摘　　要：Microsatellite markers with polymorphic advantages are widely used in the exploration and utilization of marine fishery resources.In this study,16 polymorphic microsatellite markers were used to evaluate the diversity and population structure of Setipinna tenuifilis,a nearshore fish of economic and ecological value in the western Pacific Ocean and Indian Ocean.The genetic diversity of S.tenuifilis showed a high level[mean Na(number of alleles)is 23.25,mean Ho(observed heterozygosity)is 0.639,mean R_(a)(allelic richness)is 11.625,and the polymorphic information content(PIC)is 0.844]similar to other Clupeiformes fish species.The nine wild S.tenuifilis populations showed significant differentiation(F_(ST)ranging from 0.00384 to 0.19346)and were generally divided into southern and northern populations based on genetic structure,except for the Zhoushan population,which exhibited genetic mixture.Our results provide fundamental but significant genetic insights for the management and conservation of S.tenuifilis fishery resources.
