Subject adjusted to avoid any chance people think the article is about
Common Carp. The Bighead and Silver Carp made their way up the
Illinois River and are supposedly blocked by barriers. What if the
adult Bigheads spawn nearby and the tiny fry get through the barriers?
In addition, how can boats get through the canals in Chicago WITHOUT
any chance of fish getting through?

It's inevitable the Bighead and Silver Carp will get into the Great
Lakes and consume a high percentage of the plankton that form the food
chain. Of course there's almost no such plankton remaining because the
zebra mussels made the lakes almost lifeless. Irresponsible
publications such as In-Fisherman have claimed zebra mussels are a good
thing because they made the water in Lake Erie clearer; this shows
In-Fisherman is worthless.
