I've had threadfins stocked the last 2 springs............and until a few days ago I assumed they were an expensive snack. I was paddling about the pond just before dusk ,when I sighted what appaered to be a school of shad on the surface. They appeared to be just mouthing the surface like little dippling..........can anyone confirm this is how thread fins feed and should I expect their population to flurish now that they have survived and reproduced despite the 14-16 inch LMB ?
