Salmon producer Cermaq starts new closed containment system in Horsvågen
Leading salmon producer Cermaq has started production at its new closed containment system in Horsvågen, Norway, as it pursues to lead in technology development that contributes to sustainable food production.
Last weekend, Cermaq transferred smolt into the new facility to signal the start of operations in the new closed containment system, the company's first step toward developing closed farming technology.
The closed containment system is built to provide maximum biosecurity and fish welfare. Water is pumped into the pen from 13-meter depth, preventing sea lice from entering the pen. The tarp wall is made of strong and flexible composite, which minimizes escape risk. This is the world's largest closed cage using flexible walls.
"We have been working on this project for a long time, and we are happy that we now are ready to put fish into the pen", said Frode Holmvaag, manager of Seawater Nordland in Cermaq Norway.
"This is new technology to us, and it will be very interesting to follow the growth and development of the fish in the new containment system".
The new closed containment system, which has been constructed in partnership with Botngaard AS (which has long experience with constructions for the aquaculture industry) and Serge Ferrari, is certified for locations with a significant wave height of two meters, and can be used at most existing sea sites.
"The delivery and start-up of the closed cage in Horsvågen mark a milestone for Botngaard and our development program for closed cages. We will now work together with Cermaq and our industry partners to further improve the technology and daily operations of the cage", said Magnus Stendal, system delivery manager in Botngaard.
Serge Ferrari, world leader in innovative flexible materials, has developed the membrane wall that makes the containment system flexible and safe.
