An agricultural amphibious bait feeding boat includes a boat body. A bait feeding device is fixed to one end of the boat body, and a propulsion device is fixed to the other end of the boat body. The boat body includes two foam floating bodies, foam fixing carbon rods, a transverse carbon rod, tube ferrule fixing assemblies, and tee joints. The two foam floating bodies include a left foam floating body and a right foam floating body, the foam fixing carbon rods parallel to each other are respectively arranged above the two foam floating bodies, and the foam floating bodies and the foam fixing carbon rods are fixed through the tube ferrule fixing assemblies The transverse carbon rod is connected to the foam fixing carbon rods through the tee joints, and the left foam floating body and the right foam floating body are fixedly connected to each other.

In one aspect, there is provided a method that includes receiving, by a control system having (i) a first camera configured to obtain an image of a scene, (ii) a winch controller, and (iii) a feeding system configured to deliver a feed to aquaculture, instructions to initiate a calibration of the first camera, determining a calibration state of the first camera, determining a sequence of calibration steps based on the calibration state of the first camera, and executing the sequence of calibration steps to calibrate the first camera.

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.

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.

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.

Generating consensus feeding appetite forecasts include providing a first feeding parameter data set associated with a first feeding parameter to a first feeding appetite forecast model and providing a second feeding parameter data set associated with a second feeding parameter to a second feeding appetite forecast model different from the first forecast model. The first feeding appetite forecast model is adaptively weighted with a first weighting factor relative to a second weighting factor for the second feeding appetite forecast model. An aggregated appetite score based on a combination of the first feeding appetite forecast model using the first weight factor and the second feeding appetite forecast model using the second weight factor. Further, a feeding instruction signal based at least in part on the aggregated appetite score is provided for modifying the operations of a feed control system.

Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for sensor data processing. The method may include the actions of obtaining sensor data regarding aquatic livestock over periods of time, where the sensor data is captured by at least one sensor at different depths, determining, for each of the periods of time, whether the sensor data captured at different depths during the period of time satisfy one or more evaluation criteria, generating an input data set that concatenates representations of the periods of time, providing the input data set to a machine-learning trained model, receiving, as an output from the machine-learning trained model, an indication of an action to be performed for the aquatic livestock, and initiating performance of the action for the aquatic livestock.
