I live about 20 miles from Havana Il. This is where Nat. Geo and others film their specials on Asian Carp. They have ruined the Illinois River for any recreational boating. It is dangerous to fish and you really need to stay on alert when running a boat there. I got hit in the head by a 10lb silver a few years ago and it really rang my bell. I have gone to fishing lakes rather than the river because of them. I now drive 40 to 80 miles each way to fish instead of 20 miles. A friend of mine was the president of the Il. comercial fishermen and told me that with the asians making up aprox. 90% of the bio mass of the river that commercial fishermen could reduce that to 5% if the money were there to make it profitable. It requires heaver nets, and closer processing plants also. It's a shame that the Government didn't care until the ultra rich at Lake Michigan in Chicago became worried and even now it might and probably is to late.
