Dissolved Oxygen. Dissolved oxygen (DO) is the amount of oxygen in water that is available to aquatic organisms. DO is necessary to support fish spawning, growth, and activity. Why do we measure dissolved oxygen? DO is an important indicator of the overall biological health of a waterbody and is required for a waterbody to support aquatic life.

Plants make their own food during the process of photosynthesis. Using light energy, plants can convert water and carbon dioxide into the energy-rich simple sugar glucose. This sugar is the source of food used by most plants and ultimately, by all other consumers. This process also results in the release of oxygen into the air.
