On April 20, the National Marine Fisheries Service (NMFS) released a Biological Opinion (BiOp) finding that three additional pesticides, carbaryl, carbofuran, and methomyl, harm salmon and steelhead protected under the Endangered Species Act (ESA). The BiOp prescribes measures necessary to keep these pesticides out of salmon waters in Washington, Oregon, California, and Idaho. It is the second such plan issued in the last six months under a court settlement with fishermen and conservationists, filed by the non-profit law firm Earthjustice. The previous BiOp identified three organophosphate insecticides: chlorpyrifos, diazinon, and malathion.
“These pesticides are designed to kill insects on agricultural crops, but when they get into the water system, they also kill aquatic insects that salmon feed on.” said Angela Somma, who heads the NMFS endangered species division.
