How do fish change depth in water?
A fish controls its depth by increasing or decreasing the amount of air in its swim bladder. When a fish has more air in the swim bladder, it is more bouyant and rises to the surface ,but when it lets out the air and the swim bladder fills with water, it becomes less bouyant so the fish sinks.
What is air fill bladder which prevents fish from sinking when it stops?
It is called the "Swim Bladder".

How does a bony fish use the swim bladder?
Helps maintain Fish buoyancy ( from further down in the water or to surface) The swim bladder can fill by gulping air at the surface, this enables the fish to float or empty by loosing air from the swim bladder through a pneumatic duct (a pneumatic duct is an internal gas filled organ) connected to the oesophagus, this enables the fish to sink.
What gives a fish its buoyancy?
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.
What are some uses of a bladder in a fish?
To urinate, if you mean the urinary bladder. If you mean the swim bladder, it is to be able to change its depth in the water. It has a way to vent air from the gills to the swim bladder, and from the swim bladder to the digestive tract. So the fish would inflate the bladder to be able to rise and deflate the bladder to go lower.
