When it comes to running a successful and profitable aquaculture farm it is critical to avoid fish loss while maximizing growth and feed efficiency.  There are many factors that can contribute to the successful production of fish and shrimp, however, if you do not have suitable dissolved oxygen in the water, the farm will be guaranteed to fail. Oxygen is as critical to aquatic animals as it is to human life. 

Managing suitable dissolved oxygen levels is accomplished through two processes: aeration and oxygenation. Aeration is the process of mixing ambient air with water. Oxygenation is the process of delivering pure oxygen to water.  While these two technologies deliver oxygen to the water, they are different processes that have their own benefits and drawbacks. This module will cover topics such as oxygen transfer rates, how environmental factors affect oxygen transfer and saturation, differences among aquatic species, oxygen demands of a system, how to design aeration and oxygenation systems, and an overview of the novel technologies the supplier industry has to offer.
