Shellfish aquaculture

For thousands of years, shellfish aquaculture has been part of the Pacific Northwest landscape. It is an economically important source of food and of cultural importance to Washington's coastal Indian Tribes. 

We work with a variety of stakeholders to protect and restore aquatic habitats, and plan for shellfish aquaculture alongside other shoreline uses. 

Permits for businesses

Please contact the Governor's Office for Regulatory Innovation & Assistance or your city or county planning department for the most up-to-date information. 

The Shellfish Interagency Permitting team also provides guidance about the state and local permitting process. 

Legal decisions

The legal foundation for shellfish aquaculture in Washington is complex and continually evolving.

We are just one of several state and federal agencies that has a policy and regulatory role in shellfish aquaculture.
