Panulirus ornatus is a highly-valued tropical spiny lobster species with an extensive Indo- West Pacific distribution, ranging from the east coast of Africa through to the central Pacific Islands. The species is intensively fished throughout its range to supply a rapidly growing Asian seafood market, where colourful large lobsters are highly prized as a luxury seafood. Post-larval and juvenile lobsters are also intensively harvested as seed to supply a burgeoning lobster aquaculture industry that began in Vietnam and is quickly spreading, especially in Southeast Asia. With intense fishing pressure on wild stocks of P. ornatus, and the prospect of new technology for hatchery-raising this species, there is a need to better understand the genetic structure of the global population of this species to improve management prospects. Therefore, this study aimed to use molecular genetic techniques to determine the population structure, connectivity and patterns of seascape genetics in P. ornatus throughout its global range. A total of 298 specimens were sampled from 17 locations covering the West Indian Ocean, Western Australia, Southeast Asia, and the Northwest and Southwest Pacific. From sequencing a 461 bp fragment of mitochondrial control region from these samples, high levels of haplotype diversity (H=0.99) and overall significant population differentiation (Φst = 0.113, P
