Genetic stock structure and historical demography of Indian oil sardine, a commercially and ecologically important
small pelagic fish, was studied using mitochondrial control region and Cytochrome C Oxidase I (COI)
sequences. A 758 bp portion of the control region in 287 individuals and a 576 bp portion of the COI gene in
291individuals from 10 locations along the distribution range were amplified resulting in 236 and 84 haplotypes,
respectively. The high haplotype and low nucleotide diversity values (0.99 and 0.19 for control region and 0.85
and 0.004 for COI, respectively) are characteristic of populations having undergone a demographic expansion.
Genetic differentiation, ΦST, was low and insignificant between populations using both control region and COI
gene markers. Mismatch analysis showed a recent demographic and spatial expansion coinciding with the late
Pleistocene epoch. Mantel tests revealed the lack of isolation by distance which is attributable either to high levels
of migration overriding the effect of genetic drift or to insufficient time for accomplishing a balance between
migration and drift after a recent range expansion.
