Bighead Carp are originally from China, and can be found in large populations in many rivers there, including the Yangtze and Han Rivers

Suspected Hideouts

Bighead Carp are reproducing in populations along the Mississippi, Missouri and Ohio Rivers. They have been reported in states as far as California, Minnesota, and Florida. they were introduced to the Mississippi River when private hatchery ponds were washed out in the state of Arkansas in the 1970s or possibly they were let go into the wild when they were no longer needed by the fish farmers.

Crimes Committed

  • Big head carp eat blue green algae, zooplankton, and aquatic insects and larva, and does not have a true stomach so it must constantly eat. It is also thought that big head carp will compete for food with fish that are still in the larval stage, and fish populations decrease because the larval fish do not get enough food to survive.

    If we could eliminate Bighead Carp from our rivers, the native species would have a much better chance at survival. The Bighead Carp is always feeding and competes with larva for food, this makes their populations decrease because the larva don't get enough food to survive.
