Most fish sink to the bottom of their habitats when they die but they become more buoyant as the process of decomposition takes over. Immediately after death, most fish are slightly denser than water. When a fish dies, it sinks to a depth of about 1/2 to 1 inch (3 to 5 millimeters) below the surface of the water.
If the fish is still alive at the time of death, the body will sink further, but it will not sink as far as it would if it had been dead for a longer period of time. A fish that has been alive for several days or even weeks at a time may still be able to float on its back, although it may not have the buoyancy it once had.
