The patented 360FishSweep™ fish handling equipment has been developed in collaboration with SalMar Farming and Lerøy Aurora to extract cleaner fish and sick or wounded fish in a highly efficient, predictable and gentle way. In less than a year, our system has removed more than 1 million lumpfish and many thousands of salmon that have suffered from disease or injuries.

We say 360FishSweep™ is the world’s most efficient fish handling equipment. With a very high depletion rate, minimal wear and tear on the crew and efficient operations, we are confident in this claim.

Feel free to contact us for references from customers who have become well acquainted with the system.

The VØA Ring™ is a completely new fish handler tool that we believe most aqua technicians will find highly valuable — both during daily normal operations and when facing moderate biological challenges in the pen. The equipment is a temporary collection net which makes removal of fish more ergonomic, efficient and escape-proof.

The VØA ring™ is a floating collection net that technicians drag around the pen during removal of sick and/or wounded fish. It can easily be secured to the handrail if you wish to work stationary, or if you want to remove floating fish from the center of the pen. The VØA ring™ can hold 200-300 kg of fish and can easily be lifted onto a work boat with a crane for emptying into a tank. This eliminates the need to walk back and forth with fish to empty the hand held sorting net – resulting in more efficient use of time and it is very ergonomic for the technician. The risk of escape is reduced as the fish are not lifted out of the pen with a hand held sorting net. The VØA ring™ makes it possible to complete ring rounds and removal of cleaner fish and sick or wounded fish without the work boat needing to be at the pen because it weighs only 11 kg and can be easily lifted by one person. This provides greater flexibility at the site.

The VØA ring™ is also available with a wet bag. A dedicated sorting net is under development and will be available during the fall. It is very lightweight and ergonomically designed to optimize the process of fish selection in combination with the VØA ring™

LiceSweep™ is a system for diluting lice larvae and other organisms/foreign elements in cages that reduce water quality and the living environment for salmon. LiceSweep™ is a floating filtration unit that is towed around the cage along the net wall and captures all particles larger than 0.15 mm. Based on hydrodynamics and the buoyant properties of lice larvae, it is in this zone of the cage that a high concentration of especially newly hatched nauplii is observed. By removing the lice offspring from the cage, internal infection pressure within the cage is reduced. By using light attraction at night, it is also possible to draw copepodites towards the net wall, thereby creating distance from the salmon in the center of the cage and guiding them into the zone where they can be filtered.

The system uses release hooks in the same way as the 360FishSweep™ and filters approximately 2,000 liters of water per second. It is 4 meters wide and 1.5 meters deep. The system can also be used in combination with lasers, ensuring that both mature lice and their offspring are effectively thinned out.

Vøatec is seeking collaborators to strengthen the data foundation for this method and is therefore offering this system at a favorable price in 2024 to participants who wish to contribute.
