About Us

At Subfarm we are passionate about bringing the salmon back to its natural habitat – the fresh, crisp and roaring ocean.

We are setting a new standard for open ocean aquaculture, fish welfare and sustainability.

The management team and the board of directors at SubFarm have extensive managerial and technical experience from industrial development, and have a proven track record from entrepreneurial business and finance.

The Current Challenges in Salmon Farming

The Technology

Single point moored, winch operated, submerged cage technology.

Optimal Temperature

Keeps the salmon at the optimal temperature level and ocean conditions, away from sea lice and toxic algae.

Easy Operations

Allows fish transfer and harvesting operations in rough weather conditions, without surfacing the cage.

Reliability

Easy to disconnect for maintenance of cage on-shore. Cage structural elements built and assembled locally. Scalable development to reduce risk.

Areas of Application

The advantage of using a submersible cage compared to traditional floating frames is to significantly decrease the risk of biomass loss and, consequently, the potential for high economic loss. Furthermore, recent factual evidence on sea-lice attack protection and algae blooms points to prevention with a deeper net installation. This extends the application of submersible cages.

Existing Farms

Avoid exposure to sea lice and toxic algaes by free positioning of cage in the water column. No need for surfacing of cage during fish load-out.

Exposed Areas

Expansion of production into more exposed areas within existing production regions. No need for large, complex steel structures.

Service Image

Open Ocean

Open new production regions offshore with favourable sub-surface temperatures and close to the consumer markets.

Co-locating with offshore wind

Combination-farming improves spatial use and reduces areal conflicts. SubFarm’s distributed cage system allows for integrated aquaculture farms inside perimeter of offshore wind farms.
