Red sea bream is a commercially valuable fish that is used as ingredients in the food industry. To prevent a decrease in fishing yield, farmed red sea bream is released. However, this may cause a decrease in the genetic diversity of wild populations, so systematic resource management is required. In this study, 68 single nucleotide polymorphism (SNP) markers were developed using a genotyping-by-sequencing (GBS) analysis. The minor allele frequency (MAF) ranged from 0.1802 to 0.5000, the observed heterozygosity (H_o) ranged from 0.0864 to 0.5000, expected heterozygosity (H_e) ranged from 0.2955 to 0.5000, and the polymorphism information content (PIC) ranged from 0.2518 to 0.3750. Of these SNPs, 25 loci significantly deviated from the Hardy–Weinberg equilibrium after a Bonferroni correction (p < 0.00074). These SNP markers will be useful for the further genetic analysis of the red sea bream population.

红鲷鱼是一种具有商业价值的鱼类，用作食品工业的原料。为了防止捕捞量下降，养殖的红鲷鱼被放流。然而，这可能会导致野生种群遗传多样性的减少，因此需要系统的资源管理。在这项研究中，使用测序基因分型 (GBS) 分析开发了 68 个单核苷酸多态性 (SNP) 标记。次要等位基因频率（MAF）范围为0.1802至0.5000，观察杂合度（H _o）范围为0.0864至0.5000，预期杂合度（He _）范围为0.2955至0.5000，多态性信息内容（PIC）范围为0.2518至0.5000。 0.3750。在这些 SNP 中，25 个位点在 Bonferroni 校正后显着偏离 Hardy-Weinberg 平衡 ( p  < 0.00074)。这些SNP标记将有助于红鲷种群的进一步遗传分析。
