Michigan DNR Bulletin - Know the Difference: Invasive versus common carp

The Michigan DNR published an informative bulletin titled "Know the Difference: Invasive versus common carp" on 6/30/16 featuring some very insightful information about "naturalized" carp aka "common carp" and "invasive" aka "big head", "silver", "black" or "grass" carp.

From the article:

Because they have been widely distributed and their demand as a food source has diminished, common carp sometimes are referred to as a nuisance species. However, they are not considered invasive in Michigan.

I enjoyed the article because it helps explain some critical differences between what is actually "invasive" and what is not.
