Yes. It's the larger fish like shark & swordfish that contain large amounts of mercury that u should avoid.
The mayo clinic says catfish is safe. There are healthier fish that are higher in omega-3s but catfish is still a safe fish to eat. I've read omega-3s are great for brain development so I try to eat as much sockeye salmon as possible while pregnant...which is only about once a week since it's so expensive...plus I've been feeding it to my daughter since she was 6 months, she's two now and loves fish.

You can have salmon once a week. Make sure it is completely cooked. Don't go sushi place.
I eat it. Just try to make sure it's smaller catfish bc they eat other fish and build up mercury. Or try an alternative fish... not sure of one though.
If i recall correctly my doctor told me to stay away from eating that.
