The land-based recirculating water laboratory is a recirculating water ecological breeding experiment project designed in a standard container. Through functional modules such as water quality measurement and control, temperature control and oxygenation, water disinfection and purification, collection of fish feces and residual pellets, and data platform, the reusability of water is guaranteed to the maximum extent, making fish farming healthier and more environmentally friendly, and finally realizing automatic operation of equipment to achieve the goal of green production, environmental protection, energy saving, and risk control.
