SubFarmSubmersible Aquaculture Cage System for Salmon Farming

SHARE

SubFarm is revolutionizing the aquaculture industry by introducing advanced solutions to the pressing challenges faced by salmon farming. Their Submersible Aquaculture Cage System is designed to enhance fish welfare and productivity by operating in the open ocean, providing salmon with conditions akin to their natural habitat. The system effectively mitigates common industry issues such as sea lice infestation and toxic algae exposure by submerging the farm below problematic surface layers, thus improving fish health and reducing operational costs. With a single-point mooring and winch-operated design, SubFarm’s technology ensures optimal temperature levels for salmon and facilitates operations even in rough weather, all while minimizing visual pollution. The cage's structural elements are built locally to enhance reliability and ease of maintenance, providing a scalable solution that supports sustainable aquaculture practices. Additionally, the system’s compatibility with offshore wind farms presents a unique opportunity for co-located aquaculture, enhancing spatial efficiency and reducing environmental impact. By tackling transportation concerns, SubFarm positions itself as a leader in sustainable, innovative aquaculture capabilities, bringing production closer to consumer markets around the globe.

Most popular related searches

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.

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.

Open Ocean

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