January 8, 2025 — The State Board of Natural Resources for the U.S. state of Washington has voted to finalize a ban on finfish farming in state waters, codifying a ban that was first implemented unilaterally in 2022.
Momentum for a state ban on net pen aquaculture grew after the 2017 collapse of a Cypress Island fish farm operated by aquaculture company Cooke, which released hundreds of thousands of Atlantic salmon into state waters. Cooke was fined for the collapse, and ultimately, the state legislature passed a law ending Atlantic salmon farming in the state.
