Is it by bubbling over the water which causes air to become trapped in the water or by diffusion of some sort?

There are several factors that affect oxygen contrations in water:
*The potential concentration of oxygen in water decreases as temperature increases, so chilling water will allow more oxygen to dissolve.
* Bacteria and fungi use tremendous amounts of oxygen for respiration, so filtering out microorganisms or other means of purifying water will reduce the oxygen used by microbes.
* Water rapidly becomes saturated with oxygen whenever oxygen and water are in contact with each other. Problem is that water is in direct contact with oxygen only at the water surface, so only a tiny fraction of the water in any waterbody actually is in contact with oxygen at any given time. So, the most efficient way of increasing oxygen concentration is to increase the amount of contact between oxygen and air. There are two ways to do this: bubble air through the water; or agitate or mix the water so that oxygenated air at the water surface is constantly mixed with de-oxygenated air from deeper in the waterbody.
* Diffusion is a very slow process where oxygen from saturated water at the surface slowly diffuses into the less-saturated water below the surface, until the entire waterbody reaches equilibrium. This process depends on brownian motion.

Depending on the scale you want to work with, agitation by bubbling air into the water or pumping the water over a waterfall or fountain can help. Temperature control is also a contribution as cold water will hold more dissolved gasses than warmer water

There are several ways in which this can be done. First plant oxygenating plants, that's those plants that give out oxygen and take in carbon dioxide. 2, you can aerate the water by blowing oxygen directly into the water, 3, agitate the water by churning the water. Hope this has been of some help.

Yes, bubbling air through the water helps more air to dissolve in the water.

For nearly all gases, an increase in temperature reduces the solubility in water

pump air into it which is what you do in a fish tank . or just aggitate it .
