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.

Methods, systems, and apparatus, including computer programs encoded on computer-readable storage media, for automated camera positioning for feeding behavior monitoring. In some implementations, a system obtains an image of a scene, a spatial model that corresponds to a subfeeder, and calibration parameters of a camera, the system determines a size of the subfeeder in the image of the scene, the system selects an updated position of the camera relative to the subfeeder, the system provides the updated position of the camera relative to the subfeeder to a winch controller, and the system moves the camera to the updated position.

A system and method for remote monitoring and command and control of one or many offshore aquafarms is provided. Operators are able to securely access web applications and services hosted in the cloud through which husbandry functions such as feeding fish, cleaning the cage and removing mortalities can be automatically scheduled and executed. Offshore aquafarms relay information, such as environmental sensor data and video feeds back to the cloud to be viewed by the operators.

A method for detecting fish school hunger degree based on feeding behavior includes: detecting a water wave fluctuation driven by the feeding of a fish school using a water surface floating body; controlling a fish feeder by calculating water wave fluctuation intensity. The water wave fluctuation is detected by adopting a detection device associated with the water surface floating body.
