About us
GreenFox Marine was established in 2020 as a spin-off of GreenFox, which was established in 2016. Based on GreenFox’ control system technology and the development of high-resolution ultrasound equipment from Aurotech Ultrasound AS, the idea emerged for a system that could separate smolt by gender. This technology and the experience of our founder, Roger Gullikstad, in the development of high-resolution ultrasound equipment at Aurotech Ultrasound AS was the point of departure for GreenFox Marine AS. Although several areas of application were evaluated, combining GreenFox technology with the use of high- resolution ultrasound, gender-sorting of fish stood out as being the most relevant.
Halvard Andresen is the company COO and project manager. He is the founder of MASKON, which was sold to Skala in 2013. The company name is now Skala Maskon. While Halvard Andresen was at Maskon, several technical innovations were developed for the aquaculture industry, including high-speed sorting machines for fish roe and state-of-the-art fully automated vaccination machines for smolt vaccination. Halvard’s expertise in robust aquaculture solutions and his extensive network in the industry are vital assets.
Our team’s expertise covers electronics development, high-resolution ultrasound, mechanics automation and artificial intelligence (AI). This has moved us forward, with a strong focus on implementation and time to market.
Through collaboration with a world leader in broodstock breeding of salmon, AquaGen AS, who have conducted extensive research into the use of ultrasound with salmon, we have acquired considerable expertise.
Our technology is scalable, and our ambition going forward is to supply solutions that can identify the internal qualities of a fish, to be used with other species of fish, etc.
