Oregon coastal waters are potential productive locations for various kinds of shellfish mariculture. The Estuary Shellfish Mariculture Planning Tool aggregates public records related to shellfish mariculture within estuaries in the state of Oregon. The tool enables users to review potential sites for viability of future shellfish mariculture operations. The tool can be used to generate interactive reports that can help to answer questions in the the shellfish plat lease pre-application questionnaire and subsequent lease application, as well as applications for other necessary local, county, and federal permits.
