A fish farm pen broke last month and released about 200,000 Atlantic salmon into the waters around the San Juan Islands in Washington state. National Congress of American Indians President Brian Cladoosby is among the many Native fishermen now trying to catch the invasive salmon. He says the fish threaten the wild Pacific salmon fishery with predation and the threat of disease. “These fish have infected the entire Salish Sea,” he said. The inadvertent release is one of several problems cropping up in the Pacific Northwest and in Canada involving salmon farms.
