I have caught several fish with the large blotches and spots of black all over them. I have always heard that this is a sign of "health" or a "healthy fish population". Caught a few from Cedar Creek with these spots, as well as one this past Monday (MLK Day, 1/18/2010). The one I caught from Dale Hollow had the spots all over the tail, which you can see in the pictures.

CAN ANYONE GIVE ME A REASONABLE (maybe biological) EXPLANATION ON THIS?

Are they birthmarks in the fish's DNA, or is it some kind of disorder with the fish?
