Ever go fishing with someone and have them tell you to quit talking or you will scare the fish away? It is not a myth. Fish can hear in a way. Although they do not have ears like us or other animals, they have what is called a system of lateral lines that run the length of their body on both sides. If you look closely you will actually be able to see these lines on some fish.
These lateral lines pick up movement in the water, water pressure changes and vibrations in the water. Depending on the type of fish this can cause fright and cause the fish to scatter, it can cause aggressiveness and cause a fish to attack or the fish might do nothing at all. Some fish become curious with distant noises and will seek out what is making the noise.
There is a species of fish called Asian carp that are particularly sensitive to noise. So much so that when a boat goes through the water these fish start jumping up out of the water and cause such a frenzy that it then causes other nearby Asian carp to do the same. As fun as it may be to watch this reaction by the fish, it is also very dangerous. Some of these carp get as large as 60 pounds. And when one of these fish hit a skier, nearby swimmer or anyone in the water it can cause major harm to the person. See the following related link above for a you tube video.
Yes fish do hear. So should one be singing at the top of their lungs? Probably not, but perhaps a soft serenade might help with the right type of fish.
