The swim bladder allows a fish to be neutrally buoyant, so it does not have to continuously swim to keep itself from sinking to the bottom or floating to the top. All it needs to do if the water changes density is to adjust the amount of gas in the swim bladder.

Do humans have swim bladder?

All fish have swim bladders. The bladder is what enables them to maintain buoyancy in the water. Without it, they would have to constantly swim up, much like birds have to fly up in the air. It is too much work to constantly swim up, so using a swim bladder, fish do not have to exert as much effort, and preserve energy.
