ProximarSeafood AS is a Norwegian land-based salmon farming company with its first production facility in operation at the foot of Mount Fuji in Japan. The company inserted its first batch of eggs in October 2022 and plans first harvest in Q3 2024.


Our fish farming is based on Recirculating Aquaculture System (RAS)-technology, provided by AquaMaof. The industry-leading technology has a solid track record and provides ideal growth conditions for Atlantic Salmon, with low inherent complexity. The system has a high degree of modularity, redundancy and buffer capacity, leading to efficient production and lower operational complexity.

By land-based fish farming, we are able to produce high quality Atlantic Salmon in a closed environment without impacting our surroundings. Our production is free of medication, without influence from traditional challenges such as lice and microplastics. Producing the salmon locally also means great reductions of carbon emissions from transportation. Proximar has a systematic approach to sustainability, meaning that environmental and social responsibility is integrated into our planning and conduction of our operations. We have received Cicero’ Dark Green classification as a testament to the sustainable nature of our business
