Question

explain the mechanism of floating of fish​

Answer 1

Answer:

the mechanism of fish is very easy

Answer 2

For a fish to be buoyant, or float, it must displace an equal or greater amount of water than its own body mass. The trick is the swim bladder, which is basically like an air-inflated balloon that can expand and contract depending on how much gas is inside. ... This increases the fish's buoyancy and it will float upward.
