FOCA believes that everyone in Ontario, particularly those on the ‘front lines’ along the Great Lakes shorelines, should be on the lookout to prevent the spread of Asian Carps, including Bighead Carp, Silver Carp, Grass Carp and Black Carp.
upcoming FOCA Lunch-and-Learn webinar:
Wednesday, September 22, 2021 at 12:00pm – Protecting our Great Lakes from Asian Carps
Would you be able to identify an Asian Carp if you saw one? Join FOCA and our partners at Fisheries and Oceans Canada for a one hour “lunch-and-learn” webinar to learn about the threat posed by Grass Carp, Silver Carp, Black Carp and Bighead Carp, and also how to ID carp, and how to report sightings. Everyone on the Great Lakes can be the first line of defence against these invaders. Join us to learn how to help.
Registration for the webinar is required: Click here to register for the webinar.

What you can do to prevent spreading these invaders:
One of the most effective ways for members of the public to assist in this vital effort is simply to share this information with your friends, family and colleagues. The more people who appreciate the costs and dangers posed by this potential invasion, the more motivated people will be to take an active part in defending Canadian waterways from the threat.
If you are a boater or a fisher: make sure your activities never offer a free ride to an invasive plant, fish or animal via your boat bilge or your bait buckets. Many public docks offer information to boaters and other travelers about invasive species and specific local concerns, but every individual must be vigilant.
If you are a lake association representative on the “front lines” (i.e., along the Great Lakes shorelines): consider posting signs at public boat launches warning of the dangers of transporting invasive species, and share this article in your next newsletter or e-news, or at local marinas on a notice board.
If you or anyone you know trades in live fishes: either for food, for pets or in aquaculture (pond) management, make sure you and they observe all regulations governing banned species and ask for expert help if there is any question about the identity of a particular fish.
If you think you have found an aquatic invasive species:
- Do not return it to the water.
- Take photos.
- Note the exact location (GPS coordinates), the observation date and identifying features
- Report it immediately by phone, using the Ontario Federation of Anglers and Hunters’ Invading Species Hotline at 1-800-563-7711, or online through the EddMapS web-based mapping system: eddmaps.org

April 2021 – as reported by the U.S. National Wildlife Federation, a recent study published by the North American Journal of Fisheries Management models the impacts that Asian carps could have on the food webs of the Great Lakes. Computer modelling predicts impacts of bighead carp on Lake Erie, in particular. Read more online here. (the graph at the side is part of Supporting Information document #3 on the American Fisheries Society posting)
Summer 2020: A study by Gertzen et al. (2017) showed that Walleye would be one of many native species irreversibly impacted by the establishment of Grass Carp in our waters.
Summer 2020: Did you know Yellow Perch is at risk of being out-competed by the invasive Grass Carp? A study by Gertzen et al. (2017) showed that Yellow Perch populations would experience declines if Grass Carp were to become established.
Summer 2020: Birds are integral to Great Lakes coastal wetland ecosystems. Grass Carp threaten species like the Canvasback and other waterbirds by destroying wetland habitat and competing for aquatic vegetation as a food source. Learn how to identify Grass Carp and report any suspected sightings to www.eddmaps.org/ontario or by calling the Invading Species Hotline at 1-800-563-7711!

What else can you do?
1) Make your own Cottage Action Plan, to help prevent the spread of invasive species in Ontario cottage country.
2) Write a letter to the Minister of Fisheries and Oceans and the Minister of the Environment to request immediate action to stop this invasive fish from entering the Great Lakes. Call on Prime Minister Trudeau to request that the Trump administration ensures that the short term efforts to prevent an invasion do not fail, and to stress that the U.S. must establish permanent ecological separation between the Mississippi and Great Lakes basins. With information from U.S. Environmental Protection Agency and Ontario Federation of Anglers and Hunters.
What are invasive carps?
Of the many species known as Asian carp, the Bighead and Silver carp, averaging 3 feet long and weighing 60 pounds, pose the greatest threat to the Great Lakes. They are avid filter feeders and can eat up to 20 percent of their body weight in plankton per day. Plankton is the food that most aquatic species rely on; therefore carp have the potential to displace native fish and other species. The Silver carp are slightly smaller but have been known to cause injury to boaters as they jump out of the water when disturbed.

How did they get here?
The invasive carps were imported into North America in the 1970s to be used in southern United States aquaculture operations. Flooding allowed the fish to escape in to the Mississippi and Illinois rivers in the early 1990s and they have been advancing towards the Great Lakes ever since.
What is being done to protect the Great Lakes?
Almost a decade ago, the U.S. Army Corps of Engineers, the U.S. EPA, the State of Illinois, the International Joint Commission, the Great Lakes Fishery Commission, and the U.S. Fish and Wildlife Service began working together to erect and maintain an underwater electric barrier between the carp and Lake Michigan. There are now 3 electric barriers in the Chicago waterway to assist in protecting Lake Michigan from carp introduction. There has also been a 1,500 foot fish barrier fence installed at Eagle Marsh, near Fort Wayne, Indiana, to block advancement of Asian carp into Lake Erie.
The U.S. Army Corps completed DNA monitoring to identify the location of invasive carp in the Chicago canal and found that they are as close as one mile from the barrier. With support from the Obama administration, the U.S. Army Corps of Engineers are working on a 4 year study to determine how to keep the carp out of the Great Lakes. The study is under attack by many environmental groups saying that they need to work more urgently to solve the problem.
The Great Lakes St Lawrence Cities Initiative and the Great Lakes Commission have raised funds to go ahead with their own study to come up with a plan to determine how to re-establish the natural separation between Lake Michigan and the Mississippi basin.
What risk do invasive carps pose to Ontario Lakes?
If these invasive carps are able to enter the Great Lakes and establish a population, they will have detrimental effects on commercial and sport fishing industries, recreational boating, and tourism across Ontario. They consume an enormous amount of food that other aquatic species rely on, therefore displacing native fish and other species.
What is Ontario doing?
The Department of Fisheries and Oceans has committed $400, 000 towards the development of a risk assessment, coordinated along with the US Great Lakes Fishery Commission. This assessment would identify vulnerable tributaries that are at risk of carp invasion and determine techniques for prevention of the introduction of carp into the Great Lakes.
Also, the Ontario MNR is developing a rapid response plan for the introduction of carp.

2014 – The invasive Asian carp are now closer than ever to the last barrier of defence between the infested Mississippi and Illinois Rivers and the Great Lakes. A series of three electric barriers on the Chicago Sanitary and Ship Canal is all that keeps the Asian carp out of the Great Lakes and it is feared that a heavy rain could flood the Des Plaines River, allowing the carp to breach the barrier. Environmental and conservation groups have been urging the Illinois and Obama administration to take action by closing the shipping locks. This has set into motion a study, by the U.S. Army Corps of Engineers, to be completed over the next 4 years. The Chicago barge and tour boat companies argue that closing the locks would have detrimental effects on their businesses.
