A method of feeding an aquaculture of an aquatic animal species of interest is provided. The method comprising providing the aquaculture with an aquaculture feed comprising a sub-optimal dose of protein and an effective amount of butyric acid or salt thereof, the effective amount facilitating reducing feed conversion ratio (FCR). Also provided are feed compositions for aquaculturing.

The present invention discloses a recirculating aquaculture system (RAS) and method for shrimp culture through SBR wastewater treatment. The RAS includes a control cabinet, culture tanks, a clean water tank, a clean water filling pipeline, a drainage pipeline, a buried activated sludge tank and a solid-liquid separation mechanism. The solid-liquid separation mechanism comprises a sludge pump, an input pipe, a plate and frame type filter press and a liquid output pipe. An input end of the sludge pump is immersed in sewage of the buried activated sludge tank; and a clean water output end of the plate and frame type filter press is connected with the buried activated sludge tank through the liquid output pipe.

A smart aquaculture method is provided for an aquaculture system including a breeding pool, a feeding machine and a camera disposed in the breeding pool. The method includes: taking an underwater image by the camera; calculating a feed remaining amount according to the underwater image; and controlling the feeding machine according to the feed remaining amount to dispense feed to the breeding pool.

A system includes a housing; a water tank positioned within the housing, wherein an inside of the water tank is sealed to prevent contact between material forming the water tank and water within the water tank; a water movement subsystem causing water to circulate within the water tank, including a baffle extending along the center of the water tank dividing the water tank into a circular raceway, and a pump causing water to circulate; an aeration subsystem maintaining an oxygenation level suitable for crustaceans to live within the water tank; a temperature control subsystem maintaining a water temperature suitable for crustaceans to live within the water tank; a water quality monitoring subsystem monitoring a water quality parameter of water within the water tank; a feeding subsystem configured to dispense food into the water tank; a biofloc removal subsystem configured to remove biofloc from the water tank; and a control system.
