Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for escape detection and mitigation for aquaculture. In some implementations, a method includes obtaining one or more images that depict one or more fish within an enclosure; generating, as a result of providing the one or more images to multiple detection models, a value that reflects a quantity of fish that are depicted in the images that are likely a member of each different type of fish; detecting an error condition relating to a possible opening of the enclosure based at least on the value; and in response to detecting the error condition relating to the possible opening of the enclosure, initiating one or more mitigation actions relating to the possible opening.

A floating plant (8) comprises a container (1) and a mooring element (2) provided with respective guide elements (10, 13). The guide elements have a mutual complementary shape such that the container (1) and the mooring element (2) may move freely with respect to each other in directions that coincide with the container central axis (CL). A plurality of elongated buoyancy elements (10) are arranged on the container outside and arranged between the container bottom end (17) and the container upper end (18), preferably parallel with the container central axis (CL). The container may be transported to the installation site, floating in the water and stabilized by means of the buoyancy elements (10). The mooring element (2) may be transported to the installation site, either in one piece or on several pieces (2a, 2b), and mounted such that it surrounds a portion of the container. The container is raised and lowered in the body of water by controlling the amount of water in the container.

An aquaculture production and/or transfer system is provided and comprises: at least one floating aquaculture production apparatus on a novel offshore advanced hull system of varying shapes for closed containment method and ecological friendly for sustainable floating farming system (which may be marketed under Eco-Ark™); a station keeping apparatus coupled to the aquaculture production apparatus; a custodian transfer apparatus having a custodian chamber, a chute and a pump, wherein the custodian chamber is fluidly coupled to at least one of the tanks to receive live aquatic animals therefrom, wherein the chute is configured to transfer live aquatic animals to an amalgamated facility.

A modular aquaculture system, and method of using same, deployable in a body of water having a water column, the system including at least one carrier unit defining at least one chamber in which a plurality of containers can be placed. Each container is capable of holding a plurality of organisms to be cultured, and the chamber has at least one chamber inlet for water intake and at least one chamber outlet. The system further includes support structure having sufficient flotation to suspend the at least one carrier unit in the water column. At least one drive unit actively alters a rate of water flow through the at least one chamber and past the containers.

A floating breakwater and wind energy integrated system used for offshore aquaculture. The system contains the wind turbine system, the floating breakwater system, and offshore aquaculture system. The combination of wind turbine, floating breakwater system and offshore aquaculture system makes full use of the floating breakwater, thus decrease the wave load on the floating cage. In addition, the floating breakwater offers a supporting platform to the floating wind turbine, which effectively reduces the costs of the wind turbine. Meanwhile, a power autarkic offshore aquaculture system may be realized by using the electrical energy generated by the turbine. Compared with the simple offshore aquaculture system, the utilization rate of the sea per unit becomes even higher while the costs of the floating wind turbine becomes even lower.

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.
