The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ in bony fish (but not cartilaginous fish [1]) that functions to modulate buoyancy, and thus allowing the fish to stay at desired water depth without having to maintain lift via swimming, which expends more energy. [2]
[37]: p. 219 In freshwater fish the bladder is a key site of absorption for many major ions [38] in marine fish urine is held in the bladder for extended periods to maximise water absorption. [38] The urinary bladders of fish and tetrapods are thought to be analogous while the former's swim-bladders and latter's lungs are considered homologous.
Isinglass (/ ˈ aɪ z ɪ ŋ ɡ l æ s,-ɡ l ɑː s / EYE-zing-gla(h)ss) is a form of collagen obtained from the dried swim bladders of fish. The English word origin is from the obsolete Dutch huizenblaas – huizen is a kind of sturgeon, and blaas is a bladder, [1] or German Hausenblase, meaning essentially the same. [2]
In Latin, "vesica piscis" literally means "bladder of a fish", reflecting the shape's resemblance to the conjoined dual air bladders (swim bladder) found in most fish. [2] In Italian, the shape's name is mandorla ("almond"). [3] A similar shape in three dimensions is the lemon. The vesica piscis in Euclid's Elements
The totoaba swim bladder is often used for identification more than a morphological description of the fish due to the illegal trade of it. Recent research in 2024 has created a way to identify totoaba swim bladders on-site of legal and illegal trades, that is efficient, convenient, inexpensive, and gives reliable results called real-time ...

Swim bladder disease, also called swim bladder disorder or flipover, is a common ailment in aquarium fish. The swim bladder is an internal gas-filled organ that contributes to the ability of a fish to control its buoyancy , and thus to stay at the current water depth without having to waste energy in swimming. [ 1 ]
Most fish have sensitive receptors that form the lateral line system, which detects gentle currents and vibrations, and senses the motion of nearby fish and prey. [53] Fish sense sounds in a variety of ways, using the lateral line, the swim bladder, and in some species the Weberian apparatus.
