Abstract

We isolated 40 microsatellite markers for the endangered Atlantic, and Pacific goliath grouper, Epinephelus itajara and E. quinquefasciatus. Loci were characterized using samples of E. itajara (n = 52) and E. quinquefasciatus (n = 10). Twenty-nine loci were polymorphic. For E. itajara and E. quinquefasciatus, respectively, mean numbers of alleles per locus were 5.2 and 4.3 and mean observed heterozygosities were 0.46 and 0.63. Three loci departed from Hardy–Weinberg equilibrium expectations in the E. itajara sample. Allele frequencies differed significantly between the two taxa for each polymorphic locus.
