2 RAS A Game Changer GFIA 204 Bent Urup

3 RAS The middle east becomes a location for fishfarming. Game Changer: With RAS, fish can be produced close to markets, almost anywhere in the world, Fish can be produced independently on local temperature regimes. Access to freshwater not essential. Only small amounts of either freshwater or seawater required. The very most desired species can be produced, as we are not limited by nature given conditions. Investments and operation costs are now becoming equivalent to cage farming. RAS turbot facility. South China, chilled facility. Local high value live fish market. RAS delivery: UNI-Aqua A/S 3

4 Requirements Access to juveniles general limited access to juveniles of marine species like Groupers, Seriola (kingfish) and Tuna. All year supply is required to optimize output from RAS growout unit. Access to RAS technology farming of marine fish more profitable, but technology more complicated. Access to some amounts of freshwater or seawater. A total of 40 l. to 400 l. of water is required per kilo production of fish. (against l in flow through) Energy: The energy requirement is,5-2,5 KWh, per produced kilo of fish. Pictures: larvae development, Seriola. Photos, Mark Russell. Read further: 4

5 Marine fish Fry for RAS production Fry for RAS facilities, should be produced in a pathogen free environment too. Availability of Fry is a limitation for the industry, can be difficult to produce, due to the requirement of Fatty- and amino-acids. Further all year supply is required to generate optimal revenue from RAS farms. The fry production technology, original developed at Maximus ( has been applied in several hatcheries. It has proven, a very suitable solution for production of fry of kingfish, tuna, turbot, sole, cod and halibut, and has a potential for grouper production as well. Pictures: Copepod production tanks and turbot fry from Maximus. Tuna fry, gut opened with copepods (Futuna Blue), and tuna juvenile 7 weeks ph. Photos of tuna by Thomas Hofmann. 5

7 Carbon equilibrium in seawater In seawater the majority of CO 2 will transform into HCO 3-, which cannot be stripped out. The CO 2 stripping then has to be very efficient to maintain a balance with a low total CO2/bicarbonate pool, otherwise growth reduction and a poor FQ will develop. A stripping devise of the media/surface contact type, with gravity water flow under vacuum, is one of the few that performs efficiently in seawater. Right the Kruger Kaldnes /Veolia CO2 stripper. Aeration type of strippers are insufficient. 7

8 Risk elements Technology general not a problem, there are several serious suppliers, even only a few can offer systems suitable for seawater. Project execution: One of the biggest risk, are gabs in the list of responsibility between suppliers, where critical elements might not be counted for. Chinese box syndrome, fish-farming looks simpler and less complicated on the outside than is. Delays in construction. Production output/revenue will be missing in budgets. Critical that growout facility is ready,when juveniles arrive. If a full year revenue is missing can the company cope?, will the supplier cover the losses? Lack of liquidity up to cash flow. Attention to details and standardisation procedures in design is important. On the picture what should be a fixed submerged fluidized bio-filter, only on the day after initial start up. 8

9 Aqua culture in RAS - The Chinese Box What appears that simple at first glance, hides multi layers of complexity. Which requires an integrated solution in the one and same solution, normally without option of a later fix. Engineering Fish behaviour Pathogens population dynamics Husbandry Water chemistry Fish feed Fish handling Fish tank dynamics Production Planning Financial management Fish quality Market requests Environmental regulations

10 Solution Turnkey standard deliveries What would the cost, the delivery time and the quality of your car be, if it was custom made, based on local part suppliers, and build by the local garage /workshop? Standardized Patented RAS-concept by Veolia. Standardized car concept by BMW. On deliveries of RAS facilities, clients will expect low risk on functionality, quality, delivery time and a supply at a cost, which will generate a satisfying profit in production.

11 Production costs in RAS General budget on production cost in RAS, source, Capital costs: Turnkey RAS unit: 4-7 EUR/kilo production capacity. - equivalent to capital costs per kilo production capacity in cage farming in Norway on infrastructure and concessions.

12 Danish Salmon. RAS 2000 ton Salmon/year From egg to harvest. A project which shows the future on how to produce fish efficiently close to markets and processors, but not how to do future RAS installations. The Integration between suppliers to complicated, incomplete, and causing critical delays. Construction time/time to cash flow to long. Concept development, Bent Urup Construction: Graakjaer ( Supplier of RAS2020, and turn key RAS projects in joint delivery with Veolia) WTS- equipment, AKVA.

13 Sashimi Royal A/S New RAS project with RAS2020 technology ton capacity annually of Salmon/kingfish. Supplier: Graakjaer /Veolia Production costs and investments competitive with cage farming. Optimal location, logistics/transport 3

14 RAS KK - Veolia Standard design and production concept. 200 ton salmon /year. Equipment package delivery with design package. Local execution of construction, installation of tanks, piping and building to specifications. Industrial scale, standard unit, designed to production logistics of Salmon. 4

15 RAS2020 KK - Veolia 30% reduction investment 50% reduction in construction time Elimination of main risk on execution/construction. Industrial scale, standard unit, flexible production. Perfect Lego concept for turn Key deliveries. Optimised operation. 5
