Disclosed herein are stackable cages for holding oysters, modular cages for holding oysters, floating platforms for deploying and retrieving oyster cages from a long line, and floats adapted to engage a plurality of oyster long lines and from which one or more oyster cages may depend.

Disclosed is a deep sea fish culture life support system. The deep sea fish culture life support system comprises a mother ship, a plurality of net cage groups and a master console, and the system further comprises an automatic feeding system, fixed positioning piles, flexible conveying pipes, rigid conveying pipes and feeding devices. By adopting the automatic feeding system, feed is timely supplied to deep sea fish according to the quantity, the fixed positioning piles are arranged at the two ends of the conveying pipes, the wind wave resistance and the water flow impact resistance are improved, the conveying pipes are laid underwater, the influence of large wind waves and severe sea conditions on feed conveying is avoided, and the safety of deep sea fish culture is effectively guaranteed.

Techniques and systems for robotic aquaculture are described. In one embodiment, for example, a mariculture system may include an aquatic animal containment system operative to hold a population of aquatic animals, the aquatic animal containment system comprising an enclosed hull having a receptacle configured to receive a mechanical core, the mechanical core configured to store at least one sub-system to implement at least one function of mariculture system, and a position management system operative to maintain the enclosed hull at a depth below a surface of a body of water. Other embodiments are described.

An offshore wind-solar-aquaculture integrated floater is provided, including vertical-axis wind turbine systems, solar photovoltaic panels, and a cube aquaculture cage. Four vertical-axis wind turbine systems are respectively rigidly connected to four corners of the cage; solar photovoltaic panels and a living and working quarter are located on cage deck; and side frames of the cage are equipped with tensile nets, the bottom frame of cage is equipped with a bottom net, and columns of the cage are equipped with lifting rails. This floater has good stability, sea-keeping performance and high strength. Utilizations of offshore wind and solar energy above the cage are high and they complement each other in power generation. This disclosure manages to exploit ocean resources to an unprecedentedly large extent, while resolving the issue of combing power generation with marine aquaculture in moderate and deep seas.

A system for cultivating a large quantity of oysters is disclosed herein. The system includes a device that can be placed either on the seabed or the surface of a water environment. The device may be placed at either location and may also be placed further offshore and still be safe from extreme weather conditions. As a result, the benefits of each location are implemented into the system. The system includes an oyster cultivating device including a rectangular frame holding various crates with multiple internal baffles or dividers, and an attached buoyant member for keeping the cultivating frame at or near the surface of the water. The crates are placed such that they fill the volume within the rectangular frame. A buoyant member is then placed on the top end of the rectangular frame. The system provides increased agitation capabilities for oysters to provide a larger and rounder cultivated oyster.
