摘要:
A floating structure and method for obtaining same. The structure includes a first plurality of tubes and a second plurality of tubes. The second plurality of tubes are inserted into the first plurality of tubes to extend through the upper portion of same, and both sets of tubes are welded together. The ends of the tubes of the first plurality of tubes are closed in order to be used as flotation tanks when the floating structure is fitted out for such use. The method concerns locking the first plurality of tubes in place on the frame, with pairs of holes in each of the first plurality of tubes being aligned, and a corresponding tube of the second plurality of tubes being inserted through each pair of aligned holes by force. Each of the connection portions or parts contained in the tubes are welded on the periphery of the holes.

A buoyancy element is for constructing a modular buoyancy system for a circularly shaped net cage. The buoyancy element includes a cage side, an opposite straight long side, and coupling sides between the cage side and the straight long side. The cage side is curved, following the periphery of the net cage.

A fish lighting system has an input interface (10) which receives instructions corresponding to a desired fish behavioral and/or physiological response (12). This is converted into a lighting control signal (RGB, t) for driving a lighting arrangement (18), with the intensity and color of the output from the lighting arrangement selected to obtain the desired fish behavioral and/or physiological response.
摘要:
A method for taking fish up from a body of water comprising the steps of providing a duct (14) having a lower open end below the water surface and an upper open end arranged at a floating working platform (5) above sea level; introducing water into the duct (14) from the upper open end to give a water stream from the upper open end of the duct to the lower open end of the duct; and allowing the fish to swim up in the duct against the water stream therein. The incoming water is directed to flow into the duct, and the fish is separated from the flowing by means of a grating (16) inclining upwards from the top end of the duct to a separation plate (17) arranged above the water level in the duct. A device for taking up fish, using the mentioned method is also described.

An aquaculture net (1) comprises wires that form sidewalls (2) and a bottom (3) of the net (1). The sidewalls (2) form a perimeter for the aquaculture net (1). The aquaculture net (1) further comprises a frame (4) fitting inside the perimeter and leaving a gap between the frame (4) and the perimeter. The frame (4) has a removable auxiliary net (5) inside the frame. The frame (4) is movable up and down inside the perimeter. The frame (4) is provided with bristles or brushes (6) pointing outwards the frame and bridging the gap between the frame (4) and the perimeter.

A net, in particular for protection, safety, water-rearing or architectural purposes, is braided together from individual helically curved longitudinal elements (3) to form a braided structure. Individual longitudinal elements (3) curved into a cylinder or screw shape are twisted one inside the other with adjacent ones and compressed such that the braided structure is in more or less planar sheet-like form and the longitudinal elements (3) here each form more or less rectilinear limbs (8a, 8b; 9a, 9b) and curves (10a, 10b; 11a, 11b) therebetween. The curves (10a, 10b; 11a, 1b) between elongate limbs (8a, 8b; 9a, 9b) are inflected in kink form. This gives a net design with unexpectedly high strength values.

A method for constructing a cage body of a tapered cage assembled in a rigid-flexible manner includes steps as follows. A cage body of a tapered aquaculture cage is assembled by combining a rigid-structure copper alloy stretched mesh and a flexible synthetic fiber mesh. Pipe rings mounted on the standard component of the synthetic fiber mesh are mated in a staggered manner with plugging rings on the standard component of the copper alloy stretched mesh, and high-performance synthetic fiber rope is rove through the pipe rings and the plugging rings; in this way, the connection is completed. The cage effectively improves the cage resilience under the ocean current condition, avoids mesh sheet deformation or corner breakage, enhances the water exchange capability in and out of the cage body of the gravity cage, and effectively improves the growth environment for the fishes farmed in the cage body.
摘要:
A finfish aquaculture containment pen having a plurality of panels that when joined together form the majority of the exterior surface of the containment pen. The panels each comprise tension-bearing mesh material forming the exterior surface of the containment pen, a plurality of compression-bearing struts extending along the boundaries between panels, wherein the mesh material is attached to the struts along the lengths of the struts, and a plurality of hubs at which a plurality of struts and the corners of a plurality of panels abut each other. The panels can form a polyhedral structure. The mesh can comprise coated wire mesh. The struts can be curved members with convex curvature.
摘要:
An integrated multi-trophic aquaculture system (multico) for a primary species, preferably a carnivorous marine species with high market value, secondary, preferably an omnivorous species of medium market value and tertiary species, preferably a detrivorous species with high market value, combined with an unfolding system for the primary species to an open semi-intensive or extensive system, the multico system for the primary species is an intensive closed or semi-closed system. The secondary species is stocked in an intensive closed or semi-closed system, while the tertiary species is stocked in a semi-intensive or closed extensive or semi-closed system. The multico system of the primary species is in communication with the system of the secondary species, while the system of the secondary species is in communication with the system of the tertiary species.
