The SUBIPEDIA has the requirement to take up topics from diving and the organisms in the sea, seriously researched and well-founded something closer.
So the question whether fish fart is not a joke from SUBIPEDIA, but meant seriously.
Admittedly, I can't help but not only point out some serious things about farting.
So the statement: Loud farts do not stink, quietly however terribly.
Or, two homosexuals stroll through stores in search of new clothes. One of them clearly lets off a fart. Says the other; Oh love is in the air.
But now the serious answer: Yes, fish also fart.
But before we get into it, some fart lessons.
The correct term is flatuence, or flatulence as a noun. It is derived from the Latin flatus which means wind, flatulence.
Flatulence refers to the increased development of gases (e.g. methane, carbon dioxide, hydrogen sulphide and other fermentation or digestion gases) in the stomach and/or intestine, after which rectal escape (flatus) of intestinal gases occurs.
During the digestive process in humans, which can take up to 42 hours, intestinal gases are produced. Most of it diffuses into the bloodstream and is exhaled through the lungs. The actual flatulence is an excess of gas of about 0.5 to 1.5 liters per day, which escapes just by farting. Some people have the ability to modulate the pitch of the downward winds by specifically tensing the intestinal sphincter muscle. The most famous of these artistic farts, who used to perform at fairs and carnivals, was the Frenchman Joseph Pujol, who also performed under the stage name Le Pétomane (from French le pet 'the fart') at the Moulin Rouge in Paris in the 1890s.

So not only people fart, but flatulating is not unknown in the animal world. The two biologists Nick Caruso from the Virginia Polytechnic Institute in Blacksburg and Dani Rabaiotti from University College in London have intensively studied the subject and have written a book about it.
In it, they write that some species of herring have developed farting to the point of communicating with it. The herrings swallow air at the water surface, store it in the swim bladder and can release the gas specifically through the anal tract. Farting noises with a very high frequency develop, as if "humans would press air by their loosely one on top of the other lying lips", describe the authors the process. These high frequencies are easily perceived by herrings. The more animals in the flock, the more often they let a fart. Predatory fish cannot hear the sounds.
Other sea creatures use the ability to fart to stabilize their position in the water. The sand tiger shark, for example, sinks to the bottom when it is not actively swimming. To get more buoyancy, it therefore swallows air and stores it in its stomach. If he now wants to rest in the depth again, the shark lets the gas escape through his anus, but not as loudly as the herrings do.
