Who We Are

The Northwest Aquaculture Alliance (NWAA) represents the leading aquaculture producers and support-related businesses in the Pacific region–including Washington, Oregon, Idaho, Montana, Hawaii, British Columbia, and Alaska.
Alliance members share a vision of feeding the world with high-quality, sustainably and responsibly produced, nutritious fish, shellfish, and sea vegetables–farmed in marine waters, freshwater, or in land-based operations that our members offer to local, regional, and global markets.

Why Aquaculture?

The world needs more protein. And, as we all learned from the pandemic, and realize during times of global unrest, the United States cannot rely solely on imports to meet consumer demand for seafood. It’s time to grow it here. We can. We must.

Currently, the USA ranks 16th in the world in aquaculture production. The Pacific region, with its abundant supply of natural resources, know-how, and hard-working people, can—and should—produce enough farmed seafood to help the U.S. compete with imports from other aquaculture-producing countries.
Aquaculture currently provides more than half of the seafood consumed worldwide—and that percentage is increasing as global demand for seafood continues to rise and wild fisheries are fully exploited.
