A method, and device for removing sea lice from salmon with use of a salmon herding passage tube, with ultrasound transducers on the periphery thereof, in a number sufficient to provide ultrasound treatment of the salmon being herded therethrough at a normal herding rate and at a sufficiently high enough frequency to kill the sea lice. Salmon are herded therethrough, with the application of ultrasound from the ultrasonic. The method and device also include removal of the lice from a salmon cage or enclosure with feeding fish into an enclosure having ultrasound transducers situated on the inner periphery thereof and providing an attraction such as a white light which attracts noxious parasitic aquatic organisms and applying ultrasound from the electronic transducers within the enclosure.

A modular agriculture system for use underwater. The system comprises a plurality of node elements (101) each including an agricultural unit and a plurality of connection elements (201) for inter-connecting at least some of said nodes to form a mesh-like structure with nodes at the mesh junctions. A significant portion of said connection elements (201) are of low cross section such that when in use and placed underwater they present a low resistance to the action of waves and currents. A plurality of tensioning elements are connected to the mesh-like structure to place the connection elements (201) in tension.

A system of fattening for molluscs having supporting frames with first coupling members for the uprights that make up components and, carriers of the breeding compartments, and second coupling members on the flotation tubes of a moveable platform. The members and the uprights have aligned openings and that are actuated by removable coupling devices allowing the uprights to be attached or uncoupled. A crossbar, with an arrangement of connectors, keeps the components and provides an easily handled module that can be separated from the supporting frame along with the breeding compartments.

Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for controlling an aquaculture feeding system are described. In some implementations, a method includes determining, using a feeding system controller, that a feeding system has transitioned from a first state to a second state, and based on the transition from the first to the second state providing, using the feeding system controller, instructions to a dosing system to set a feed rate of the dosing system, and providing, using the feeding system controller, instructions to a blower operatively coupled to the dosing system to set a flow rate of the blower.

An AI-based system and method for feed monitoring in a land-based fish farm, where the fish farm has a tank containing fish and an effluent pipe that is coupled to the tank where uneaten feed pellets and non-pellet objects flow through the effluent pipe to an exit port. A feed camera is mounted to an effluent pipe for capturing a video feed having images of objects that traverse a field of view of the feed camera when each image is acquired. A special-purpose computer executes a pellet-tracking algorithm that employs a region of interest (ROI) proposal module, an ROI classification module, an ROI tracking module, and a trajectory classification module for at least counting uneaten feed pellets. The computer generates in real time a pellet count based on the pellet trajectories.
