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.

Mooring systems and methods are provided. One system may include at least one object partially or fully submerged in a body of water. The system may also include a semi-rigid outer ring that is adrift or moored to at least one sea anchor or to the sea floor by at least one mooring line. At least one object may be connected or tethered by bridle lines to the semi-rigid outer ring to form an array.

The present invention relates to a method, a system and an apparatus for treating food items. Such method and device may, for instance, be used to cool down food items, bleed freshly slaughtered fish and treat live fish against parasites. The device and method of the present invention further uses temperature differences and agitation to tread food items. A method for reducing or eliminating sea lice from salmon fish, said method comprising: a) transporting the salmon fish from a reservoir and the feeding salmon fish in liquid into the tubing of a first pumping device, said liquid being at a temperature from +15 to +28° C., b) transporting the salmon fish in liquid through the tubing of the pumping device at a first set time period for treatment in said liquid, c) feeding the salmon fish out of the first pumping device, d) separating the liquid from the salmon fish, and e) transporting the salmon fish back to the reservoir, wherein the liquid media from the pumping device is redirected after separation from the salmon fish in step d) through a heat exchange element back into the pumping device for continued treatment of further salmon fish, and wherein the temperature difference between the liquid used in steps b) and the reservoir is more than 15° C.

An oyster farming device comprising containers configured to contain oysters and linked to at least one ballast. The device comprises a horizontal pivot axis, parallel to a longitudinal direction, and at least two rigid arms that ling the pivot axis and the ballast, parallel to the longitudinal direction, such that the filling or emptying of the ballast causes the arm to rotate about the pivot axis and results in the emergence and rolling of the oysters in the containers.

A pen system is for farming aquatic organisms. The pen system has an outer surrounding rigid structure and an internal, closed enclosure. The outer surrounding rigid structure forms an upper portion and a lower portion. The pen system further has: an internal surrounding connecting element, the closed enclosure being attached to the connecting element; and a heave-compensation system having a plurality of fluid-filled cylinders, each fluid-filled cylinder being hingedly attached, in a first end portion, to the connecting element, and being hingedly attached, in a second end portion, to the inside of the rigid structure.

A floating mooring structure including a framework formed by a plurality of equidistant parallel tubes, a second plurality of tubes extending through the first plurality tubes and a third plurality of tubes extending through the first plurality spaced from and below the second plurality of tubes. The structure also includes peripheral berthing beams and additional flotation tanks with shock-absorbing fenders and with vent tubes that help stabilize the structure and serve as mooring posts for vessels.
