Another Invasive Species?

Is there another species in Michigan’s Saginaw Bay and Lake Huron?  According to The Great Lakes Environmental Laboratory in Ann Arbor there is.  It is called the Neoergasilus japonicus.  This copepod latches onto the fins of fish in the Great Lakes and eats organic material off their scales.

Although there is no proof, yet, of danger economically or environmentally we still have another new species in our Great Lakes.  The Great Lakes Environmental Laboratory has looked into this new creature.  They said “As long as it doesn’t impact some sort of fishery in the Great Lakes or cause some compounding of water intake, like zebra mussels, it’s probably of no interest for most people.”  As of right now, not much is known on its affect on the fish.

Because of its size the question of how it traveled to Lake Erie has been raised.  A theory to answer this question is that they may have been on pet fish that were dropped into the lake.
