Sounds are vibrations transmitted through the gases, liquids or solids. They are pressure waves that have a frequency and wavelength.
For sounds to be heard, they need to be able to pass from the air to the water. Normal sounds and even shouting are not passed from air to water. The frequency shift is too great. Sound travels 4.3 times as fast in water as in air and so the sound cannot penetrate and is reflected.
"A water–air interface is usually an almost perfect reflector of acoustic waves."
Sound and the water–air interface
Fish do have internal ears for higher frequency vibrations and lateral lines for lower frequency.
What fish do sense through their lateral lines are the vibrations we make when we wade AND the underwater "sounds' we make with wading staffs. The sense the vibrations from us walking on the river bank. These vibrations are transmitted from ground and not the air.
Shout and yell all you want. Fish are deaf to that. If someone tells you the fish can hear that, they are mistaken.
