Great Lakes Sea Grant Network Releases Comprehensive Report on Asian Carp, Prevention

12:08 pm, Thu November 2, 2017 – The document includes information on a range of carp-related topics, from life history to ecosystem impacts

Columbus The Great Lakes Sea Grant Network has released a comprehensive and coordinated outreach and education report on Asian carp in the region. The document includes information on carp life history, movement and behavior, monitoring, control, ecosystem impacts and gaps in current knowledge that need to be addressed further.

“These invasive fish have the potential to devastate the Great Lakes’ ecosystem,” said Tory Gabriel, Ohio Sea Grant fisheries educator and Extension program leader. “The report informs Great Lakes stakeholders about the danger posed by four species of Asian carps, and what is being done to keep these fish from invading the system.”

The report includes listings of already prepared education and outreach materials from the Mississippi and Great Lakes basins that managers and other groups can use to educate stakeholders on the invasive fish. A survey of state and federal agency experts summarizes current research on Asian carp, and identifies information still needed to most effectively control their spread. Additionally, a list of state speakers allows local interest groups to reach out to experts near them to educate members directly.

“This comprehensive report gives us three pieces of valuable information, which support our fight against Asian carps as a threat to Great Lakes” said Debbie Lee, director of NOAA’s Great Lakes Environmental Research Laboratory in Ann Arbor, Michigan, and that agency’s lead member of the Asian Carp Regional Coordinating Committee. “It provides a clear picture of the overall potential impact of an Asian carp invasion of the lakes, it identifies specific gaps in our understanding of that impact, and lastly, it contains a large inventory of outreach and education materials that scientists, managers, and educators can use to communicate the Asian carp threat to the general public.”

The plan’s development was funded by the Great Lakes Restoration Initiative (GLRI) through the Asian Carp Regional Coordinating Committee. The final report can be downloaded at

Asian carp is the collective name used for four non-native species of carp from Asia currently found in North America. The fish known for jumping out of the water and possibly injuring boaters is predominantly silver carp, which was brought to the United States for aquaculture along with bighead carp, grass carp and black carp. The species most commonly of concern in the Great Lakes are silver carp and bighead carp, which are moving up the Illinois River towards the Chicago Area Waterways System that connects the river with the Great Lakes.

The primary concern over Asian carp in the Great Lakes is their impact on an already stressed food web. Silver carp and bighead carp compete with small forage fish and young sport fish for food and could negatively impact the lakes’ fishing industry. Grass carp eat the vegetation that provides prime wetland habitat and black carp feed on mollusks like native mussels, many of which are endangered. At the same time, Asian carp have few natural predators because they quickly outgrow native predator species, often within just a year. In parts of the Illinois River, silver carp and bighead carp make up more than 90% of the fish biomass, essentially outcompeting all native species for food and habitat.

The Great Lakes Sea Grant Network is a collaboration of Sea Grant programs along the Great Lakes, which includes Illinois-Indiana Sea Grant, Lake Champlain Sea Grant, Michigan Sea Grant, Minnesota Sea Grant, New York Sea Grant, Ohio Sea Grant, Pennsylvania Sea Grant and Wisconsin Sea Grant.
