A closed recirculating aquaculture system (CRAS) using oxygenated ultra fine bubbles

In traditional recirculation aquaculture (RAS), the environmental condition of rearing tank can be controlled in a facility, therefore the system has advantages that it is less susceptible to external factors such as red tides, fish diseases, heavy weather, and it is also high yielding. However, traditional RAS also has disadvantages of high initial costs, high running costs, and thus low profitability.
For RAS, attempts to reduce costs while maintaining productivity have been made for a long time.
Ultra fine bubbles that are making innovations in various fields, has been found to be a key to solve the problem.

Now, we will introduce the innovative system that we have evolved.
