| Summary: | This study investigated genetic diversity of the giant tiger shrimp (Penaeus
monodon), an economically important penaeid species in Indonesia, using 558
base pairs of the mitochondrial cytochrome c oxidase Subunit I (COI) gene. A
total of 10 samples were collected from three populations throughout
Indonesia and three samples were taken from hatchery. The mitochondrial COI
results found high levels of genetic differentiation. From Bayesian tree
building method there were two clades on phylogenetic tree with high
posterior probability value 1.00. COI mt-DNA analyses revealed that there
were six haplotypes in which four haplotypes in clade A and two haplotypes
in clade B. Divergences of COI between two clades showed an average 6.9%
(range=6.7%-7.6%), while genetic distance within clade A 0.2% (range=0-0.5%)
and within clade B 0.3% (range=0-1.1%). Results from this study suggest the
occurrence of two cryptic species in the Penaeus monodon from Indonesia. |
