Forever Chemicals in Freshwater Fish

My understanding is that bio-accumulating chemicals tend to concentrate in the fatty tissues and filleting and trimming belly fat does lessen exposure.

I have also read smaller younger fish have less contaminates

Which makes sense because they have been exposed to the environment for a shorter period of time. They have ingested a smaller amount of contaminates during that time.

It's also true that "bottom feeders" tend to accumulate more of the heavy metals (PCB, mercury, chromium, etc.) ... like some Carp, Catfish, Drum, etc.

I have heard that as well. I want my catfish pretty young.
