Keep Finfish Free Act of 2025

This bill blocks federal agencies from permitting commercial finfish aquaculture (raising fish like salmon or tuna in pens or enclosures) in U.S. federal waters (the Exclusive Economic Zone). It directly affects commercial aquaculture companies seeking to operate in these federal waters, requiring them to wait for new federal law before any such activity can proceed. The key provision is a permanent ban on permits or actions authorizing such operations, unless Congress passes a new law specifically allowing it after this bill becomes law. The bill specifically excludes shellfish, seaweed, and other non-fish marine activities from this prohibition.
