West Coast Shellfish Aquaculture – Economic Impacts, Barriers to Entry and Opportunities for Expanded Production

Shellfish associations, economic development councils, regulators and other organizations have struggled to obtain accurate economic and production data for west coast shellfish for decades. PSI and partners at Northern Economics, Inc. are currently conducting research to quantify the economic impact of shellfish aquaculture and identify barriers limiting expansion of the industry.

Commercial shellfish license holders in Washington, Oregon and California were surveyed for company revenues and expenditures, number of employees, and tideland acres in shellfish production. Survey responses were summarized and economic data area being used to build and Input-Output (I/O) model for shellfish aquaculture. An I/O model depicts inter-industry relations of a regional economy. It shows how the output of one industry is an input to each other industry. Development of the Input-Output model is underway, and will yield multipliers and indirect employment estimates.
