When a fish dies does it float or sink? Most fish are slightly denser than water, so sink immediately after death. However, like a drowned human, they become more buoyant over time as bacterial decomposition produces gases inside the body. Usually, enough gas builds up in body cavities to make the corpse float, like an inflated balloon.
How long after a fish dies Does it float? After the fish dies there is no more DO being ingested and the air in the bladder starts to dissipate, causing the fish to sink to the bottom. After a few days, the internal organs of the dead fish decompose and a gas is formed. This gas causes the fish to once again float.
Do fish always float when they are dead? It should also be noted that fish don’t necessarily always float when they die. For example, if a fish dies with little to no air in its swim bladder, the act of dying doesn’t magically make this bladder expand to increase buoyancy. In these cases, the fish will often sink, at which point decomposition will begin.
