What is the greatest threat to paddlefish?

The greatest threat is the loss of habitat for successful spawning and recruitment. Paddlefish need natural, free-flowing rivers to reproduce effectively. Without spawning habitat there’s really little that can be done to maintain viable populations over the long term. Water withdrawals from the Missouri and Yellowstone rivers are reducing available habitat. Protecting and enhancing habitat and flows in these rivers are critically important for the long-term survival of the stock.

Snag fisheries are regulated to ensure that the Yellowstone-Sakakawea stock is not overharvested. Illegal fishing is a major threat, however, and has been documented in several other states. Any illegal harvest activities should be reported.
