RAS Water Quality Awareness
This half-day course provides a theoretical (classroom-based) introduction to the principles of monitoring and maintaining water quality in Recirculating Aquaculture Systems (RAS).
The course covers a variety of topics, including:
- Background: recirculating compared to flow-through aquaculture systems.
- Fish water quality requirements: oxygen, temperature, pH, salinity, ammonia, nitrite, and nitrate.
- Principals of recirculation systems: nitrifying & denitrifying bacteria, start-up procedures, monitoring, bio-towers, fluidised beds, and filtration.
- Common problems & what to do: crashes, oxygen / carbon dioxide, power cuts, clogging, ozone / UV, chemicals (disinfectants), and antibiotics
- Fish health problems & treatment in recirculation units: ammonia poisoning / brown blood disease, bacterial gill disease, fungus, carbon dioxide, low oxygen, pathogenic bacteria, and heavy metals.
