Fishes respire with the help of their gills. Gills are richly supplied with blood capillaries and can readily absorb the oxygen dissolved in water. The water contains some dissolved oxygen in it. When the water enters the fish through its mouth, the dissolved oxygen is taken inside and carbon dioxide is given out through the gills. In this way, the fishes breathe in water. When fishes are taken out of water, the supply of oxygen to the fishes is cut as the fishes cannot absorb and breathe using the oxygen present in the atmosphere. Hence, they die after some time.
