I really appreciate the responses and taking your time to post on this. I'll dive right into the topic again. Im glad retenone was brought up. I consider myself a conservationists. My father is a conservationists, and technically was soil conservationists for the NRCS for 40 years. I Grew up trapping, hunting, and of course fishing...but I still was hesitant to talk about the usage of chemical with dad as well as you guys, but I guess its not that bad of thing, it's just the thought of it I wasnt used to. Dealing with solely green sunfish I get it and I know you guys do but still. Ultimately, I did use chemical to kill as many green sunfish as possible. I was thinking once I saw gsf surfacing and dieing, the whole pond would be wiped clean of gsf as the entire perimeter was coated with chem and amount was factored in. It didnt completely wipenthem out, but I'd say it ridded of a lot. Hard to give a percentage of how many, but after a couple weeks you couldn't see any gsf in the shallows anymore like you could. So im saying at least half were knocked out which will hopefully help. I was worried about them, little aggresive, big mouthed predators they are. I was surfing the internet for the best fish trap today actually, its always a popular item in question as to what's the best to use, and if anyone has had experience with a successful perch trap I'd love to hear. Also, all my perch were added to the pond well after chemical and all that. I also added many pounds of fhm before perch were added. Kind of all of the place here, but trying to get this response out. I know the gsf are still present because out of about 15 of the perch caught on rod and reel when I went back in early spring I caught 4 gsf, none big, all small.
