Abstract
Sequencing analysis of the partial control region ( c. 450 bp) detected 88 haplotypes from 249 individuals of Girella punctata collected from coastal waters of nine locations in the Japanese Islands. A single haplotype was the most numerous at all sampling locations, and no significant genetic difference was found among G. punctata samples collected from various locations ( F ST =−0·0274 to 0·0247) with high haplotype diversity and low nucleotide diversity, suggesting that G. punctata population had experienced a bottleneck followed by rapid population growth around the Japanese Islands and might be affected by larval dispersal in association with warm currents.
