侏儒鱼（Scombrops boops）是鲈科的一员，在世界范围内包括一个单一的属和三到四个物种。由于对该物种的生态学知之甚少，在此，对线粒体DNA中的细胞色素B基因（1141 bp）进行测序分析，从186个个体中检测到101种单倍型。从日本列岛周围的七个地点的沃茨收集的boops。单一单倍型（Sb 2）在S.来自各地的boops。群体遗传结构分析表明，这些群体间的遗传差异不显著（Fst = -0.0313-0.0195; Phi st = -0.0505-0.0615），具有较高的单倍型多样性和较低的核苷酸多样性。这表明S.日本列岛周围的boops构成了一个单一的群体，并表明该群体的遗传结构可能受到影响的幼虫和卵扩散与暖流。
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.
