I think anyone who thinks they are not doing well is NUTS, I shot my first bighead in ILL in 1985 in a slough outside of Hardin, ILL, Didnt even know what it was, it took them about 20 years to get really established and take over, they will do the same in the Great Lakes, It will only take longer since it is a bigger body of water, and no amount of Controlled fish kills at $1 million a pop or electric fences or anything else the goverment will find to spend tens of millions of our tax payer dollars on will stop them. They are here to stay!!!!
Our only hope is to arm ever man, woman and child with a bowfishing bow and GO CRAZY.. I think there will be one shot out of the Great Lakes in the next 5 years that will make mine look like a minnow. That is my prediction. I am no Biologist, just a guy who bowfishes alot and is observant to what I see!!!!!!!!!!!!!!!!!!!
