摘要	Identification of population units is crucial for management and monitoring programs, especially for endangered wild species. The roughskin sculpin (Trachidermus fasciatus Heckel) is a small catadromous fish and has been listed as a second class state protected aquatic animal since 1988 in China. To achieve sustainable conservation of this species, it is necessary to clarify the existing genetic structure both between and within populations. Here, population genetic structure among eight populations of T. fasciatus were analyzed by using 16 highly polymorphic microsatellites. High levels of genetic variation were observed in all populations. All pairwise F (ST) estimates were significant after false discovery rate correction (overall average F (ST) = 0.054). Furthermore, both STRUCTURE and discriminant analysis of principal components (DAPC) analysis showed that the eight populations were grouped into six clusters. BAYESASS analysis showed generally low recent and asymmetric migration among populations. All these results suggested significant genetic structure across populations. However, there was no isolation by distance relationship among populations, likely resulting from barriers to gene flow created by habitat fragmentation. Our results highlight the need for in situ conservation efforts for T. fasciatus across its entire distribution range, through maximizing habitat size and quality to preserve overall genetic diversity and evolutionary potential.
