There is provided a smart aquaculture grow out system for aquatic species, the system includes a feeder adapted to store aquafeed, the feeder comprising a feed dispensing nozzle, a feed dispenser operable to measure and project aquafeed via the feed dispensing nozzle, and a controller operatively being operable to selectively activate and deactivate the feed dispenser. A set of sensors are operable to acquire sensor data comprising water quality parameters of a pond adjacent to the feeder and images of aquatic species in the pond. A processor receives the sensor data of the grow out system, and determines, based on the sensor data of the grow out system, a metered quantity of aquafeed to provide. The processor transmits a control signal to the controller causing activation of the feed dispenser to measure and project the metered quantity of aquafeed via the feed dispensing nozzle.

The invention provides a process for the production of seafood in a closed-loop multitrophic aquaculture system comprising the steps of: (A) culturing phytoplankton in a medium, wherein said medium is irradiated with light; (B) transferring such cultured phytoplankton to a medium for culturing zooplankton; (C) transferring such cultured zooplankton to a medium for culturing seafood; and (D) transferring a part of the medium of step (C) as nutritient to the medium of step (A), thereby creating a closed loop, wherein steps (A) to (D) are carried out in a closed system, in which free gas exchange with the environment is prevented. The invention further provides an apparatus for carrying out this process.

An aquaculture system (10) comprising growing modules (GM) and liquid treatment modules (LTM). Each growing module is associated via a network of pipes (101, 201, 202) with a respective liquid treatment module to form a pair (161, 162), wherein if liquid flow through a given pair (161, 162) is stopped and left to settle, liquid within the given pair (161, 162) is arranged to balance out to the same level.

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.
