QUAGGA MUSSELS
The invasive Quagga mussel has been found in California, according to the California Department of Fish and Game. For more information on preventing the spread of Quagga mussels and for other educational materials please see the California Department of Fish and Game website.

Managing Hull Transport of Aquatic Invasive Species
Aquatic invasive species (AIS) attach to all types and sizes of vessels. Measures to prevent and control the hull transport of AIS are necessary as they can have significant ecological and socio-economic impacts.

The UC Sea Grant Extension Program has published a bilingual poster and Fact Sheet. They explain problems caused by hull-borne invasive species and how to reduce the risk of transporting them on recreational boat hulls. Colorful photos of invasive species will help boaters identify them and report them to the appropriate agencies. Please contact Leigh Johnson at ltjohnson@ucdavis.edu for copies of the poster and Fact Sheet or to download the Fact Sheet please see our Publications page.


2005 Workshop
The University of California Sea Grant Extension Program collaborated with the California State Lands Commission to lay a foundation for solutions by convening a Workshop to educate participants, learn from them and ask for recommendations. This coordinated approach was chosen because hull transport of AIS is a complicated issue affecting commercial and recreational vessels.

The Workshop took place on May 11th, 2005 in San Francisco. To ensure that the recommendations reflect the best available information and consider the concerns of affected parties, representatives from the shipping, boating and coating industries; vessel owners; port, harbor, and marina managers; state and federal agencies; research community and environmental organizations participated in the Workshop.

Workshop Goals:
• Educate stakeholders and facilitate the exchange of perspectives on managing hull-borne invasive species, fouling growth and coastal water quality from the commercial shipping and recreational boating perspectives.
• Develop recommendations on managing the risks associated with the hull transport of invasive species as well as feasible, effective strategies for preventing associated introductions.
• Determine recommendations for action such as research, education, outreach, management measures and policies needed to prevent and control AIS introductions and establishment.

Workshop findings have been incorporated into the White Paper, Managing Hull-Borne Invasive Species and Coastal Water Quality for California and Baja California Boats Kept in Saltwater, by the University of California Sea Grant Extension Program to extend information on managing hull transport of AIS and on water quality issues related to antifouling paints for recreational vessels.
