Asian carp (bighead, black and silver carp) have caused substantial harm in other areas of the country. You can make sure they don’t do the same in Wyoming by never moving fish from one water to another.
Origin: Asia and Russia
Distribution: They are widespread throughout the eastern United States, and have recently been found near the Great Lakes.
Impacts: They out-compete native fishes, reduce forage for other fish, and can transmit disease. Silver carp are also known for their ability to jump great distances out of the water when boats travel near them, causing injury to boaters.
Dispersal: They are transported downstream in water and overland in bait buckets and illegally by people.
Characteristics: Large; 39-40 inches and 40-50 lbs, thick bodied with blunt head.
