How Do Fish Produce Sound?
Fish generate sounds through various mechanisms, primarily involving the manipulation of their swim bladder or the friction generated when their fins attach to their body. Much like crickets produce sound by rubbing their legs together, fish use these methods to communicate and navigate their underwater environments. The swim bladder, an air-filled sac, plays a pivotal role in sound production as it can be rapidly oscillated to create distinct noises. Additionally, when fish move their fins against the bones where they connect to their bodies, this friction can produce audible sounds. These sound-producing mechanisms are vital for communication, locating prey, and maintaining social interactions among various fish species. (Source: March 7, 2018)
How Do Fish React To Sound?
How do fish react to sound? Fish exhibit remarkable sensitivity to low-frequency vibrations, typically those below 10 Hertz. When confronted with a sufficiently intense sound source, fish tend to react by swiftly moving away from it. This instinctual behavior is rooted in their evolutionary survival mechanisms, as low-frequency sounds often signal the presence of an impending predator. Hence, fish have evolved to perceive and respond to such auditory cues as a means of avoiding potential threats in their aquatic environments.

The otolithic end organs are involved in hearing in all fishes, through the detection of particle motion (Popper and Hawkins, 2018). In some fishes, sensitivity is also shown to sound pressure through the coupling of a gas-filled body (e.g., the swim bladder) to the inner ear (e.g., Poggendorf, 1952).Fish make sounds by oscillating their swim bladder, or by rubbing the bones where their fins attach to the body, similar to how crickets make sound by rubbing their legs, she said.Fish is extremely sensitive to low-frequency vibrations, below some 10s of Herz. If the sound source is sufficiently intense, fish usually respond by swimming away from the source. The reason for this is probably that low frequency sounds usually indicates an approaching predator.
