The invention relates to a solution that enables optimized regulation of feeding rates in aquaculture systems. The invention involves a feed detector shaped as a pipe segment that can be directly installed as a pipe socket in an outlet pipe of an aquaculture system. The feed detector comprises a pipe segment, radiation means and detection means.

A method of monocular depth estimation includes receiving a plurality of monocular images corresponding to images of fish within a marine enclosure and further receiving acoustic data synchronized in time relative to the plurality of images. The plurality of images and the acoustic data are provided to a convolutional neural network (CNN) for training a monocular depth model. The monocular depth model is trained to generate, based on the received plurality of monocular images and the acoustic data, a distance-from-feeder estimate of a vertical biomass center of fish within the marine enclosure.

A method of surface splash scoring includes receiving, at an electronic device, a set of camera frames corresponding to images of a water surface. The electronic device processes the set of camera frames with a trained machine learning model to generate one or more quantifications associated with fish activity proximate the water surface. In some embodiments, a surface splash score is computed that represents an appetite level anticipated to be exhibited for a first time period. Subsequently, the electronic device generates an output indicative of the surface splash score.

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.

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.
