Odd growth on bluegill???

[sp3worker]

I was fishing at my aunt and uncles pond last week and I caught this bluegill with some kind of growth on it's back. I've seen a couple other bluegills with what looks like blisters on their sides as well, this one was the worst. I was thinking maybe it's some kind of parasite? None of the other fish in the pond are like this, just the bluegills. Sorry for the blurry pics.

Ooooooooo!

Maybe the septic tank is too close to the pond? :fishing:

I would send those pics to a wildlife biologist. I would definitely find out whats occurring in the lake.
