Early Detection Monitoring Manual for Quagga and Zebra Mussels, CASGEP and UC Cooperative Extension: Carolynn S. Culver, Ph.D., Sabrina L. Drill, Ph.D., Monique R. Myers, D.Env, Valerie T. Borel. Publication No. T-069

Quagga (Dreissena bugensis) and zebra (D. polymorpha) mussels have caused numerous economic and ecological impacts where they have been introduced. This manual was developed to help direct early detection monitoring efforts for small lakes, reservoirs and streams in California that are believed to be free of invasive quagga and zebra mussels. The methods presented are intended for citizen volunteer groups involved with or interested in monitoring aquatic organisms. Citizen help with identifing the extent of the spread of these invasive species through early detection monitoring is vital for minimizing the occurrence of additional infestations and for the application of effective treatment methods. While the manual addresses the situation in California, the majority of the information is broadly applicable to other states and countries. It is hoped that it will facilitate proactive measures to minimize the impacts of these and other aquatic invasive species in California and elsewhere.

Quagga/Zebra Mussel Monitoring: These internationally recognized pests have caused significant impacts on water delivery systems, fisheries and ecosystems, with control costing millions of dollars annually in many states and countries. Relatively recent invaders to California, many are working toward minimizing their impacts and spread. To assist the Department of Fish and Wildlife, Culver and her colleagues also have developed an associated pilot training program on this topic. Culver conducts research to better understand recruitment dynamics and early detection monitoring to aid management of these pests.
