Carp
     
 

Arrival:
Carp are native to Asia. These fish were brought to the United States in the late 1800s. The carp was part of a government program to raise fish for food. Today, carp are found throughout North America.

Attack:
Carp look like giant goldfish. They hang out in shallow, weedy waters in ponds and lakes. Carp munch a mixture of plant and animal material off the pond bottom. They're very messy eaters! Carp swish their tails back and forth as they feed, stirring up mud. This changes the quality of the waters where they live. Carp also tear up plants as they gobble down food.

As a result, carp have driven away native species of fish that like to live in cleaner waters. They've also destroyed plants used for food or shelter by other fish and waterfowl. Some people do enjoy catching and eating carp. In many places, though, the carp's diet makes them taste bad. They may even be unsafe to eat. Their bodies may contain toxins picked up from the pond bottom.
