摘要：

The gnomefish (Scombrops boops) is a member of the percoid family Scombropidae, which includes a single genus and three to four species worldwide. Since little is known about the ecology of this species, here, sequencing analysis of the cytochrome b gene (1141 bp) in mitochondrial DNA detected 101 haplotypes from 186 individuals of S. boops collected from waters at seven localities around the Japanese archipelago. A single haplotype (Sb2) was the most abundant in the combined populations of S. boops from various localities. Genetic population structure analyses revealed no significant differences among these populations (Fst = -0.0313-0.0195; Phi st = -0.0505-0.0615) with high haplotype diversity and low nucleotide diversity. This suggests that S. boops around the Japanese archipelago constitutes a single population, and indicates that the genetic structure of this population may be influenced by larval and egg dispersal in association with warm currents.
