Microsatellite markers for the half-fin anchovy Setipinna taty were developed from the enriched (CA)15 genomic library, and they were used for the population genetic studies of the half-fin anchovy from Chinese coastal areas. Samples were collected from five localities of the East China Sea and the Yellow Sea. Eleven simple sequence repeat markers were used to assess genetic differentiation in 30 individuals at each locality. As a result, 59 alleles were recorded over all loci with an average of 5.36 alleles per locus.
The genetic diversity of Setipinna taty, which is commercially fished in the China Sea, was studied based on mitochondrial DNA control region sequences. PCR was used to amplify the control region fragment in 100 individuals of S. taty collected from Weihai (WH), Yantai (YT), Zhoushan (ZS), Xiangshan (XS), and Ninghai (NH) in China. A control region fragment of 656 bp was successfully sequenced in these 100 individuals. The A+T content of this S. taty control region was 71.7%; 172 variable sites and 62 haplotypes were found.
