: Native to eastern Asia. Found in large rivers, lakes and ponds.
: Mature at 6-11 years of age and at that time begin to reproduce annually. Females are capable of producing 129,000 to 1.18 million eggs each year.

Impact and Damage
: Black carp stay near or on the bottom and feed heavily on snails and mussels, posing a rish to native mollusks, many of which are endangered or threatened. Their life span exceeds 15 years and they can eat 3-4 pounds of mussels a day.
: Closely resembles the grass carp (Ctenopharyngodon idella
) in which both are similar in body shape, size and placement of fins.
