Sounds that are created above water typically do not carry enough force to penetrate the surface tension of the water, so talking on the boat or loud noise may not affect fish as much as your fellow anglers may want you to think. Your voice is unlikely to spook or scare fish away.
Can fish hear yes or no?
At first glance, fish don’t appear to have ears, but that doesn’t mean they can’t hear. While there are usually no openings on a fish’s head for sound to enter, they do have inner ears that pick-up sound through their body.
Can fishes hear things?
When sound vibrations pass through a fish, the differences in vibrations between the dense otoliths and the sensory hair cells is detected by the auditory nerves. In some fishes the gas bladder (sometimes called the swim bladder) aids in hearing by transmitting vibrations to the inner ear.
Can fish listen us?
Physical Hearing Adaptations
But regardless of the complexity of adaptations, all fish that we know seem to respond to sound. The lateral line along the side of some fishes is comprised of cilia that are akin to the cilia that line the cochlea of the inner ears of terrestrial vertebrates.
