Ontario officials said in a statement that Asian carp, which is considered as the vanquishers of native aquatic species, has been recently found into Lake Ontario. The marine species is also seen posing a huge ecological threat.

Toronto and Region Conservation Agency officers found the latest grass carp this week when they were out for their routine work at a contained pond at the foot of the Leslie St. Spit. The pond was created about six months ago during construction work, said TRCA spokesperson Elizabeth Oakley.

The second fish was found at another pond nearby. So far it isn't known where the two fish came from, said officials. Both the fish are male and fertile. One of the fish over a meter long and weighing almost 40 pounds, was found Monday.

Becky Cudmore, the Asian carp program manager at the Canada Centre for Inland Waters, said, "No one should panic. I'm not panicking. There is no evidence that there is an invasion. We are dealing with just two fish".

Both the fish are being identified as grass carp, which belong to the Asian carp family. These are native to China and were introduce to US and Europe to tackle aquatic weeds. Since then they have infiltrated waterways throughout the Midwest to such an extent that they are now regarded as a serious threat to the Great Lakes.

Scientists said that if the carp got established in these larger lakes, their constant eating habit will leave nothing for native species to eat. Apart from this commercial and recreational fishing could be affected to a greater extent and the lakes' ecosystems will be devastated.
