CLOSED FISH CAGE

HOLDING PEN

POST-SMOLT CAGE SYSTEM

Protection from sea lice & sludge collection.

Aquasafe is a simple and safe closed cage in steel that prevents escape, protects farmed salmon against lice and disease in addition to minimise pollution of the sea and seabed with sludge collection.

This cage is a steel container with closed walls and bottom, without complicated ballast systems. Aquasafe has four stabilizing columns and the draft is adjusted by regulating the amount of water in the cage itself.

Water exchange in the cage can be achieved through abundant water flow in tubes, or the Aquasafe can be equipped with a desired water treatment system. 

The desired draft in normal operation is maintained by the use of overflow on the wastewater and in normal operation the cage itself has a small positive buoyancy. The cage will therefore maintain its draft even in case of an accidental leak to the surrounding bodies of water (inherent safe design).

Holding pen and post-smolt production.

Aquasafe can be built in sizes from 3.000 m3  to 50,000 m3  and is well suited for many areas of application, from post-smolt production to holding pens. Aquasafe is also well suited for farming adult salmon as well as delousing. 

An Aquasafe of 20,000 m3 has a steel weight of approximately 400 tonnes.

Reliable in farming operations.

Aquasafe is equipped with an internal net that fully utilizes the volume of the closed cage. For holding pens that are emptied regularly, this contributes to a well-known, reliable and cost-efficient method of moving farmed salmon to well-boats. The salmon can be moved with the traditional raising of the net and removing the salmon from the top. Alternatively, a flexible hose can be attached to the bottom of the net and the fish moves through it while the net is raised. Moving salmon from the bottom has shown positive effects on welfare because it utilises the salmon’s natural instinct to swim downwards during crowding. Withdrawal at the bottom ensures calmer and less stressed salmon, which has positive effects on fillet quality. This has been confirmed during several rounds of moving salmon from the bottom of the cage during operation of Aquatraz.

Easy access for disinfecting and maintenance.

Aquasafe can be emptied and raised out of water by pumping water out of the cage. A smaller holding pen the cage can then be lifted by crane to gain access to the entire cage for washing and disinfection.

A larger Aquasafe can be lifted completely out of water on site using our patented compressed air-based lifting system. This enables a cost-efficient way to perform washing, disinfecting and maintenance of the cages on site, with no need for heavy lifting vessels. In raised position, the fish cage can easily be towed to a new location.

A larger plant consisting of several Aquasafe in a rigid frame can also be lifted completely out of the water, more about that in the next section below.

Efficient post-smolt production.

Several Aquasafe can be assembled together in a rigid frame constituting a larger closed fish farming system. A farm with several closed cages in a rigid frame can handle more exposed locations than a single closed steel cage. Piping between the various cages makes it easy to sort and move farmed salmon between the cages,  which is central for optimising post-smolt production.

Integrated lifting systems ensures that the cages and the platform can be lifted completely out of water. Providing an easy an cost-efficient access for cleaning, disinfecting and maintenance of the entire fish farming facility on site.

An alternative post-smolt production facility is the Aquantum 12K

Cost-efficient closed fish cage.

Aquasafe is in its simplicity a cost-effective steel cage. Further more, this cage culture technology has a unique patented construction and assembly method. The cage can be produced in modules which are stacked for transport to a location where it can be launched at sea and mounted without the need for special equipment.

The desired draft in normal operation is maintained by the use of overflow on the wastewater and in normal operation the cage itself has a small positive buoyancy. The cage will therefore not change the draft considerably even in case of an accidental leak to the surrounding bodies of water (inherent safe design).

Piping between the various cages makes it easy to sort and move farmed salmon between the cages,  which is central for optimising post-smolt production.

A patented lifting system can be used on such a fish farming system consisting of minimum four cages. This integrated lifting system is a cost-efficient solution to lift one or more cages completely out of water simultaneously, as well as the entire frame. Providing easy access for cleaning, disinfecting and maintenance of the entire fish farming facility on site.

An alternative post-smolt production facility is the Aquantum 12K. This patented system also consists of closed cages assembled in a rigid frame. Here, each cage has its own lifting system and can be lifted independently of each other, while the modular frame easily can be assembled and disassembled.
