Alvestad Marin AS was founded in 2003 by Runar Alvestad. Combining the founder’s vision with partnerships with leading research and industry players, the company has, through innovation, paved the way for groundbreaking technologies and products.

Leading Technology Provider for the Aquaculture Industry

With a clear vision to be a leading technology supplier to the industry, the company has developed solutions that promote efficiency, quality, and sustainability. Through its products and projects, including the groundbreaking CompHatch hatching system with the KUBE water treatment system and the GasBuster aeration technology, Alvestad Marin has established itself as a pioneer in the aquaculture industry. The latest addition to the portfolio is the ReuseHatch recirculation system.

Collaboration with Research Institutions and Industry Partners

In 2008, Alvestad Marin entered into an IFU contract with Innovation Norway and SINTEF Fisheries and Aquaculture as research and development partners, with Marine Harvest and Smøla Hatchery and Settefisk AS as demanding customer partners. The aim of the project was to develop and test a groundbreaking concept for hatching salmon fry based on recirculation technology. After two years of intensive work, this resulted in KUBE – a compact and fully integrated recirculation plant that is energy-efficient, reliable, hygienic, and a turnkey solution. KUBE was presented in full scale at the Aqua Nor exhibition in 2009, with all water treatment steps fully implemented.

The Development of GasBuster Technology

Alvestad Marin has also developed the unique CO₂ aeration technology GasBuster, which began in collaboration with Yngve Ulgenes at Biofarm Systems and prototype testing at Marine Harvest, Kvingo in 2013, where the technology was documented by IRIS and Asbjørn Bergheim. Over several years, the technology has been further developed into an aerator that is today unique with a self-cleaning system ensuring that the aerator is always clean and therefore consistently achieves high CO₂ removal efficiency.

A Global Supplier with High Quality Standards

Our systems are in operation in all the major salmon-producing regions of the world, and we are proud to be a preferred partner for both new and established facilities. Whether for small start-ups or large industrial projects, our technology is developed to meet high standards of quality, sustainability, and reliability.
