Study Notes
Biofiltration in RAS
- Biofiltration is crucial in Recirculating Aquaculture Systems (RAS) as it breaks down ammonia from fish waste, converting it into harmless nitrate.
Benefits of RAS
- The main benefit of using Recirculating Aquaculture Systems (RAS) is water conservation, as up to 99% of water is reused.
Filtration and Environmental Control in RAS
- Besides biofiltration, other types of filtration (mechanical, chemical, and UV) and environmental control are necessary in RAS to maintain optimal water quality and a healthy environment for fish.
Economic Operation of Commercial RAS
- A key factor for the economic operation of commercial RAS is minimizing energy consumption, as it is a significant cost component.
Research in Intensive Aquaculture
- Researchers are studying the viability of RAS in intensive aquaculture by investigating the effects of high stocking densities on fish growth, water quality, and system efficiency.
