Arizona Game and Fish Department.
New state regulations to help prevent the spread of quagga mussels and zebra mussels went into effect in Mar 2010. These regulatory measures, known as "Director's Orders," were authorized by the Aquatic Invasive Species Interdiction Act passed by the Arizona Legislature in 2009. The orders contain a list of aquatic invasive species for Arizona, a list of waters where aquatic invasive species are present, and mandatory conditions for the movement of watercraft.
