Probably correct in adverse effect of the the larger class of fish, won't effect the overall population as they reproduce too fast in MOST lakes. But removing the 2lb. + fish which, Livescope allows those who have learned it to target can not help but hurt that class of fish and I'm already seeing it on my home lakes in Ga. That being said it is not realistic to think there is any way to put that Genie back in the bottle. It's our new reality. IMHO, Scott
