Canadian scientists say a small number of Asian carp might be enough to establish a population in the Great Lakes, where they would pose serious threats to other fish and the region's economy.
In a paper published this month, Kim Cuddington of the University of Waterloo says mathematical models suggest there's a 50-50 chance of the invasive carp getting a foothold if just 10 find their way into one of the lakes. If 20 fish slip through, the probability jumps to 75 percent under certain conditions.
Cuddington says the amount of time needed for bighead and silver carp to establish a large population would depend on factors such the fish's age when they spawn.
She says it's unlikely that Asian carp can be kept out of the lakes forever.
Congressman Dave Camp, (R-MI), released the following statement regarding the discovery of live Asian carp in Flatfoot Lake, a land locked lake in northern Illinois which is less than a quarter mile from the Calumet River, which has direct access to Lake Michigan:
"News that a live Asian carp was found dangerously close to Lake Michigan, in Flatfoot Lake, is another reminder that we must find a permanent solution to protect the Great Lakes. Incidents like this underscore the fact the hydrological seperation is the only real way to keep Asian carp from destroying the Great Lakes."
