SEATTLE — A conservation group plans to sue after net pens at a salmon farm in Washington state collapsed, spilling thousands of Atlantic salmon into Puget Sound.

The Wild Fish Conservancy says it gave Canada-based Cooke Aquaculture notice Friday that it will sue for violation of the federal Clean Water Act.

The company’s salmon farm off Cypress Island held 305,000 Atlantic salmon, a non-native species. Cooke has said it doesn’t yet know how many fish escaped.

The conservation group says the release poses a threat to struggling wild fish populations and the ecosystem. It alleges the fish spill violates federal pollution laws because it sent farmed salmon, dead carcasses and other debris into the water.

Cooke has blamed high tides for the disaster. A company spokeswoman did not immediately respond to a request for comment about the legal action.

State and tribal fisheries managers are urging anglers to catch as many as possible to protect native fish species.
