This research focuses on the dynamics and potential effects of interactions between farmed and wild populations of geoduck clams.  The study will examine genetic differences between the two groups and compare their various reproductive and life history parameters. Results will enable state and tribal workers to proactively manage wild geoduck for resource sustainability and help ensure that stocks of these commercially valuable shellfish will remain abundant for future generations of harvesters.
