Hypophthalmichthys molitrix (Valenciennes in Cuvier and Valenciennes, 1844) (ITIS)
Silver carp
Eastern Asia (NAS Database)
1973 (NAS Database)
Imported for aquaculture and for phytoplankton control (NAS Database)
Has the potential to cause enormous damage to native species because it feeds on plankton required by larval fish and native mussels. Is a potential competitor with adults of some native fishes, for instance, gizzard shad, that also rely on plankton for food (NAS Database)

The governors of Illinois and Michigan today agreed to work jointly to protect the Great Lakes from invasive Asian carp species. Gov. Gretchen Whitmer and Gov. JB Pritzker today announced an intergovernmental agreement between the Illinois Department of Natural Resources (IDNR) and the Michigan Department of Natural Resources (MDNR) which allows Illinois to use up to $8 million in funds appropriated in 2018 by the Michigan Legislature to support the pre-construction engineering and design (PED) phase of the Brandon Road Ecosystem Project. Further strengthening the path forward, the State of Illinois also signed a separate PED agreement with the U.S. Army Corps of Engineers for the initial Brandon Road design. The state will serve as the non-federal sponsor, agreeing to help fund design of a portion of the project and to further advance full project design efforts to approximately 30 percent completion.
The Brandon Road Lock and Dam in the Chicago Area Waterway System near Joliet, Illinois, is a critical pinch point for keeping bighead, silver and black carp – the invasive Asian carp species of greatest concern – out of the Great Lakes. The Brandon Road project would install layered technologies including an electric barrier, underwater sound, an air bubble curtain and a flushing lock in a newly engineered channel designed to prevent invasive carp movement while allowing barge passage.

New research by NOAA and partners finds that two species of invasive Asian carp -- the bighead carp and silver carp, collectively known as bigheaded carps -- could be capable of establishing populations in Saginaw Bay, Lake Huron and affecting the health of ecologically and economically important fish species such as yellow perch. The research, appearing online in the journal Biological Invasions, is based on a new model that simulates interactions between the bigheaded carps and a range of fish species, including walleye, yellow perch, and groups lower on the food web over a time period of 50 years. Over 180 non-indigenous aquatic species have already become established in the Great Lakes, with a handful of these producing substantial negative impacts. While bigheaded carps are established in watersheds near the Great Lakes, they have not yet become established in the Great Lakes.

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. The plan’s development was funded by the Great Lakes Restoration Initiative through the Asian Carp Regional Coordinating Committee. The final report can be downloaded here (PDF | 5.6 MB).
