Ecomerden is a complete producer of semi-closed cage systems for Aquaculture founded in 2012. With over 25 years of experience in delivering technology in the aquaculture industry, we started developing Ecomerden, a European patented semi-closed system for the lice-free production of fish. By 2015 the first cage was installed in Solund. Sogn & Fjordane. Here we have produced lice-free post-smolt of Atlantic salmon (90 grams-1kg) for 2 years with groundbreaking results. Using Ecomerden as a combination in the production line of the fish not only prevents lice pressure but also makes a more robust smolt ready for the open cages. With the results so far showing that the technology and biology are working, the company is now ready for commercialization.
