Common Carp

The common carp is native to Europe, but was first stocked into Ohio waters in 1879 as a food fish. This species thrives in a wide variety of conditions and has spread to every county in the state. They are highly tolerant of poor water quality and often become very abundant in areas where few other fish species will live.

Description
The common carp can be easily identified by several features. First, there are two barbels on each side of the mouth. No other species that closely resembles the carp has these barbels. Second, the first dorsal and anal fin spines are serrated. Most carp are bronze-gold to golden yellow on the sides and yellowish white on the belly. Partially scaled or scaleless individuals are frequently caught by fishermen: these are known as "half-scaled," "mirror" or "leather" carp.

Habitat and Habits
Carp prefer warm lakes, streams, ponds and sloughs with a lot of organic matter. They do not multiply readily in clear, cold water. They are tolerant of very poor water quality. They root around on the bottom while feeding often uprooting vegetation and making the water very turbid (muddy).

Reproduction and Care of the Young
Spawning begins in late April and continues into June. Large females lay between 100,000 and 500,000 eggs in vegetation with water depths between one and four feet. Young carp remain in these vegetated areas until they are three to four inches in length and eat primarily small crustaceans.
