Aquatic Invasive Species
Non-native aquatic species—plants, fish and animals—are invading
California’s coastal and inland waters. These pests can increase dramatically
under the right conditions, displacing native species, clogging waterways, and
impacting navigation and recreation. Once introduced, they are nearly impos-
sible to eliminate. Aquatic invasive species such as Hydrilla, Egeria densa,
water hyacinth, quagga and zebra mussels can be accidentally transported by
recreational boaters when caught in propellers, intakes or attached to hulls.
Controlling these species is a multi-million dollar problem in California.
You can help prevent the introduction and spread of non-native species from
one body of water to another by cleaning, draining and drying your boat and
by taking these steps:
Avoid chopping vegetation with your boat’s propeller.
Inspect your boat and remove aquatic plants or animals before you leave
any body of water.
Inspect all exposed surfaces. Small mussels feel like sandpaper to the touch.
Wash the hull of each watercraft thoroughly.
Drain all water and dry all areas.
Drain and dry the lower outboard unit.
Clean and dry all live-wells.
Empty and dry any buckets.
Dispose of all bait in the trash.
There are specific drying times that need to be calculated by each boater.

Be sure to report new infestations of non-native aquatic species to the
U.S. Fish and Wildlife Service at 1-877-786-7267. Visitwww.dbw.ca.gov
more information on quagga and zebra mussels or call 1-866-440-9530.
Restrictions on California’s
waterways, to prevent the spread
of quagga and zebra mussels,
are determined by county or
local municipalities, and in some
cases, the Department of Parks
and Recreation. Boaters should
check ahead to see whether boat
inspections will be required.

DMV MUSSEL FEE
California registered recreational
vessels using fresh water bodies
within the state are required to
display a “Mussel Fee Paid” sticker
on the hull next to the current
registration sticker. Paying the
Mussel Fee does not entitle vessels
to bypass inspections or fees for
inspections conducted by individual
reservoir owners or managers.
