Invasive Carp Threat

A Threat to the environment, the economy and tourism

The spread of invasive species is a significant and immediate threat to the health of waterways and aquatic life throughout the USA.

The Four Species of Invasive Carp

Silver, Bighead, Grass, and Black

Bighead, silver, black and grass carp – previously referred to as Asian carp – have established populations in the Mississippi, Illinois and Ohio rivers. Local, state and federal agencies are therefore working to prevent further expansion that could have catastrophic effects on the Great Lakes.

According to the US Fish and Wildlife Service, invasive carp can establish a population within two years of the first individual arriving. They are highly adaptive and spread at rapid rates, with a mature female capable of producing over a million eggs each yea

Minnesota Recognises More needs to be done

The Minnesota Department of Natural Resources (DNR) has released an updated Invasive Carp Action Plan, developed with inputs from various stakeholders, including researchers and advocates. The plan emphasises integrated pest management strategies, including deterrents at locks and dams, monitoring, fish capture and removal, and coordination with partners. Here’s an overview of their findings.

  • Urgency for Action: The spread of invasive carp in Minnesota waters is not yet severe, offering a critical window to implement preventive measures. The state has recognised the need for immediate action to prevent a potential takeover by invasive carp, highlighting the timeliness for deterrent solutions.
  • Emphasis on Deterrents: A key focus is on the installation of deterrent systems at strategic locations to prevent invasive carp from moving upstream. Lock and Dam 5, located about 10 miles upstream of Winona, has been identified as a critical site where a deterrent could stop 99% of invasive carp from moving upstream.
  • Opportunity FGS: The state’s commitment to exploring the feasibility of deterrents at Lock and Dam 5 and other locations presents a significant opportunity for BAFF manufacturers. The plan acknowledges the need for further design and engineering at these sites, implying potential demand for advanced deterrent technologies.
  • Funding and Advocacy: Despite the recognized need for a deterrent at Lock and Dam 5, the DNR has not committed to pursuing funding for construction in the immediate term. This situation may create advocacy opportunities for FGS to engage with stakeholders and advocate for the prioritization and funding of deterrent projects.
  • Public Support and Awareness: Public meetings and discussions about the invasive carp issue have shown significant community interest and concern. As a manufacturer, engaging with these community discussions and demonstrating the effectiveness of your deterrent solutions can build public support and potentially influence policy and funding decisions.

The Cost of Carp

The economic threat of invasive carp

Invasive carp have no natural predators and consume the resources native fish populations need to survive. Their rapid spread serves to crowd out native species and their impact on freshwater mussels that keep aquatic systems healthy upsets the balance of ecosystems.

These threats go hand in hand with economic challenges and a physical threat to boaters and vessels. The Environmental Protection Agency notes silver carp leaping out of the water have caused injuries to humans that include black eyes, broken bones and concussions.

Recreational fisheries are suffering in many areas as people are discouraged by large volumes of invasive species, which can have a devastating impact on the local economy.

Experts state invasive carp as national problem

“The invasion of these carp species is not a Minnesota problem, or even an Upper Mississippi River problem. This is a national problem that is on the brink of becoming an environmental crisis of tremendous significance.”
