N2  - Samples of the greenback flounder, Rhombosolea tapirina, were collected from five Tasmanian sites and from one site each off Victoria and New Zealand. Thirty enzyme-coding loci were analysed by gel electrophoresis. Seventeen loci were variable, nine of which were polymorphic in at least four samples. Average heterozygosity across all 30 loci was relatively high at 0.086 &#177; 0.032. There were significant genetic differences between the Australian and New Zealand samples, with a genetic distance of 0.041, which was an order of magnitude larger than that observed between any Australian samples. Samples from the west coast of Tasmania and from Victoria were genetically isolated from each other and from the remaining four Tasmanian samples; the latter showed little variation among themselves. Reductions in genetic variation (heterozygosity and alleles) were observed in two cultured cohorts when compared with the wild-caught samples, with corresponding low estimates of effective population sizes compared with putative breeding numbers. No genetic variation was detected between normal and malpigmented individuals from the same culture cohort.
