Fishes swim because of presence of air bladder.

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.

Because air sacs and spongy bones are absent in fishes and swim and air bladder help them to float.

Air sacs are found in the lungs which is the alveoli and swim bladder is for buoyancy in water.

Because of air bladder and swim bladder these enable the fish to float on the surface of the water.

Yeah this is true I accept this answer. Because of swim bladder and air bladder only. Fishes do not sink.

That is true, air sacs helps the fish to float on water.

Yes, I also think in water the swim bladder helps to swim and air bladder contains air to float a fish in water.

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.
