Acipenser baerii is one of the most important sources of caviar production. However, the population of the A. baerii is constantly being reduced in recent years due to dam construction, overfishing, and water pollution. Insufficient molecular markers have limited the effective conservation and management of this species; In the present study, we reported the isolation and characterization of 34 SNP markers in A. baerii; The minor allele frequency ranged from 0.050 to 0.483. The observed heterozygosity varied from 0.100 to 0.933, while the expected heterozygosity ranged from 0.097 to 0.508. Polymorphic information content ranged from 0.090 to 0.375. Seven loci showed significant deviations from the HWE after Bonferroni correction; The novel polymorphic SNPs will be helpful for the future study on molecular-aided breeding, population conservation, and construction of genetic linkage map for this species.

Acipenser baerii是鱼子酱生产的最重要来源之一。然而，近年来由于大坝建设、过度捕捞和水污染，A. baerii 的数量不断减少。分子标记不足限制了该物种的有效保护和管理；在本研究中，我们报道了A. baerii中 34 个 SNP 标记的分离和表征; 次要等位基因频率范围为 0.050 至 0.483。观察到的杂合度从 0.100 到 0.933 不等，而预期杂合度从 0.097 到 0.508 不等。多态信息含量从 0.090 到 0.375 不等。Bonferroni 校正后，七个位点显示出与 HWE 的显着偏差；新的多态性SNPs将有助于该物种的分子辅助育种、种群保护和遗传连锁图谱构建的未来研究。
