Last week, the Wisconsin Department of Natural Resources put out an alert to destroy and dispose of certain commercially available moss balls. That’s because some of the small, fuzzy flora — which are a common addition to aquariums — were found to be infested with zebra mussels.
Zebra mussels are considered by the U.S. Fish and Wildlife Service to be one of the most destructive invasive species on the continent.
For more on the threat the mussels pose, and what to do if your moss balls are infested, WORT Producer Jonah Chester spoke with Wesley Daniel — coordinator of the U.S. Geological Survey’s Nonindigenous Aquatic Species Database.
