The geographic distribution of mitochondrial DNA haplotypes from Japanese river sculpin Cottus pollux large‐egg type (LE), collected from 55 locations in 22 rivers over most of the species’ range in Japan, was examined to assess for patterns of population genetic structure. The 87 haplotypes observed from C. pollux LE were distinguishable from C. pollux middle‐egg type and small‐egg type haplotypes from previously published research. Cottus pollux LE from each river were largely represented by diagnostic mtDNA haplotypes, with limited geographical associations of haplotypes, suggesting that each river must be treated as a separate management unit.
