Fish, like us, need oxygen to live. However they have gills to taken oxygen from water, whereas we have lungs to take oxygen from the air. Therefore, when fish get taken out of the water, as they don't have lungs they have no way to take in oxygen, so they die.
Oxygen is taken in by the lungs through the process of inhalation. When you breathe in, air containing oxygen enters the lungs through the trachea and bronchial tubes, eventually reaching the alveoli where oxygen is absorbed into the bloodstream.
