South Dakota has closed creeks, streams and rivers to the taking of baitfish by traps, nets and seines to prevent the spread of aquatic nuisance species such as Asian carp.
Biologists say young Asian carp closely resemble some popular bait fish species and may be hard to recognize when mixed with other fish.
The South Dakota Game, Fish and Parks Commission approved the proposal Thursday.
It affects the Black Hills trout management area and the following counties: Aurora, Beadle, Brown, Bon Homme, Clay, Davison, Edmunds, Faulk, Hand, Hanson, Hutchinson, Jerauld, Lincoln, McCook, McPherson, Miner, Minnehaha, Moody, Sanborn, Spink, Turner, Union and Yankton.
The use of hook and line to take bait fish species will still be allowed, and bait could be trapped from lakes, ponds and wetlands.
