Fish let out natural gases. That gas is oxygen but they do not let out methane or any other gases.
To let out gases.
Same as all the other fish. Water over gills, gills pull out needed gases and dispose of waste gases.

To let gases that build up, out of your body
Open/close to let in air/fuel mix and let out exhaust gases
yes it gases them
Like all fish- through their gills.
They both have a a stomata that let in and out gases.
Open/close intake & exhaust ports. let in fuel. let out gases after combustion.
The gases in air will, to some degree, dissolve in water. Let's consider one example. We know that fish need oxygen to live, and they get this from the water that passes over their gills. If there was no dissolved oxygen in the water, the fish would die.
