  1. Control of Common Carp in the Heron Lake Watershed, Minnesota

    Verrill, Donovan D.

    Common carp Cyprinus carpio were radiotracked during the winter of two years in North (83 7 hectares) and South (13 60 hectares) Heron Lakes, Minnesota to monitor survival and behavior in these shallow (maximum depth 1. 5 m), turbid lakes. Winterkill conditions killed four of six radiotagged common …

  5. Biotic Impacts in Shallow Water Bodies of South Dakota Resulting From Common Carp Invasion

    Letvin, Alexander Paul

    Common carp Cyprinus carpio (hereafter referred to as carp) are one of the most common freshwater fish invaders worldwide that are known to have adverse ecological effects. They are generalists that possess a suite of life history traits that make them very efficient at invading new water bodies …

    Hennen, Matthew J.

    The common carp Cyprinus carpio is a ubiquitous invasive species naturalized to aquatic systems throughout North America. Following their intentional introduction in the United States in the late 1800’s, the common carp’s commercial and recreational value declined during the 20th century. They are …

  14. Field and laboratory studies suggest that recruitment of the invasive common carp is controlled by native fish in Stable Lakes of the Upper Mississippi Basin.

    Silbernagel, Justin J.2011

    Recent studies have shown that recruitment of the common carp in many lakes of the Upper Mississippi Basin is limited to areas that experience an ecological disturbance that alters the fish community. It has been hypothesized that recruitment of carp is limited by native predatory fish and that …
