Abstract

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 (Ho) ranged from 0.0864 to 0.5000, expected heterozygosity (He) 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.
