摘要：

The population structure of the only Litopenaeus species occurring in Brazilian waters, the white shrimp L. schmitti, was surveyed by screening six microsatellite loci. High diversity (H-E = 0.863; average number of alleles per locus = 37.8) was found across eight geographical locations (2degreesS to 27degreesS). Estimates of overall F-ST(0.0060) were low but significantly different from zero (P < 0.05). F-ST pairwise estimates and AMOVA revealed a significant discontinuity around a major biogeographical boundary, near Cabo Frio, at 23degreesS. This separation may have been caused either by historical or on-going hydrogeographical and/or selective factors.
