In 2011 after Bent Urup had sold UNI-Aqua /Aqua-Group Denmark, Bent Urup decided for recovering some time with his family. On the Family boat "Tao", as Jeanneau 45.1 from 1997,  he went for a sailing adventure with his family.

In July the boat left the Marina in Middlefart, for its first leg to Puerto de Santa Maria in Spain, where Dr. Urup then assisted on finalising the installation, and preparing the production startup at the Futuna Facility. 

Then in October the trip continued for the Canarian Island, where Urup with his Wife and two daughters, then 12 and 14 years of age participated in the ARC (Atlantic Rally for Cruisers), departing  November 21st. frm Las Palmas, aiming for Sct Lusia, the boat arrived weel at port after 21 days at sea.

Then from December 2011and up to April 2012, the family time  spend the time, cruising the South East Caribian Islands. 

Then late April, Dr. Urup went back to Spain, to implement the initial production at the Futuna hatchery during the summer of 2012. Within the first 10 months of production, succesful production of 5 marine species were demonstrated within the hatchery at Futuna. (Bluefin Tuna, Turbot, Kingfish, Sole, Seabass). Applying the copepod technology as previously practised at Maximus, was the succcesfull tool, in optaining a unique fry quality, and very high survival rates. Due to the finansial situation in Spain then, the Tuna broodstock facilities were though never build, and depending on Collection of eggs from cages only, there was a constant shortage of eggs.

In November the family went back to the boat, which they had left on Grenada, and continued the trip, visiting the British Virgin Islands, Dominical Republic and not at least Cuba, returning back to Denmark, in May 2013

The spinoff from this trip, was the time for reflection on previous work and development. And the advantage of having the time, to trow away Ideas if they did not satisfy the goals.

For the trip, Dr. Urup had a single academic goal. To challence the key problems and limitations, with existing RASconcepts, especially when moving into growout production.

With the time to go back to basics, and seing things from a different angle, but still implementing known technology, eventually the RAS2020 concept took form during this trip, as a solution to industrial scale landbased RAS production of fish to market size.

In May 2013, when the family went back to Denmark, the new concept was well described, and a patent application was filed, then  contact was made to Veolia(Kruger) and Graakjaer, and in cooperation with those two companies, the concept was fine tuned.

A prototype faclity in 50% scale was build in Switzerland, where those problems which are to expect on any prototy system have been solved.

Then in  Denmark in Hanstholm,  in 2016 the construction of the  first full scale RAS2020 facility was initiated, with Bent Urup as the initial driving seed investor. Production at this new RAS2020 facility (Sashim i Royal), has now been initiated for production of Kingfish, with supply of Juveniles from Maximus A/S, the hatchery which was originally developed by Urup in 1990 for production of turbut.

Now further two more RAS2020 modules are  under construction in Norway, on this project, the co-oinverstor in the Sashimi Royal (Nordic Aquaframs) (Majority shareholder),  is the investor behind the project.

As in any new developments there has been initial challenges, but the concept has truely proven, that fish performance, and production logistics outperforms any previous technologies.

In addition it comes ewith a much lower footprint, and at reduced construction costs.



RAS2020 fishfarming technology


THe RAS2020 concept includes a completely new way of doing landbased.

It is a holistic concept which integrates all important elements for succesfull fishfarming in a new super efficient setup.

The concept has a number of very important advantages compared to previous technologies.


1) Reduced footprint

2) Reduced investments.

3) Hardly any underground piping (reducing risk and time),

4) Uniform growth on fish, as all fish in batch will abe exposed to the same water quality, throughout the tank


5) Can be erected on half the time compared to conventional systems.

6) Daily harvest of fish can be implemented, without interuption on feeding regime for the fish not meant to be


7) Total water exchange within a full batch of fish in less than 30 seconds.


Standard RAS2020  are build in modules, each with the capacity to  produce between 1000 and 1800 ton of fish per year, capacity depending on fish specie and size of fish at harvest.


The RAS2020 technology is sold worldwide through Kruger(Veolia).
