WebFeb 21, 2024 · As you can probably guess, since the swim bladder is the buoyancy organ of a fish, its purpose is to help fish regulate their depth. Yes, some fish simply use their fins to swim up and down in the water column, but this uses quite a bit of energy that fish sometimes just don’t have to spare. WebThe trick is that the swim bladder, which is basically like a balloon filled with air, can expand and contract depending on how much gas is inside. When the swim bladder expands, it will increase in volume and therefore displace more water. This increases the fish's buoyancy and it will float upwards.
The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ that contributes to the ability of many bony fish (but not cartilaginous fish ) to control their buoyancy, and thus to stay at their current water depth without having to expend energy in swimming.
