The Arizona Department of Agriculture has banned the transport of the the aquatic nursery plant Aegagropila linnaei, a green algae common in the aquatic plant and aquarium trade and more commonly known Marimo balls, Cladophora ball, moss ball or lake ball.
The action comes after the Department of Agriculture and the Arizona Game and Fish Department in early March found Marimo balls infested with invasive zebra mussels in a number of Arizona pet stores. Zebra-mussel-infested Marimo/moss balls have thus far been detected by state agricultural or wildlife agencies in 26 states. They are imported from at least 18 countries under a permit from the U.S. Department of Agriculture.
