The Chicago River waterway gets much of the attention as the route Asian carp could use to enter the Great Lakes by way of Lake Michigan.

But Canadian authorities say Lake Ontario is also a vulnerable entry point. The Northumberland News recently reported that Canadian border officials have stopped six truckloads of the voracious eaters in the past two years.

The average truckload contained about 6,000 pounds of the fish which many fear could disrupt the Great Lakes ecosystem. Two of the six cases have been prosecuted, the Ontario publication reported. The most recent resulted in a $60,000 fine.

“The fear is a truckload of live Asian carp could roll off a highway and dump live carp into our waterways, which would be devastating,” John Cooper, a spokesman for the Ontario Ministry of Natural Resources, told the Northumberland News.

The province in 2005 outlawed the sale of Asian carp which are sometimes sold live at fish markets.

The publication reports that Canadian officials recently announced $17.5 million to be used over the next five years to help protect the Great Lakes from the threat.

Update: There are increased signs of Asian carp advancing past the Sanitary/Ship Canal electric barrier.
