1 Industrial Parks for Aquaculture now launched in Spain Victor Øiestad Dr. Phil. Akvaplan-niva niva - Norway Spanish office

2 Industrial Production Centres for M Seafood launched in 1992 front of a four- pages folder

3 Re-launching IPCS or IPA during AquaNor-1995

4 THE FIRST PLAN FOR 25 IPAs IN GALICIA (March 2005)

5 A SECOND PLAN FOR 26 IPAs PLAN GALEGO DE ACUICULTURA (REVISIÓN DO PLAN SECTORIAL DOS PARQUES DE TECNOLOXÍA ALIMENTARIA) (DOCUMENTO PARA INFORMACIÓN) JULY 2007

6 INDUSTRIAL PARKS FOR AQUACULTURE SUITED FOR NICHE SPECIES & FISH JUVENILES NICHE SPECIES FLATFISH (TURBOT, SOLE, HALIBUT) HIGH VALUE DEMERSAL FISH SPECIES HIGH VALUE PELAGIC FISH SPECIES JUVENILES PRE-SMOLT SALMONIDES SEA-BASS, SEA-BREAM, COD AND COMMODITY SPECIES IN GENERAL

7 Is niche species production lucrative? An illustration from Spain Stolt Sea Farm (PRODEMAR, Galicia) produced about 4,000 tons of turbot in 2006 at 8 to 12 Euro per kg with a final profit of 3 Euro per kg. 12 million Euro in profit in 2006 Conclusion: : Niche production could be lucrative for both small - and large enterprises (like SSF)

20 Advantages of the Shallow Raceway System (SRS) compared with Conventional Tank System (CTS) 1. SRS demands far less coastal land than conventional farming technology (depending on the number of levels it can be about 20% for the same biomass production as with conventional tank system = CTS [assuming 8 levels]); and it need for the same reason a far smaller building for the same biomass; these are the two main investment gains from the SRS. 2. SRS can be built at some distance from the coast since its needs for water replacement will normally be lower estimated to down to 30% of conventional system. 3. SRS will demand less people as many functions will be robotized - for a big farm (>1000 tons) estimated to about % of the staff at a CTS of same production capacity. 4. SRS design can more easily be fish-friendly takes care of animal welfare-aspects - and operator-friendly. 5. SRS can be installed as modules called towers - in pace with the increase in biomass to reduce start-up costs, so the initial number of fish can be that of the full-sized farm. 6. The enterprise can step-by-step increase its efficiency and thus profit from a lasting gain in productivity. 7. SRS is flexible with respect to choice of species to be farmed as pelagic and benthic-pelagic fish species can be farmed in the system as well. 8. The use of floating pellets and moveable screens in the tanks in SRS makes it possible to keep high fish density through the system at any time and at any size - with about 300% cover of bottom thus offer an overall 30% higher standing biomass for the same tank surface as with CTS. 9. The use of floating pellets in SRS may reduce FCR with 10% so less feed is needed for the same weight gain. 10. The gain in fish biomass per m² tank is expected to be higher in shallow raceway, mostly due to an overall higher standing fish biomass in SRS/m² then in CTS; the specific growth rate may also be higher due to easy access to floating pellets. The net biomass gain will be in favor of the SRS. 11. Survival rates in SRS will be the same as in CTS or better - unless something peculiar happens in one of the systems. 12. SRS is easy to connect to any water source and it is easy to reuse or re-circulate the water; in a flow-through system with reuse at the same level or between levels, the SRS will use about 30% of the water used in the CTS in biomass equivalent (l/kg x min).
