I like Walt's idea. I wanted to go the Tiger Muskie route for eliminating Gizzard Shad in our 10 acre lake. Instead we went the "total fish kill" route on July 30, and will have to have another fish kill in October as the largest Carp survived and spawned. Now it looks as though we have a Carp only infested lake. We did harvest lots of LM Bass and Bluegill out before the fish kill and put them in other ponds and lakes.
The Tiger Muskie route sure would be a lot less expensive than the rotenone option of starting over, and worth a try if it is your own water body unlike mine which is shared in a sub division.

I subscribe too, but tried and failed at the fish logo.
