Common Carp

Common Carp

Common Carp are a non-native invasive species introduced to Wisconsin waters in the 1880s-1890s by the U. S. Fish Commission, originally intended as a food fish.

These European natives are now widespread throughout Wisconsin's lakes, rivers, and streams, present in virtually all major water bodies.

In Wisconsin, carp have become so prolific that in some lakes they comprise 99% of the fish biomass, causing significant ecological damage by stirring up sediments, destroying vegetation, and creating algae blooms.

Scientific Name: Cyprinus carpio

Physical Characteristics:
  • Adult carp are light gold to dark brown with reddish fins, featuring distinctive barbels (whiskers) on each side of their mouth and large golden-brown scales.
  • They can reach impressive sizes - up to 5 feet in length and 80 pounds, though most range 14-35 inches and 4-32 pounds.
