Right now these fish have no predation and an almost unlimited supply of forage. I'm curious why I'm catching a few BG that are this skinny. I've gotten stockers from a few different places and I'm not sure if it could just be bad genetics?

It's not often that I catch these fish, but when I do I typically remove them from the pond. Am I doing myself any favors here?

I do have fish that are doing well though, so it's not the entire pond. Here's the only example I have a picture of.
