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.
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.
Thanks to a unique set of bones known as weberian ossicles, which connect their inner ear to that resonator of sound, the air bladder, catfish possess a hearing range far greater than that of other common gamefish.
