Abstract
Eight primer sets that amplify microsatellite DNA loci were developed for the estuarine fishes, dusky flathead Platycephalus fuscus and sand whiting Sillago ciliata , which are targets of recreational and commercial fishers on the east coast of Australia. Surveys across these loci revealed remarkably similar levels of genetic diversity within samples of c . 22 P. fuscus and S. ciliata from each of the two estuaries. These loci will be useful in determining the genetic stock structure of these two species.
