Aquatic Invasive Species (AIS) are a threat to aquatic resources in many streams and lakes in New Jersey. The impacts to water resources start with the exclusion or replacement of native aquatic plants, which can eventually lead to water quality impairments, disruption of the food web, and a decline in the quality of the fishery. AIS can affect water uses including boating, swimming, human and animal health, drinking water quality, fish and wildlife habitat, commercial and sport fishing, irrigation, aesthetics and even real estate values.

The objectives of the Aquatic Invasive Species Management Program are to increase awareness of AIS, and teach residents how to identify, manage and control AIS. This is accomplished through education, outreach and research about aquatic invasive species in New Jersey.
