White Perch: The Culprit Behind the Great Lakes Mystery

How did the White Perch most likely find its way into the Great Lakes?

Introduced through canals or put in by governments.

Answer:

Trapped in a ship's ballast or a water tank

The White Perch, a fish native to Atlantic coastal regions, has caused quite a stir in the Great Lakes as an invasive species. It has been feeding on native species and is believed to be the reason behind the decline of the Great Lakes walleye fish populations.

So, how did the White Perch make its way into the Great Lakes? The most likely scenario is that it was trapped in a ship's ballast or a water tank during transportation. This would explain its sudden appearance in the Great Lakes despite being native to a completely different region.

It is highly unlikely that the fish could have made the journey through any other waterways on its own. But with the help of transportation via ship's ballast or water tanks, the fish could have been brought over in a faster and more efficient manner.
