About us

land-based fish farmingMaiken Food AS is a company from Norway founded by Arve Gravdal. Also, Arve is the inventor of new technology and that will be a game changer when it comes to land-based fish farming.

Maiken’s RAS (Recycling Aquaculture System) consists of individual tanks, without interaction with other tanks. In other words, tanks are independent. It is a new simple technology where water is recirculated by cleansing it inside the tank.

Our first project of land-based fish farming in Portugal is planned in Sines, where we currently lease a large industrial site, which is close to the Atlantic ocean. Significantly important that solar panels will power the entire fish farm, and CO2 from the tanks will be used to make protein for feeding fish.

As a result, this will be a fantastic project with a circular economy, and it is extremely ESG friendly. That’s the main argument behind its creation. Moreover, no long transport stages with emissions and using green energy from the sun.

The advantage of the project is that we can start building and setting fish into the tank before the whole facility is ready. Since tanks are completely independent. 

The cash flow will start in the first year of operation after the beginning of the construction.
