Dark Coloring on Fish

[Jim G]

I have caught several panfish with dark coloring on them. Some all dark, some top half and some bottom half. The majority of the fish caught in the lake do not exhibit this darkened condition. Is because of their age or is it a disease or sickness. Any education on this would be appreciated.

Thanks

Jim that is a new one on me. I have bluegills around here that are almost completely black but they are lighter at the bottom. Never seen that one before.

Do you know what causes them to be dark?
Thanks
