摘要： Yellowtail kingfish, Seriola lalandi, is a globally distributing pelagic marine fish species. In recent years, the wild population has suffered drastic decline due to overfishing and environmental deterioration. Thus, the sustainable utilization and conservation management for this species should be implemented urgently. In the present study, we developed SNP markers using 2b-RAD sequencing method from 33 individuals of yellowtail kingfish. Wherein, 100 high-quality SNP markers were obtained based on high throughput sequencing and stringent SNP filter process. The minor allele frequency of these SNPs ranged from 0.0126 to 0.4957. The observed heterozygosity and expected heterozygosity ranged from 0 to 0.9914 and 0.0249 to 0.5000, respectively. The inbreeding coefficient varied from - 0.9828 to 0.7882. Among these SNPs, 10 loci deviated significantly from Hardy-Weinberg equilibrium after Bonferroni correction. These novel SNP markers will serve as valuable tools for population genetics evaluation and natural resources conservation of yellowtail kingfish.
