Genetic Characterization of Cupped Oyster Resources in Europe Using Informative Single Nucleotide Polymorphism (SNP) Panels
The Pacific oyster, Crassostrea gigas , was voluntarily introduced from Japan and British Columbia into Europe in the early 1970s, mainly to replace the Portuguese oyster, Crassostrea angulata , in the French shellfish industry, following a severe disease outbreak. Since then, the two species have b...
