Our focus on energy-efficient technology for optimal water flow, combined with innovative filtration and pumping solutions that ensure sufficient capacity with low energy consumption, gives our customers both biological benefits and economic value.
Hexacage can produce fish on an industrial scale with a density of at least 60kg/m3 and with an energy consumption between 1 and 1.5 kWt per kilogram of salmon, using oxygenation and filter.
We are setting a new standard for closed aquaculture at sea by combining the control and design of land-based systems with the efficiency of sea-based operations. Hexacage is engineered like a modern land-based facility, equipped with technology that ensures optimal water quality and production capacity.
Water quality and exchange time are critical to the economics of any closed-containment system. By distributing intake water through nozzles across the entire water column, combined with a central column for drainage, we ensure an optimal environment for the fish — enabling ideal production conditions throughout the full tank volume.
The raise-and-lower function of the tank facilitates efficient cleaning and disinfection routines after each production cycle, similar to what’s standard in land-based systems.
Hexacage is a modular, scalable system offering flexible solutions tailored to different operational models, production cycles, and stages of company growth.
The system is built around a hexagonal module that can operate independently or be connected with additional units to form large-scale production platforms — with up to six producing modules.
Customized barge solutions are also available for feed storage and sludge management, with optional operations and accommodation facilities as needed.
By connecting three modules into a single unit, Hexacage enables one of the most efficient post-smolt production solutions on the market. In collaboration with various aquaculture operators and economists, we have calculated a potential annual output of nearly 7,500 tons of 1-kg post-smolt.
Each module is certified for wave heights up to Hs 4.3 and can be installed wherever environmental conditions or logistics make the most sense — without needing to compromise due to weather exposure.
Our solutions have been thoroughly tested at SINTEF Ocean laboratories in Trondheim.
In any production cycle, fish grading can be economically beneficial, and harvesting often occurs in several batches.
These processes typically involve crowding and fish pumps — both of which can cause stress.
Hexacage offers a unique system for crowding and moving fish, with minimal stress and no use of fish pumps. Contact us to learn more.
