“The Dreissena [zebra and quagga mussels] is perhaps better
fitted for dissemination by man and subsequent establishment
than any other freshwater shell; the tenacity of life, unusually
rapid propagation, the faculty of becoming attached by string
byssus to extraneous substances and the power of adapting itself
to strange and altogether artificial surroundings have combined

world.” (Kew, H.W. 1893) The Washington Department of Fish and
Wildlife (department) and the Washington State Patrol (WSP)
