Title: Explain the importance of managing water quality.
Course: Aquaculture Infusion Units (AIU) > Section: Introducing the Aquaculture Industry

Explanation should include

- dissolved gases and oxygen
- aeration
- carbon dioxide (CO2)
- testing
- alkalinity
- clarification
- hardness
- water source disinfection
  - ozone
  - ultraviolet (UV) light

- oxygen enhancement
- nitrogen forms such as
  - ammonia (NH3)
  - ammonium (NH4)
  - nitrite (NO2)
  - nitrate (NO3)
  - nitrogen gas (N2)
  - sulfuric acid (H2SO4)

- phosphorous
- total dissolved solids (dissolved solids and wastes)
- temperature
- salinity and specific gravity
- pH (alkalinity, acidity)
- dissolved oxygen (DO) cycle
- ammonia cycle (N)
- carbon dioxide (CO2) cycle
- pH cycle
- system-specific water management practices (avoid overfeeding, monitor DO, control unwanted organisms, prevent runoff from entering facility, add water to improve quality)
- stress caused by diminished water quality (shock, chronic, acute stress).

Process/Skill Questions:

- Why is it important to consider water quality as a whole rather than as a sum of its various parts?
- How do temperature and salinity affect dissolved oxygen?
