Mowi now largest user of closed cages
Salmon giant Mowi has this week claimed to be the world’s largest player in closed fish farm cages.

The company said in a website announcement that it was also the first in Norway to use the technology on a large scale.
It added: “Since its inception in 2013, we have built capacity step by step, and Mowi is today the world’s leading player in closed fish farming facilities. What does it take to become even bigger?”
The first unit, which started as a research and development project, was commissioned as early as 2013.
Mowi said: “Traditional cage technology will continue to be the most important method of salmon production in Norway, but in recent years Mowi Norge has invested heavily in producing large post-smolt from closed cages at sea or recycling facilities on land.
“This is a central part of our so-called post smolt strategy, which we believe is one of the best welfare measures for our salmon.
“Farmed salmon begin their lives as fry in freshwater tanks on land. After about 8-12 months, the fry have become smolts and are large enough to be released into the sea.
“At that time, they weigh about 150 grams. However, by keeping the smolts in tanks on land or in closed cages in the sea until they have reached 700 grams or larger, the production time in the sea phase is significantly reduced.”
This, the company said this leads to fewer lice treatments and significantly higher survival for the salmon.
Now, thanks to a combination of factors, it is taking things a step further.
Last autumn the government launched the so-called environmental flexibility scheme, which was intended to encourage fish farmers to use closed production units.
The scheme gives companies that have had their production capacity reduced as a result of the traffic light system the opportunity to utilize this capacity if production takes place in closed facilities.
Mowi said it had placed an order for four closed cages from FiiZK and is awaiting delivery of one closed cage from Fishglobe Technologies.
These will be delivered over the next year, in addition to the six closed cages we already have in operation. With a total of 11 closed units in operation at sea, Mowi will nearly double its production volume to a total of 320,000 cubic metres.
