    What a weird thing discuss, too bad it isn't the weirdest one I've heard.

    Sorry, I don't have the answer. All I know is that "gas" that comes out of the ass is produced from the bacteria in the intestines. The "gas" is a by-product from when the bacteria eats whatever that is undigested by the body.

    I'm assumimg fishes have intestines.

    Ask a marine biologist.

    Probably not as much as land-based animals:
    http://en.wikipedia.org/wiki/Fish#ExcretionAs with many aquatic animals, most fish release their nitrogenous wastes as ammonia. Some of the wastes diffuse through the gills.


    Most gas in the intestines is due to swallowed air. Not much of that in water, I would think, unless they actually surface.
    There are some interesting examples of fish farting here:

    Fish actually do fart specifically herrings

    I learned this a few years back that they use it as a communication tool.

    here are some info

    Yes, some Cories do it all day long. The go up to the surface for air, then quickly shoot out a fart bubble.

    Hmm actually I remember that from my own fish tank, these guys indeed do that.

    Man, my brain feels enriched today icon_biggrin.gif

    I think that gas in us and cows is caused by bacteria in the gut that are digesting celulose that we can't otherwise digest. And these bacteria enter us after birth. Which makes me wonder how they could be introduced to fish.

    It would be a flaw to me for fish to have evolved farting on their own or not be able to stop whatever would cause them to fart. Because that gas would cause a serious change in bouyancy that could cause the fish to rise to the surface (exposing them to air-bourne preditors, if nothing else).

    So, I'm guessing, but I'm guessing no.


    cellulose actually gets passed through humans. its the shorted chain oligosaccachirides that provide fuel and energy for the bacteria in our gut , and thus produce gas. these then get turned into short chain fatty acids that we can use to some extent for energy. also cows do have a beta amylase enzyme that digest the the beta bonds in cellulose. this is if i remember my carbs lipids and protein metabolism class correctly

    Unreal...

    Obviously, the men of RJ are the experts on this subject.

    While we're at it, can anybody tell me how fast my hair grows?

    Measure each strand of hair you have today. Then measure the length in two weeks. Subtract and average the length differences and divide by 14 days. icon_wink.gif

    Some experts say that the digestive gasses of fish are consolidated with their food waste and expelled in gelatinous tubes which fish then eat.

    But, fish have been known to emit bubbles due to an excess intake of air. For instance the sand tiger shark purposefully gulps air into its stomach at the surface then farts it out at the other end so it sinks to its desired depth.

    If you consider farting to be the by-product of digestion (gases) expelled solely through the rear-end, then no most fish don’t fart (with the exception of herring and sand sharks).

    Fish fart.

    Happy to provide resolution.

    so when fish do the one cheek sneak, do they lift a fin and let one go?

    *facepalm*

    Of course they can, but not very often. Metabolism of organic matter always produces CO2 as a major product. If the concentration of gas in the intestine exceeds it's solubility in the fluid, then bubbles will form. If the rate of fluid flow through the intestine is great enough to remove gas before the solubility limit is reached, bubbles will not form. Low temperatures tend to increase solubility and decrease metabolic rates.

    Sometimes my fish swim around with little klingon bubbles... so embarrassing.
