Try as we may, we can't put the Genie back in the bottle. Think about it, a little over 100 years ago when the Europeans first introduced the common carp tothe Americanwaters, I'm sure they never could have imagined that over time that particular fish would come to inhabit almost all waters from farm ponds to the Great Lakes and everything in between. Only Mother Nature will eventually determine this fish's domain in 50 years. You might slow it down but you can't stop it and so is it really worth millions of taxpayer dollars in order to delay the inevitable. I'm not sure that it is.
