  "Managing Hull Transport of Aquatic Invasive Species" Proceedings of May 11, 2005 Workshop in San Francisco, California. 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.
  
  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.

AVAILABLE VIA STANDARD MAIL BY REQUEST:

• Clean Boating Poster
  California Sea Grant College has produced the lighthearted, 18" x 24" poster, "Make Every Day a Clean Boating Day!" The poster highlights the 25 most important tips for preventing boating pollution. Tips are organized under fuel & oil, painting & sanding, sewage & garbage, and hull maintenance. Spill reporting information is included, too. The four-color illustrations keep the tone light and fun.
  We are able to supply complimentary copies in modest amounts for posting at marinas, supply stores, boat shows or similar locations where many boaters can see them. Supplies are not sufficient to provide copies for individuals. The posters are NOT weatherproof.
  To inquire about availability, plese let us know how you will use the poster and how many copies you need. You may write, fax, or email.
  
  

 

 

Executive Producer: Leigh Johnson - Producer/Director: Mike Poe
California Sea Grant College Program Report No. T-055

Video content is based on a series of research and education projects conducted by Marine Advisor Leigh T. Johnson and Program Representative Jamie A. Gonzalez of the UC Sea Grant Extension Program in San Diego, where copper-based hull paints have caused levels of dissolved copper in bays to be above EPA limits.

The 30-minute documentary, in both English and Spanish, was produced in cooperation by the University of California Agriculture and Natural Resources Communication Services and the California Sea Grant Extension Program.

Information intended for:
• Boat owners, repair and maintenance businesses
• Marina, yacht club, port and harbor managers
• Government and regulatory agencies and policy makers
• Marine and environmental organizations

•  "What You Need to Know about Nontoxic Antifouling Strategies for Boats", by Leigh Taylor Johnson and Jamie Anne Miller, Report # T-049, California Sea Grant College Program, October 2002.
  This educational booklet summarizes:
  1) Technical information on currently available nontoxic antifouling strategies for recreational boats;
  2) Copper antifouling paint policies in the U.S. and Europe;
  3) Toxic effects of copper on marine life.
  As new regulations are passed to reduce copper levels in urban boat basins in San Diego and Orange Counties, the UC Sea Grant Extension Program’s educational outreach will help boaters switch to nontoxic antifouling strategies. This will help to preserve the marine life and clean water that support the birds and fish that boaters enjoy in a day on the water!
