In fish like catfish and minnows, the swim bladder is connected to the inner ear by a special set of bones called Weberian ossicles. This physical connection allows a greater range and probably also more sensitive hearing.
The gas-filled swim bladder, which is more compliant to vibration than the fish's body, senses the pressure difference caused by the sound wave; its motion is transferred via bones called the Weberian ossicles to the inner ear.
Catfish and minnows hear better than bass, trout, and other common gamefish because they have Weberian ossicles, bony structures that connect the swim bladder to the inner ear.
