Development and identification of 131 SNP markers in Sthenoteuthis pteropus (Steenstrup)

The orangeback flying squid, Sthenoteuthis pteropus, is a species of significant potential value that widely distributed in the tropical and temperate waters Atlantic Ocean. There have been no reports population genetics effective molecular markers for this due to lack reliable information regarding its genetic structure many individual differences, as well complex changeable life history. Therefore, development auxiliary would contribute development, sustainable utilization, protection species. In study, 131 novel single nucleotide polymorphism (SNP) were developed by double digest restriction-site associated DNA sequencing (ddRAD-Seq). observed heterozygosity (Ho) expected (He) ranged from 0.00 0.80 0.18 0.50, respectively. content (PIC) 0.50. None marker locations significantly deviated Hardy–Weinberg equilibrium (p > 0.05) after Bonferroni correction. These polymorphic SNPs will be important further analysis heredity S. pteropus scientific management.
