I have a 1/4 acre pond that is overrun with GSF and water snakes. My goal is to convert the pond to a BG only pond for fishing and forage. The 8 year old pond was originally stocked with Coppernose BG and CC, but they appear to be long gone. I've managed to catch or trap several hundred GSF in just a few days, but I don't beleive that I've made a dent in their population, and I'm thinking that a more complete solution might be to apply rotenone. I read several posts about similar GSF problems and some of the possible solutions using LMB. but, I'm thinking LMB and some residual GSF would be a problem in a forage pond.
