The Michigan Department of Natural Resources has developed a video to help anglers identify young Asian carp and prevent them from getting into the Great Lakes.
Asian carp are large, voracious fish that have been migrating toward the lakes from Southern rivers. The two most feared varieties are bighead and silver carp.
Officials fear that juvenile Asian carp will find their way into the bait supply if anglers confuse them with common baitfish such as gizzard shad and emerald shiners.
The new video displays five characteristics of juvenile Asian carp. They include color, scales, eyes, mouths and keels.
It advises anglers who think they might have the carp in their bait buckets to throw them in the trash or take them to the DNR for inspection.
