How can swim bladder and air bladder help fishes not to sink in water?

Somashree Banik said: (Sep 28, 2011)  
Swim bladder help fishes to swim in water but air bladder helps to float because it contains air.

Harini said: (Apr 11, 2012)  
Swim blader helps to the fish to swim and the air blader contain air it helps the fish to float in the water.
Then I want to know which fish it is.

Bibhu said: (May 13, 2012)  
Please explain me the answer.

Nahome said: (Jun 9, 2012)  
This is always true. They swim without sink b/c they contain swim bladder and they float freely b/c they involve air in their bladder.

Bibs said: (Jan 15, 2013)  
We can swim without floating our body means underwater.

Pankaj Kumar said: (Mar 6, 2013)  
Swim bladder and air bladder are air filled sacs hence they help to swim fish.

Hari Priya said: (Apr 11, 2013)  
I'm also accept this. Because fishes have a AIR BLADDER. It helps to floats the easily.

B.Jayasree said: (Dec 23, 2013)  
Most of the fishes contain swim bladder and gall bladder. They are used as to float. Due to the presence of air in the bladder they don't sink in water.

Jordann Ishmial said: (May 8, 2014)  
It can't be a swim bladder that helps a fish swim because I doesn't make any sense. The truth is that air sacs and spongy bones help fish to swim and it makes sense.

Romesh Bhagat said: (Nov 10, 2014)  
Fishes swim because of presence of air bladder.

Gabeini Turi said: (Mar 27, 2015)  
Fishes do not sink in water because swim bladder keep the fish on water surface if it is filled with air. But if fishes want to sink to ward the bottom of water they open swim bladder and release air in it. If there is no air in swim bladder the fishes weight increase and the simply sink in water.

Anmol said: (Mar 30, 2015)  
Because air sacs and spongy bones are absent in fishes and swim and air bladder help them to float.

Ayomide said: (Sep 16, 2015)  
Air sacs are found in the lungs which is the alveoli and swim bladder is for buoyancy in water.

Pat said: (Oct 24, 2015)  
Because of air bladder and swim bladder these enable the fish to float on the surface of the water.

Shradha said: (Dec 26, 2015)  
Yeah this is true I accept this answer. Because of swim bladder and air bladder only. Fishes do not sink.

Gladys said: (Dec 31, 2015)  
That is true, air sacs helps the fish to float on water.

Sandeep(Sandy) said: (May 15, 2016)  
Yes, I also think in water the swim bladder helps to swim and air bladder contains air to float a fish in water.

Vijay Shinde said: (May 22, 2016)  
The swim bladder is located in the body cavity and is derived from an out-pocketing of the digestive tube.

It contains gas (usually oxygen) and functions as a hydrostatic, or ballast, organ, enabling the fish to maintain its depth without floating upward or sinking.

Patrick said: (Sep 6, 2016)  
What is the function of an air bladder?

Musavvir Khan said: (Mar 5, 2017)  
What is the role of Swim bladder and air bladder in fishes?

Tell me the accurate answer with correct explanations.

Chetan Sharma said: (Mar 29, 2017)  
I think swim blade help them to swim continue in water and air blade also decrease their density that's why most of fishes don't sink in water.

Deepthi Potu said: (Mar 31, 2017)  
Yeah, How this air bladder and swim bladder help fishes not to sink?

Suhani said: (Dec 12, 2017)  
The swim bladder and air bladder are internal gas-filled organs that contribute 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 sinking or having to waste energy in swimming.

Aaghar Badshah said: (Jan 24, 2018)  
Please explain the answer.

Purnima said: (Apr 27, 2018)  
Please explain the answer in detail.

Swim bladder help fishes to swim in water but air bladder helps to float because it contains air.
