Norwegian company Niri AS has built the world’s biggest land-based tank for growing full size fish.   26,000 juvenile salmon have been stocked into a 1,600 m3 tank at a former airbase in Machrihanish, near Campbeltown in Scotland.



Fish Farming Facilities


Niri’s business strategy is to own and operate fish farming facilities rather than the selling of parts and equipment, enabling others to farm the fish and gain the profit.

A New Concept in Modern Fish Production


Niri presents a completely new concept in modern fish production and is based upon three integrated stages that result in huge cost savings impossible to achieve by conventional sea cage farming industry.

Uniquely, each Niri tank is basically a separate unit, where all the water treatment processes of filtering, de-gassing and ammonia control are all integrated into each tank. Hence the water is not taken out of the tank but rather cleansed and re-circulated internally throughout each tank. The energy consumption for pumping water is in fact not more than the energy used for underwater lighting in conventional sea cages (the average of cod and salmon farming).

Several attempts have previously been made to grow salmon in land based systems, without success.  Niri’s integrated water treatment system has resolved the issues from the earlier attempts, high investment costs and high pumping costs.  Niri simply cleanse and recycle the water without pumping it out of the tank rearing system.  Hence Niri’s system is easy to build and operate, producing large quantities of fish of the same size.

One site integration


A Niri facility has all the productions stages integrated at the one site, from smolt to final processed product. As a result, there is no need for any well boat/truck to transport fish between the differing production units, nor any ice, boxes or additional logistical operations. Instead, the fish are moved directly from the grow-out tanks for processing, in a stress-free way and slaughtered rapidly and humanely. These “rested” fish, when in a pre-rigor condition, will have a much better quality than fish from traditional processing. 

 

Niri Scotland’s Chief Executive Officer Arve Gravdal states:

 

“Our system is unique. What we have done in Scotland is to prove that our technology works and that we now can build industrial scale salmon farms anywhere in the world.” 


Veterinary reports from Niri’s earlier test units state that the fish is of very high quality, like wild fish.

 

Mr Gravdal says: “Other species are also possible.  Our farms have the potential to spark the start of development to tackle a worldwide problem - namely providing enough protein to feed a growing population.”
