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 (SCS), Sulu Sea (SLS),
Celebes Sea (CLS) and the Strait of Malacca (SOM), the latter being the
main waterway that connects the Indian Ocean with the Pacific Ocean. A
548-base-pair region of mitochondrial COI
and 571 base pairs of the control region (CR) were analysed in 284
specimens from 15 locations. Genetic divergences (Tamura 3-parameter)
for COI ranged from 0.1% to 7.2% and CR 2.3% to 21.7%, with Bagan Pasir
(BGP) in central SOM being the most genetically different from other
populations (COI: 3.3–4.2%;
CR: 7.1–16.5%). All populations were differentiated into two lineages
with a genetic break in the vicinity of BGP; Lineage I comprised
populations south of this site (SCS, SLS, CLS and part of SOM) and
Lineage II comprised populations north of BGP (part of the SOM).
Specifically, most individuals of Bagan Pasir (BGP) and another site
just south of it, Batu Pahat (BPT), clustered in Lineage I, while all
SOM populations to the north of these sites clustered in Lineage II.
The BGP population is believed
