Habitat: The common carp were initially introduced in Europe in the 1880s and were initially found in Illinois in 1886. They are now naturalized into nearly all Illinois waters. Carp prefer warm lakes, streams, ponds and sloughs with a lot of organic matter. They tend to thrive in poorer water quality.
Feeding and Habits: Carp like to root around on the bottom, uprooting tender roots and shoots of young aquatic vegetation, which makes the water murky. Aquatic insects, crustaceans, and small mollusks make up the bulk of their forage.
Reproduction: Spawning occurs from mid-April through June. Large females will lay their eggs in vegetation with water depths between one and four feet. Splashing carp, often with their backs out of the water, can be observed during the springtime spawn.
