New research centre for Atlantic salmon opened
Krüger Kaldnes is one of the technology suppliers for the new research center on closed containment systems for Atlantic salmon.
Four Norwegian research institutions, two outside of Norway and several industry partners from technology and the aquaculture industry have now started operations at a centre for innovation in closed-containment systems. The centre, CtrlAQUA, has been given NOK 200 million and eight years to reach its own ambition to make closed-containment systems for salmon up to one kilogram off-the-shelf systems.
On Tuesday May 26, Norwegian Minister of Fisheries Elisabeth Aspaker honored the centre by visiting Nofima at Sunndalsøra as part of the opening of the centre: "I have great expectations for the achievements of CtrlAQUA. Even though 8 years is a long time, it is urgent that we find solutions to reach the goals. CtrlAQUA is an important part of this," said Aspaker.
Opened by The Research Council of Norway CtrlAQUA is one of the Centres for Research-Based Innovation (SFI), a major program created by the Research Council of Norway.
The formal opening by the Research Council took place on Wednesday May 27 during a kick-off meeting at Sunndalsøra, Norway, when Director of Innovation in the Research Council Eirik Normann presented the SFI plaque to CtrlAQUA Centre Director Bendik Fyhn Terjesen of Nofima.
The primary goal of the SFI program is to strengthen companies' capacity for innovation, and to develop leading industry-relevant research institutions. Nofima is accompanied by five solid research institutions in CtrlAQUA: Uni Research, the University of Bergen, the Norwegian University of Science and Technology, the Freshwater Institute in the US and the University of Gothenburg in Sweden.
Solving challenges limiting growth in aquaculture Aspaker stated in her speech on Tuesday May 27 that the goal of the CtrlAQUA SFI is perfectly compatible with the government's ambitions for the aquaculture industry. The report "Value creation from productive seas in 2050" predicts that aquaculture will have increased in volume five times and increased in value eight times in the years until 2050.
Technological and biological innovations in closed-containment production systems, in which the environment of the salmon is separated from the surroundings by an impermeable barrier, may be important for the development of the Norwegian aquaculture industry.
The main focus of the centre is innovation in closed-containment systems for the most vulnerable periods of the salmon production cycle, such as the first seawater phase, known as the "postsmolt" phase, when the fish weigh up to about 1 kilogram. The most important innovation in the centre will be reliable and efficient production of postsmolts in closed-containment systems on land or in the sea. The industry can in this way obtain a good alternative or supplement to the current production technology using open cages.
New aquaculture contract awarded Krüger Kaldnes
Krüger Kaldnes has signed a DB contract for delivery of a new RAS (Recirculating Aquaculture Systems) plant to Osland settefisk in Sognefjorden, Norway.
The contract comprises delivery of a complete Kaldnes® RAS solution for a greenfield smolt hatchery. Deliveries include process- and electrical equipment and installation for hatchery and fry departments.
The project has been developed in conjunction with the Danish company Gråkjær that has been awarded the contract for civil works incl. tanks and piping and other auxiliary equipment. The contracts to Krüger Kaldnes and Gråkjær will together constitute the delivery of a complete smolt hatchery.
"We are very pleased that Osland settefisk chooses Krüger Kaldnes as their supplier to the construction of this new recycling facility. We have developed a new and innovative way to treat recycling water that is environmentally friendly, energy efficient and extremely compact. The concept has been warmly welcomed by many aquaculture farmers in Norway and internationally and we have great expectations to further develop the land based aquaculture market with our Kaldnes® RAS solution, "says Marius Haegh, Vice President - Aquaculture in Krüger Kaldnes.
Giant commitment on salmon smolt in Nordland
Helgeland Smolt, with Krüger Kaldnes as processing supplier, is now building what seems to be the world's biggest production site for salmon smolt, (which is a juvenile salmon ready to be released in sea cages) - at Reppen in Rødøy municipality, in the county of Nordland. The production site will contain seven departments from hatching till extended growth. The process can manage both salt- and freshwater. Total basin volume is 21.700 cubic meters. Optimal production will deliver 7 to 8 million juvenile fish with a biomass (weight of the fish) reaching 2000 metric tons. The hydraulic capacity in the recycling site for the process water totals 35.000 cubic meters per hour. Total building costs will amount to abt 300 million NOK.
- Our goal is a good site with an equally good technological solution, says Tor-Arne Gransjoen, general manager in Helgeland Smolt. He is a pioneer in the development of this kind of industry in his home county and he is also the driving force in the successful site of Sundsfjord Smolt. But despite an expansion the capacity again has reached its full peak. The choice has been between another expansion - or a new production site.
- We just had to adjust the capacity if we should keep up. Due to a risk assessment the choice fell on a new site. For us it will give better supply guarantee if one of our sites, against all odds, shall have to close down for a limited period of time, says Gransjoen, who can add that affected authorities, local as well as on county level, are very positive to the new project.
As mentioned earlier this is a production site with a unique size - with basins for fish up to 500 grams. We have interviewed Bendik Fyhn Terjesen, senior researcher at NOFIMA situated in Sunndalsoera. Here NOFIMA has made several tests with salmon smolt in recycled water. On a general basis, independent of supplier, mr Terjesen sums up their research so far, in view of both size of the fingerling and its welfare:
- Research this far shows that the fish, after being raised in enclosures both on land and sea, have a high rate of survival. With reduced salinity in the water in RAS, a better fish skin health is also obtained. Good fish skin health is very important at this stage of growth and reduces mortality when the fish is let go in new environments. At the same time the growth in the sea is equal to, if not better, than by traditional smolt production.
Lately there has been an intensified debate concerning the aquaculture industry and the increasing occurrence of salmon lice.
- When the fish is in enclosures on land the said lice will be either reduced to zero or kept on a minimal level. Longer time in closed facilities will no doubt reduce the spreading of salmon lice, due to the fact that salmons are kept for a shorter time in sea-cages (merds). Therefore the use of enclosures on land will become a very important means of combating especially the salmon lice. Improved technology and thus water quality is a very hot topic in the aquaculture industry. Therefore, more research is now engaged in such work, he says.
Current regulations allow for closed land produced smolts up to one kilogram. It would be useful if it could also include sea-based fish closed containment.
- Currently we have done experiments with fish up to one kilogram. It has gone well when adding some special care and a few adjustments during relocations. So it looks promising, concludes Terjesen.
Aquaculture-director of process-supplier Krüger Kaldnes, mr Marius Haegh, has enough to keep him busy for the time being.
- We are experiencing a rapid development, with larger deliveries. The facility at Marine Harvest in Steinsvik on Sunnmoere is large. But Helgeland Smolt on Reppen will double this size. Our RAS is founded on the unique MBBR cleansing technology developed at NTNU in Trondheim, Norway. We supplied Sundsfjord. Now we are also selected as supplier for this great initiative. Internationally we are attracting new customers. We are proud, concludes mr Haegh.
