SetterG - It seems the YP are telling you there are still fair numbers present and that you are not a very successful perch angler. You will have to spend some time this year sharpening your skills for catching YP. Keep trying & learning you will learn the technique.
I totally agree! The seven I caught yesterday were with a little imitation minnow. I've got my fly rod up here. I'd really like to catch them on a fly. About the only solution I see for that would be with a imitation floating fish food, and fish when the feeder goes off.
Where can I find a fly that looks like Optima?
Any other ways I can catch perch with a fly rod? Any issues with catching perch while the feeder goes off? (I don't want to scare them off feed.)
San Juan worm in correct color would match Optimal. Or, this would be an easy fly to tie if you go this route: I'd match foam strip [to ensure it floats] and dub to correct color and wrap them on nymph hook shank. That's how I'd address matching the Optimal "hatch".
