Common Carp

Common Carp

Common Carp have naturalized into nearly all Iowa waters and are now one of the most abundant and widely distributed fish in the state, found in virtually every stream, river, man-made lake, and natural lake unless specifically removed.

Originally introduced from Europe over a century ago.

Physical Characteristics:
  • Common Carp in Iowa are large, robust minnows that can weigh up to 50 pounds or more, with adults commonly reaching substantial sizes.
  • They feature compressed bodies with soft, fleshy mouths that open ventrally, distinctive serrated spinous rays on dorsal and anal fins, and visible barbels extending from the upper jaw.
  • Three varieties exist in Iowa: fully scaled (most common), leather carp (scaleless), and mirror carp (few large scales).

What to know

Habitat Distribution

  • They thrive in low gradient, warm waters of lakes, reservoirs, and soft-bottomed, weedy pools of streams, adapting well to turbid waters and pollution from agricultural runoff.
  • They prefer warm water with standing or sluggish flow, abundant soft organic matter on the bottom.

Key Locations

  • Productive locations include Pool 19, Pool 18, Pool 16, and Pool 17 on the Mississippi River, Red Rock Reservoir, Coralville Reservoir, Saylorville Reservoir, Clear Lake, Storm Lake, West and East Okoboji Lakes, Lake Macbride, Spirit Lake, and numerous other lakes and river systems throughout Iowa.

Specific Spots

  • Focus on areas with soft bottoms, submerged structure like logs and brush piles, shallow vegetated zones, and areas with organic runoff.

Common Carp are omnivorous feeders consuming aquatic insects, crustaceans, small mollusks, tender roots and shoots of aquatic plants, often 'rooting up' large quantities of vegetation and silt while foraging.
