In the news: Small number of Asian carp could establish a large Great Lakes population

Posted September 16th, 2013 in Aquatic Invasive Species

Recent research indicates that even a handful of Asian carp, between just ten and twenty fish, could establish an ecologically damaging population in the Great Lakes. 

 From ScienceDaily.com: 

“Published this week in the Biological Invasions journal, research from Professor Kim Cuddington of the Faculty of Science at Waterloo indicates that the probability of Asian carp establishment soars with the introduction of 20 fish into the Great Lakes, under some conditions…
 
‘This species will have a huge impact on the food web,’ says Professor Cuddington. ‘Not only is it a fast-growing fish physically, but the population itself grows very quickly. A female can lay well over a million eggs a year, and with no known predators present in the Great Lakes, the Asian carp could dominate the waters and impact fisheries.’…

Individual fish have already been caught in two of the Great Lakes. The probability of Asian carp establishment changes dramatically if only 10 of the creatures are introduced. With 10 fish, the probability of a population of Asian carp is only 50 per cent, but with 20 fish, it jumps to 75 per cent, under some conditions.”

This February marks a major milestone: 30 years of aquatic invasive species outreach by our team! To celebrate, IISG Director, Stuart Carlton, and Strategic Communication Coordinator, Renie Miles, sat down for a Sea Grant Chat with two key figures in IISG’s AIS history: Pat Charlebois, our assistant director and program leader, who spent over two decades leading our prevention efforts, and Katie O’Reilly, who took over that role in 2022. We discussed the evolution of the invasive species issue in the Great Lakes, the shift toward understanding human behavior, and the creative strategies that make this team so effective.
