Columbi Salmon has brought in Bent-Are Ratvik as Head of Operations in Oostend. Ratvik comes from Refsnes Laks and will play an important role in developing Columbi’s salmon farming operations.
Nordal enters the Columbi Salmon team in May and will play an important role in accelerating the company’s growth.
(Åfjord, Norway) Columbi Salmon has partnered with Norwegian Institute of Bioeconomy Research (NIBIO), Morefish and Biomar on a research project aimed at reducing the carbon footprint of salmon farming in Recirculating Aquaculture Systems (RAS).
Tanks for small fish
After hatching, the fish is moved to tanks, where they remain in fresh water until reaching 100-300 grams. In this phase, the smallest fish are called fingerlings, while the larger fish are referred to as smolt.
Grow out stage
The grow-out stage corresponds to the period when the fish in traditional farming are moved from fresh water on-shore, to the ocean. Meanwhile, in our system the fish are transferred to the largest grow-out tanks.
When the fish reaches its target weight (4-5 kilos), it is transferred to the primary processing plant, which is situated next to the largest grow out tanks. The fish is slaughtered, and gutted salmon, including the head, is packed in ice-filled boxes and transported to consumers.
The fresh water from the fingerling/smolt phase is normally taken out and cleaned for particles and nutrients. In our system, some of this water will instead be transferred to a large greenhouse (aquaponic) which has the capacity of growing up to 4,000 tonnes of salad annually, without using a single gramme of soil.
