Background Pseudobagrus brevicorpus is an endangered species in Korea. The development of genetic markers and geneticinformation regarding the populations of this species are needed to establish conservation strategies. Objective As part of the conservation of P. brevicorpus, a 12-microsatellite marker was developed using next-generationsequencing (NGS) to provide current genetic population information. Methods Microsatellites from P. brevicorpus were identified by NGS analysis. Genetic diversity and genetic structureanalysis of six populations (Seojeong Stream [SJ], Gokgang Stream [GK], Jaho Stream [JH], Daega Stream [DG], NamRiver [NG], and Deokcheon River [DC]) of P. brevicorpus were conducted using the newly developed microsatellite marker. Results NGS generated 10,347,578 reads and identified 659,507 simple sequence repeats. Twelve microsatellites were successfullyamplified and verified in 30 individuals of P. brevicorpus. The genetic diversity of the six P. brevicorpus populationsin terms of the number of alleles ranged from 3.667 to 7.111. All populations except DG deviated significantly fromHardy–Weinberg equilibrium (HWE) at one or more loci. The genetic distances of the six populations showed the closestrelationship between the SJ and GK populations (independent Stream populations), and there was a close relationship withthe JH population among the Nakdong River. Structure analysis showed that P. brevicorpus is largely divided into two groups. Conclusions The developed microsatellite marker will be used to provide basic genetic data of P. brevicorpus. Genetic diversityand structure analysis of the population will provide useful information for conservation management of P. brevicorpus
