An animal feed dispenser includes a control module and a feed dispensing module. The control module includes a detection member and an electronic control card. The detection member is suitable for generating a detection signal when the feed dispenser is located close to an enclosure containing animals. The feed dispensing module includes a feed dispensing orifice and an actuator. The electronic control card is configured to receive the detection signal and, as a function of the detection signal, to transmit an activation signal to the actuator and the actuator is configured to trigger a flow of feed through the dispensing orifice when the activation signal is received.

An automatic food feeder for aquatic breeding comprises a bottom plate; the lower side of the bottom plate is provided with a driving mechanism, and the driving mechanism comprises four groups of rotating shafts located on the lower side of the bottom plate; gears are sleeved on the outer sides of the two groups of rotating shafts, and a conveyor belt is connected between the two groups of gears; a plurality of groups of meshing teeth matched with the gears are uniformly provided on the inner side of the conveyor belt, and a plurality of groups of electric telescopic push blocks are uniformly arranged on the outer side of the conveyor belt; a placing rack is connected on the upper side of the bottom plate, and a control box is connected on the front part of the lower side of the placing rack.

The present invention relates to a method of raising fish in a recirculated aquaculture system which includes a fish holding unit in fluid communication with a water supply, the fish holding unit containing a volume of water defining a water depth, and having an osmotic concentration, an oxygen concentration, a temperature, and a pH. The method includes providing a flow of non-recirculated water to the water supply, the non-recirculated water being different from the water in the fish holding unit with respect to the osmotic concentration, the oxygen concentration, the CO2 concentration, the N2 concentration, the NH4+ concentration, the temperature and/or the pH, providing feed pellets, adding the feed pellets to the non-recirculated water and hydraulically transporting the feed pellets to the fish holding unit. The invention also relates to a RAS facility.

Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for the automated feeding of fish. In some implementations, a corresponding method may include obtaining meal configuration data including one or more parameters indicating a meal plan for feeding farmed fish; executing the meal plan based on the meal configuration data; receiving sensor data from one or more sensors during execution of the meal plan; and adjusting the execution of the meal plan based on the sensor data from the one or more sensors.
