Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. When taken out of the water, gills (the respiratory organs of fishes) collapse due to which the fishes will not get oxygen further and later on this is the reason for why they die when taken out of the water.
Though some fish can breathe on land taking oxygen from air, most of the fish, when taken out of water, suffocate and die. This is because gill arches of fish collapse, when taken out of water, leaving the blood vessels no longer exposed to oxygen in air.It is the structure of gills that helps fish respire inside water. It cannot breathe through the atmospheric oxygen and hence the fishes die when taken out of the water.
