Mainstay – Norway
“Our fish tanks are cleaner and healthier thanks to robotic wall cleaning.”
— Facility Manager, Mainstay Aquaculture
Mainstay is a leading aquaculture operator in Norway, managing both indoor and offshore fish tanks for salmon farming. Clean water and stable conditions are crucial to fish health, regulatory compliance, and overall profitability. In high-density aquaculture, waste buildup can reduce oxygen levels and harbor pathogens. Mainstay uses robotic cleaners to maintain tank hygiene without disturbing the fish or halting operations. This technology enables more frequent cleaning cycles, reduces labor costs, and contributes to sustainable aquaculture practices aligned with European environmental standards.
The Challenge
Algae and biofilm on tank walls degrade water quality and fish health. Manual wall scrubbing was inconsistent and time-consuming, disrupting feeding schedules and increasing labor cost.
The Weda Solution
Weda’s Optimizer robot was deployed to automate tank wall cleaning. Its precision movement, suction, and underwater compatibility allowed for consistent maintenance — even between batches.
