Shellfish & the Environment Research Symposium

On December 8, 2014, over 300 people attended a symposium on shellfish and the environment, held in Lacey, Washington. The symposium brought together scientists and other experts to share the latest research and information on shellfish and the environment. Speakers covered a range of topics, including aquaculture planning and permitting, shellfish ecosystems, and seagrasses. The purpose of the meeting was to provide a baseline of current knowledge on shellfish issues in Washington State and begin a discussion of those issues.

Where available, talk titles in the following symposium agenda link to presentations.
