range includes all the Maritime Provinces. It is also cultivated in Quebec and Newfoundland. Despite their_x000D_
importance, we know very little about their population-genetic structure. This information is critical not only to_x000D_
the management of wild oyster introductions and transfers, but also in the establishment and management of_x000D_
hatchery broodstock programs. L'Étang Ruisseau Bar Ltd. (ERB) owns and operates Atlantic Canada's largest_x000D_
shellfish hatchery, exporting seed to all Atlantic provinces. The proposed project aims at finalising a thorough_x000D_
analysis and publication based on cutting-edge population-genomics analyses that allowed quantifying key_x000D_
features of wild oyster populations, including critical information such as the amount and extent of genetic_x000D_
differentiation, estimates of effective population size, and evidence for local adaptation. Our results to date_x000D_
showed that despite the massive rehabilitation transfers of disease-resistant PEI broodstock, there is highly_x000D_
significant population differentiation at local and regional scales. These results represent a profound shift in our_x000D_
view of oyster diversity in Eastern Canada and raises questions about the origin and maintenance of oyster_x000D_
genetic diversity in the face of considerable historical and contemporary disturbance. The proposed project will_x000D_
extend ongoing analyses to uncover the driving forces behind this pattern of diversity. We will develop specific_x000D_
recommendations for current broodstock collection activities and breeding program, as well as prepare and_x000D_
submit our results for publication. This will enhance ERB's broodstock management strategy, increasing the_x000D_
performance of their seed in aquaculture production, inform their selective breeding program, and minimize the_x000D_
potential genetic impacts of large-scale transfers on neighbouring wild populations., program purpose french : The eastern oyster, Crassostrea virginica, is a commercially and ecologically important species whose natural_x000D_
