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 else can I help you with?
How do they maintain buoyancy?
fish maintain buoyancy usind a organ near there gills wich fills with oxygen and keeps the fish afloat
In what ways are fish bladders and buoyancy compensator vests similar?
as they fill or release air it will control where you are in the water. It is a lot harder for a fish, the fish have to get the air from their blood stream because they do not have lungs. Taking in air is harder because it is via their blood and they cannot release the air as fast as buoyancy compensator vests. Include all of this information and you should do fine. :3 your welcome btw
What causes a Betta fish to have buoyancy issues?
stress?
Do fish have buoyancy?
No they cant really control gravity anyway...
Why does a fish have neutral buoyancy?
A fish has neutral buoyancy to maintain its position in the water column without sinking or floating to the surface. This allows the fish to conserve energy by not having to constantly swim to stay at a certain depth. By adjusting its swim bladder or other internal gas pockets, a fish can achieve neutral buoyancy.
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 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.
What makes bony fish float?
Bony fish have a swim bladder that helps them regulate their buoyancy and control their depth in the water. By adjusting the amount of air in the swim bladder, bony fish can increase or decrease their buoyancy, allowing them to float or sink as needed.
Which fish gives an electric current?
eel fish gives current
