Abstract:The black‐lipped oyster Pinctada margaritifera is highly exploited in French Polynesia where the pearl industry relies mostly on spat collection, and therefore on resources available in the wild. Little is known of these resources, and population genetic studies would be useful to improve management. We used two methods, direct amplification of length polymorphism (DALP) and exon primed intron crossing (EPIC) to develop five new nuclear markers presenting length polymorphism. Although these markers remained anonymous after using blast on GenBank, they are codominant and follow Hardy–Weinberg equilibrium. Tests on related species or subspecies of Pinctada gave encouraging results.
