List of Ohio's Aquatic Invasive Species

Aquatic invasive species include plants and animals living in and degrading the quality of our waterways. Species like zebra mussels, bighead and silver carp, and curlyleaf pondweed are changing the dynamics of our underwater habitats. No waterway, from Lake Erie to the Ohio River, is immune to the negative impacts of aquatic invasive species, and the Ohio Department of Natural Resources, along with many state and federal partners, are continually monitoring these risks.

AIS may live entirely within or partially in an aquatic habitat. Below is a list of some Ohio's top threats. The list is not fully inclusive and the USGS maintains an additional list of AIS in the U.S.
