Catfish Smell

Some catfish smell bad but can also cause serious health problems if eaten. Catfish, also known as “garden eels,” are a type of fish that live in slow-moving water near the bottom of lakes and ponds.

Catfish get smelly because of the bacteria that they carry. The bacteria create an ammonia smell, which is why catfish can smell bad. There’s a skin disease that produces sulfur-containing compounds.
