摘要： The yellowfin seabream (Acanthopagrus latus Houttuyn 1782) is a commercially and ecologically important Sparidae species in the northern South China Sea. However, environmental pollution and overfishing result in serious decline of seabream natural population and germplasm degradation in recent years. In the present study, to promote the molecular-assisted selection (MAS), population selection, and enhancement and releasing of A. latus, the 112 novel single nucleotide polymorphism (SNP) markers were isolated by restriction-site associated DNA (RAD) sequencing, and then the polymorphism of these SNP markers were verified in 36 wild individuals. The results showed that the observed heterozygosity (Ho) and expected heterozygosity (H-E) varied from 0.0278 to 0.6389 and 0.0540 to 0.4996, respectively. The PIC value and minor allele frequency (MAF) were between 0.0526 and 0.3748 and 0.0278-0.4861, respectively. Moreover, the F-IS value ranged from - 0.2941 to 0.9449. Thirty-seven loci revealed noteworthy deviations from the Hardy-Weinberg equilibrium (HWE) after Bonferroni correction (p < 0.05), but no prominent linkage disequilibrium was detected. These novel developed SNPs will be useful for breeding, genetic diversity analysis, enhancement and releasing studies of seabream.
