Asian Carp

A Polaroid style image of a jumping Asian carp. The fish is silver.

Other names: Asian carp refers to multiple species: bighead carp (Hypophthalmichthys nobilis), silver carp (Hypophthalmichthys molitrix), grass carp (Ctenopharyngodon idella), and black carp (Mylopharyngodon piceus)

Where did it come from?

All four of these fish were introduced from Asia in the 1970s to control weed growth in both aquaculture and canals.

Why is it invasive?

Silver carp are up to 3 feet long and can weigh up to 60 pounds; bighead carp are up to 5 feet long and weigh up to 100 pounds.

When disturbed by motor boats, they can jump out of the water, damaging boats and harming passengers.

Their explosive population growth reduces the number and health of other fish you like to catch.

They eat lots of plankton, reducing the amount of food available for other species in the aquatic food chain.

How do you prevent its spread?

Don’t release an Asian carp into another body of water. It is Illegal to move or possess a live Asian carp without a permit. If you catch an Asian carp, don’t throw it back into the water.
