Bipartisan US Bill Targets Growing Threat Of Aquatic Invasive Species

A bipartisan group of U.S. lawmakers has introduced new legislation aimed at strengthening the country’s response to aquatic invasive species, a growing environmental and economic challenge affecting waterways, fisheries, and coastal ecosystems across the nation.

The proposed Aquatic Invasive Species (AIS) Control and Prevention Act, introduced by representatives from Michigan and Maryland, seeks to improve coordination between federal, state, and regional agencies while expanding support for prevention, rapid response, and long-term management efforts.

Lawmakers behind the bill said invasive species are increasingly threatening major ecosystems such as the Great Lakes and the Chesapeake Bay, while also harming fisheries, tourism, recreation, and local economies. Species including invasive carp, blue catfish, quagga mussels, and snakehead fish have spread across U.S. waterways in recent years, disrupting native ecosystems and creating costly environmental impacts.

If approved, the legislation would establish a grant program to fund research, technology development, and demonstration projects focused on controlling or eradicating invasive aquatic species. The bill also aims to streamline coordination among agencies and strengthen state-led management programs to improve response times and prevention measures.

The proposal has already gained broad backing from the fishing and boating industries, with 18 national organizations supporting the measure. Industry groups described the bill as the most significant modernization of federal aquatic invasive species policy in decades, emphasizing the need for stronger prevention systems and faster intervention strategies.

Supporters argue that the legislation reflects growing recognition that invasive species are not just environmental concerns, but also major economic risks for communities dependent on fishing, boating, tourism, and outdoor recreation.

As climate change, shipping activity, and interconnected waterways continue to increase the spread of invasive species, policymakers say stronger national coordination will be critical to protecting U.S. ecosystems and preserving long-term economic resilience in coastal and freshwater regions.
