The advantages of a closed loop aquaculture system are:

① It can significantly increase the stocking density and productivity per unit of water body;

② Can shorten the breeding cycle;

③ Can reduce the bait coefficient;

④ Significant savings in labor, water sources, and production sites, especially suitable near large cities with limited water sources, high land prices, and severe water pollution;

⑤ Flexible and adaptable, with a wide range of applications, convenient production management, and easy harvesting;

⑥ Unrestricted by natural temperature conditions, continuous production throughout the year, achieving multi crop cultivation and balanced marketing.
