus was 5.3%.
Polymorphic loci showed no significant deviations from Hardy-Weinberg equilibrium. The coefficient
of genetic subpopulation differentiation, GST, was 0.38%. Bootstrapping procedures showed that this
low value could be attributed to sampling error alone. Contingency Χ2 analysis similarly failed to reveal
any significant inter-sample differentiation for any locus. The results indicate that gene flow is sufficient
to prevent any genetic differentiation among the sampled localities. During the course of the study a second
trevalla species, Schedophilus labyrinthicus, was identified in the New South Wales component of the fishery.
