Isolation and characterization of polymorphic microsatellite markers from Japanese grenadier anchovy (Coilia nasus)

Abstract

We isolated and characterized 12 novel polymorphic microsatellite loci for the Japanese grenadier anchovy (Coilia nasus) using the method of PCR-based isolation of microsatellite arrays. Sixteen individuals of C. nasus from Ariake Bay in Japan were genotyped using 24 PCR primers to characterize the polymorphism at each locus. The average number of the observed alleles per locus was 11.08 (ranging from 8 to 20). The observed heterozygosity values ranged from 0.562 to 1.0, and the expected heterozygosity values ranged from 0.647 to 0.969. Only one of the twelve loci deviated significantly from Hardy–Weinberg equilibrium, and linkage disequilibrium was not found in any pairs of the loci. These markers can be used to investigate the genetic structure of the C. nasus population.
