What federal act is aimed at controlling nonindigenous aquatic species to protect U.S. waters?

The Nonindigenous Aquatic Nuisance Prevention and Control Act is specifically designed to address the issue of nonindigenous aquatic species, which can pose significant threats to the ecosystems of U.S. waters. This act was enacted to prevent the introduction and spread of harmful invasive species that could disrupt local aquatic habitats, outcompete native species, and ultimately harm biodiversity and water quality.

It establishes a framework for cooperation among federal, state, and local agencies to manage and control aquatic nuisance species. Additionally, the act promotes research, elimination, and prevention strategies, highlighting its comprehensive approach to protecting aquatic ecosystems from invasive threats.

The other options listed do not primarily focus on nonindigenous aquatic species. The Plant Pest Act primarily deals with plant pests that impact agriculture, while the Clean Water Act is focused on regulating discharges of pollutants into U.S. waters to maintain and restore water quality. The Invasive Species Act, although relevant, does not specifically target aquatic species or provide a thorough framework like the Nonindigenous Aquatic Nuisance Prevention and Control Act does.
