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.
