Why are Asian Carp a problem?
- Asian carp juviniles closely resemble several bait and rough fish species.
- These fish are highly adaptive, prolific spawners, quickly outgrow potential controls by predation and compete with
native fish for food resources which includes native snails and mussels.
- Silver carp pose a physical danger because of their leaping ability. These large fish may collide with boaters,
personal watercraft, or water skiers and cause serious injury.
How are Asian Carp spread?
- Many times Asian Carp are mistaken and used as bait when they are juviniles.
