Ontarians should be vigilant and help to protect the province's lakes and rivers from invasive species, Natural Resources Minister David Ramsay said today.

"Invasive species are a very real environmental and economic threat to the Great Lakes, inland lakes and rivers," said Ramsay. "The public has a key role to play in protecting our natural environment, and recreational and commercial fisheries from these species."

The rudd, an invasive fish, has been found for the first time in an inland Ontario lake.

The rudd was discovered by Toronto and Region Conservation staff during routine fish community assessment in Lake Wilcox, which is located in the headwaters of the East Humber River in Richmond Hill.

A European member of the minnow family, the rudd is believed to be spread through dumping of bait buckets.

Prior to its discovery in Lake Wilcox, it was known to occur in Ontario only in isolated locations within the St. Lawrence River and the lower Great Lakes.

The rudd can cross-breed with the indigenous golden shiner, resulting in hybrid young and a potential loss of the unique genetics of the golden shiner.
