Abstract
    We present evidence that incubation of brine shrimp Artemia encysted embryos (cysts) at high temperatures (36-37°C) suppresses hatching of cysts from a parthenogenetic population, while at the same time allowing cysts of the New World bisexual species (A. fransiscana) to hatch. This approach is used to verify the presence of contaminating foreign material from the New World in natural cyst populations of Old World A. parthenogenetica, A. sinica, A. urmiana and A. tunisiana. We demonstrate that high temperature incubation can be routinely applied to cysts from natural Artemia populations occurring adjacent to fish and shrimp hatcheries, to determine the extent and source of contamination.
