RAS Water Quality Awareness
NAFC Course Code: AQ65
This training course provides a theoretical introduction to the fundamentals of monitoring and maintaining water quality in Recirculating Aquaculture Systems (RAS).
Topics covered include:
- 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.
This is a half-day course delivered at the NAFC Marine Centre, or elsewhere by arrangement.
