ONTARIO, Ore. — Invasive shellfish have been found in Oregon. Oregon Department of Fish and Wildlife boat inspectors found quagga mussels on a motorboat in Ontario, Oregon.
The ODFW said the Pacific Northwest is one of the last regions in the country where the invasive bivalve has popped up.
The suspected boat had been on Lake Mead on the Nevada-Arizona border.
The ODFW says zebra and quagga mussels can have a devastating effect on local ecosystems by filtering out and consuming the food that native juvenile and larva fish rely on.
