The pond is 2-3 acres, a gravel pit, with very spare vegetation currently. It is about 8 years old or so, fairly young. I know there is plenty for them to eat with all the small to medium size bluegills, shiners, fatheads, and gizzard shad. This is why I just don't understand it...? And jakeb it doesn't seem to be effecting any of the the other fish, the crappies, white bass, and bluegills all seem to be normal, actually they are all pretty fat haha
