The "Keep Finfish Free Act of 2025" aims to prevent federal agencies from authorizing or facilitating commercial finfish aquaculture operations within the United States' Exclusive Economic Zone (EEZ) . This measure would effectively halt the development of new finfish farming projects in federal waters without explicit congressional approval. The bill establishes a clear restriction on agency actions, including the issuance of permits. This prohibition is not absolute; it allows for such operations only if a Federal statute authorizing such action is enacted after the date of this Act's passage. The bill specifically defines "finfish" as aquatic finfish at any stage of its life cycle, explicitly excluding amphibians, seaweeds, other algae, or invertebrates like shellfish. "Commercial finfish aquaculture" refers to activities involving the propagation or rearing of finfish for commercial purposes.
