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.

An aquarium having an adjustable lighting system for enhancing the display of fluorescent objects, such as fluorescent fish, contained within the aquarium under various external lighting conditions, such as a dark room or a brightly lit room. The aquarium comprises a tank and a plurality of light sources. Each light source emits light at a different wavelength spectrum which is selected to enhance the display of the fluorescent object under each type of external lighting condition. An electronic control is provided to control the operation of the plurality of light sources such that each light source may be selectively turned on/off based on the external lighting condition, or chronological criteria, to provide the best viewing experience.

Apparatus and methods for aquaculture feeding are provided and, in particular, apparatus and methods for mixing dry feed with water to form a flowable feed composition and distributing the flowable feed composition in a fish or other aquaculture tank at multiple locations in the form of discrete extrudates. The apparatus and methods can be used to adjust properties of the extrudates to correspond to the conditions of fish in the tank and/or conditions in the tank.

A sensor positioning system, includes an actuation server for communicating with components of the sensor positioning system. The sensor positioning system additionally includes a first actuation system and a second actuation system, wherein each actuation system includes a pulley system for maneuvering an underwater sensor system. The sensor positioning system includes a dual point attachment bracket that connects through a first line to the first actuation system and connecting through a second line to the second actuation system. The underwater sensor system is affixed to the first pulley system, the second pulley system, and the dual attachment bracket through the first line and the second line.

An automated system for administering food to laboratory animals housed in aquatic tanks includes a plurality of individual feeding units that independently communicate with a common feed management hub. Each feeding unit includes a rack for holding a collection of aquatic tanks and a wireless robotic feeder configured to move in three dimensions relative to the rack. The robotic feeder precisely meters and delivers liquid and/or dry food to each rack-mounted tank in accordance with user-modifiable feed schedules which are maintained by the feed management hub. To compensate for any adjustments to the particular arrangement of tanks within a feeding unit, the robotic feeder periodically scans the rack for tanks and transmits the scan data back to the feed management hub. Accordingly, the feed management hub ensures that the proper type of food is accurately and timely delivered to each aquatic tank in compliance with the stored feed schedules.
