South Dakota's Game, Fish and Parks Commission has adopted an emergency rule on baitfish to help prevent the spread of Asian carp in the state.
The carp, often referred to as "jumping fish", are in the Missouri River below Gavins Point Dam and are spreading throughout the James, Big Sioux and Vermillion river basins.
The rule bans the taking of bait from the East and West Vermillion Rivers and Firesteel Creek.
The goal is to prevent bait dealers and anglers from inadvertently transporting young Asian carp to other waters.
