• Asian carp are a significant threat to the Great Lakes  because of their size, fecundity, and ability to consume  large amounts of food.
• Asian carp can grow to 100 pounds  and up to four feet. They are well-suited to the cold  water climate of the Great Lakes region, which is similar  to their native Eastern Hemisphere habitats.
