    Especially since you can get a portable pressure swing adsorption oxygen concentrator like you see advertised on TV for people who need supplemental O2.

Draw that down to total vacuum, and the gas in the bubble is about 41% O2. So the bubble, under some reasonable assumptions is somewhat O2 enriched air.

    At a total vacuum you cannot have water at roomtempertur as a liquid It will be steam
    Boilingpoint of water lowers with lower pressure So the gas you see is watervapor Steam mostly

    Methane is only (very) slightly soluble in water. My guess would be dissolved oxygen and nitrogen from air. You'd also get water vapor at a low enough pressure but that would condense pretty quickly.

    Eh, fish farts. Not MY cup of tea, but, to each their own.
