May fish have a little air bag inside them called a swim bladder they add or remove air from this sack so that they achieve neutral buoyancy in the water and thus do not have to exert energy to prevent themselves floating or sinking. If you bring a fish from great depth to the surface very quickly, the fish will not have time to remove air from the swim bladder and it will explode, killing the fish.
When divers collect fish at depth, to keep them alive, they have to stop and let air out of the swim bladders (with a needle) on the way up.

∙ 14y agoit is from the air bladder in there body so that's why wen u bring a fish to surface it
can destroy its buoyancy system

How do they maintain buoyancy?
fish maintain buoyancy usind a organ near there gills wich fills with oxygen and keeps the fish afloat
What causes a Betta fish to have buoyancy issues?
stress?
Do fish have buoyancy?
No they cant really control gravity anyway...
What happens to a fish when it's swim bladder inflates?
The fish gains buoyancy and is able to rise in elevation .
Which parts of a bony fish is used to control buoyancy?
swim bladder
How are fish capable of floating?
they have an organ called a swim bladder. it is a buoyancy device
Why does a fish have neutral buoyancy?
fish need to move through three dimensions and their buoyancy has to adjust so the fish can swim efficiently. they also create different pressures with their fins so they can maintain a certain depth in the water.
Why do fish float in fish tanks?
Fish have an gas-filled, internal swim bladder, whose buoyancy they regulate to keep from sinking or rising in the water.
Why don't fish float back up the water with buoyancy?
They have organs called swim bladders, which balance the fish and keep them from floating.
How is the swim bladder of a fish similar to submarine ballast?
The similarity lies in their use - the control of buoyancy.
What affect provided by water aerobics helps make the exercise beneficial?
Buoyancy
Why do the fish have a swim bladder?
The swim bladder is in animals that need something to help control their buoyancy. Sharks do not have swim bladders because they do not need this.
