How do swim bladder help to move fish?

The swim bladder is a gas-filled organ that helps fish maintain buoyancy and stabilize their position in the water column. By adjusting the amount of gas in the swim bladder, fish can rise or sink without expending much energy, allowing for efficient movement. This buoyancy control enables fish to navigate different depths and conserve energy while swimming. Additionally, it assists in maintaining balance and orientation while the fish is in motion.
