The Olympia oyster (Ostrea lurida) is the only native oyster on the west coast of the US.
We are presenting research results on two ongoing efforts at the 16th International Conference on Shellfish Restoration, Charleston, South Carolina, USA.
Below are the two presentations and if you want to learn more about "Evidence of Ostrea lurida population structure in Puget Sound, WA" please have look at our preprint. Anyone can comment on the manuscript and we would love to hear any suggestions or questions.
Thursday December 11 - Genetics and Breeding for Restoration
Moderator: Jonathan Davis, Puget Sound Restoration Fund
4:00 “Identifying Local Olympia Oyster Stocks Useful for Restoration” Heare, J. et al.
4:20 “A Comparison of Breeding Methods for the Olympia Oyster, Ostrea lurida, Using Microsatellite Markers” Jackson, K. E. et al.
Alleviating Regulatory Impediments To Native Shellfish Aquaculture
Our approach is to simultaneously address local adaptation in three genetically differentiated populations of Olympia oysters by evaluating genotype-by-environment interactions. We will reciprocally transplant seed produced from wild parents collected from contrasting environments into all environments. This very large reciprocal transplant experiment can test for a home field advantage in survival, maturation and growth in Olympia oysters. The overall goals of this project are to increase our knowledge of local adaptation in Olympia oysters to address concerns that interbreeding between potentially maladapted cultured and wild stocks could negatively impact wild populations. Accordingly, in order to attain these goals, the specific objectives of this proposal are to 1) Evaluate fitness components and performance of seed from different origins in a reciprocal transplant experiment and 2) Characterize genetic and epigenetic markers associated with oysters from different origins in a reciprocal transplant experiment.
