Atlantic salmon farming has been banned from Washington state waters.
Gov. Jay Inslee signed the ban on non-native fish farms into law Thursday morning in Olympia.
“These present a risk to our wild salmon runs that we cannot tolerate,” Inslee said.
The move comes eight months after an ill-fated fish farm near Anacortes started to come undone in a strong current on an otherwise calm summer day. The floating farm, owned by New Brunswick, Canada-based Cooke Aquaculture, tore apart a month later, letting as many as 250,000 Atlantic salmon escape into Puget Sound.
