A population genetics study of the commercially important Green Tiger Prawn (Penaeus semisulcatus) was conducted in the Indo-Pacific Ocean with a focus on the Indo-Malay Archipelago waters of the South China Sea, Sulu Sea, Celebes Sea and the Strait of Malacca. The aim of this study was to identify the potential location of this genetic break in the Indo- Pacific Ocean, based on the mitochondrial cytochrome c oxidase I (COI) and control region (CR) genes, on a narrower geographical scale in the Indo-Malay Archipelago waters. All populations were differentiated into two lineages with a genetic break in the vicinity of Bagan Pasir; Lineage I comprised populations from the Pacific Ocean-South China Sea, Sulu Sea and Celebes Sea, while Lineage II was composed of northern to central populations in the Strait of Malacca. The Bagan Pasir population is considered a mixture of gene pools of the two lineages, and probably represents the area (or vicinity) of demarcation of the two lineages. Understanding population genetic diversity and structure is vital for managing productive fisheries, conserving genetic resources and sustainably harvesting populations of of marine organisms.
