The central stoneroller (Campostoma anomalum) is an abundant, widespread and sexually dimorphic stream minnow that is a useful model for mating system studies as well as a sentinel species for understanding population-level processes for fishes in headwater communities. We developed one genomic library enriched for dinucleotide repeats and isolated 48 putative, novel microsatellite loci. Of those, we present 32 polymorphic and independent microsatellite markers with 3 to 16 alleles per locus and heterozygosity ranging from 0.23 to 0.95. Hence, these markers will be useful for future behavioural, ecological and evolutionary studies using C. anomalum.
