ADPH has an online guide that lists fish consumption advisories in the state located here:

No mention of PFAS, though. Problem is, PFAS can be everywhere -- air, soil, water, etc. Think about where all that stuff has been historically applied: textiles, cooking/kitchen items, household products -- basically everywhere.
I'm not a big conspiracy theorist, and I have eaten plenty freshwater fish, but bottom line is, we've got to take better care of our waterways. These persistent chemicals/compounds are a problem. And look, I'd much rather eat some freshwater Alabama fish than something farmed in Thailand or China or wherever.
