Description |
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. |
