Abstract

Until recently, Fenneropenaeus penicillatus was considered a commercial shrimp species. However, in 2005, it was included on the Red List as an endangered species by the Chinese government. In this study, 19 new microsatellite markers in F. penicillatus were developed and tested in samples of 32 wild individuals from Nanao, China. Twelve loci were polymorphic and 7 were monomorphic. Of the 12 polymorphic loci, the number of alleles per locus ranged from 3 to 6, with an average of 4.42 alleles per locus. The polymorphism information content ranged from 0.302 to 0.670, with a mean of 0.4817. The observed and expected heterozygosities ranged from 0.2250 to 0.8889 and from 0.1111 to 0.7750, respectively. Significant deviations from Hardy-Weinberg equilibrium (HWE, adjusted P < 0.0042) after a Bonferroni correction were observed in 3 loci (NA-9, NA-57, and NA-64), whereas the other 9 loci were in HWE. These new microsatellite markers will be useful in further research on the population genetic structure of F. penicillatus.
