RAS Case Studies
RAS
One of the main advantages of a Recirculation Aquaculture System (RAS) is that it maintains a perfect environment with superior water quality at minimum cost. All significant water parameters are monitored online and adjusted accordingly; ensuring optimal fish health and growth.
Together with an optimal environment for fish rearing in tank design and operation, and customized grading and feeding solutions, this is the foundation for predictable aquaculture production and superior harvesting quality for all species.
Essentials of Succesful RAS Farming
1. Filtration：removal of organic matter in the form of settleable solids is the first cleaning step in RAS.
2.Monitoring parameters: a RAS farmer has to make sure that all the important water quality parameters are kept optimal at all times.
3. Feeding strategy: a RAS feed needs to precisely meet the nutritional requirements for optimal and efficient growth.
4.Off flavour control
5.Health management: health management is a critical factor in the profitability of fish farming business, where both experience and expertise are vital.
