2 Cage farms Land Based Aquaculture Recirculation Feeding Barges Feed systems Sensors & operational Software

3 What can Land Based deliver? Systems for industrial use Recirculation Aquaculture Systems (RAS) Flow-trough systems (FTS) Installation & Supervision Piping and pipe works Fish tanks Controls Intake water systems Heating and cooling systems Effluent treatment Pre-project work 3

4 Basic RAS 1 % of system volume going out per hour 1 % new water of system volume going in per hour Recirculation Aquaculture System (RAS) 100 % of system water recycled per hour 100 % back Basic RAS: litres new water pr kg feed per day Basic RAS: All system water exchanged in 4 days

5 Zero Water Change (ZWC) RAS 0,1 % of system volume going out per hour 0,1 % new water of system volume going in per hour 100 % recycled per hour Plate separator De-nitrification 100 % back Phosphor removal ZWC: litres new water pr kg feed per day ZWC: All system water is exchanged in 40 days

9 Smolt RAS Tasmania Huon Auaculture Intake water systems Hatchery Start feeding Parr Smolt Effluent treatment Construction period: 2 years In operation: 2015/2016 Project value: EUR 7,2 mill 9

10 Smolt RAS Chile Sealand SA, Puerto Montt 12 mill. Smolt per year Hatchery Fry Parr systems Smolt systems

11 Smolt RAS in PE Fister Smolt Norway RAS PE-RAS solution 4 pcs Ø 12 meter tanks Project value EUR 2,8 mill

12 Cleanerfish systems Namdal Rensefisk AS - Cleanerfish AKVA GROUP LB project value: 56 mill NOK

13 RAS: Rompin Marine Hatchery, Malaysia Department of Fisheries Malaysia Goal to expand marine cage farming Securing sufficient numbers of fish fry 5 million fry per year seabass, barramundi, grouper etc.

14 RAS: Khalifa Marine Hatchery, Dubai Umm al-quwain, United Arab Emirates Mass production of marine fry for aquaculture in the Gulf Grouper and Bream species Constructed in 2014

15 Case: RAS Shrimp Farming, Thailand The Charoen Pokphand Foods Co. Ltd. (CP), Thailand Bio-secure super intensive indoor shrimp production system Harvest output of 25 kg per m2 per harvest Pioneering systems up and running

17 Key points in bio-security design Site selection Water intake treatment Super structure Staff & visitors System design Operation & production planning Site infrastructure

18 Site selection Avoiding diseases is key Water quality most important Fresh water, river, stream, well, borehole Saltwater intake, beach drains or similar Other nearby farms? Other risks?

19 Water intake treatment Treatment, almost always Mechanical filter or sandfilter Ozone treatment UV Aeration

20 Super structure Insulated building always Minimizing impact from outside Risk limited to deliberate input: Water, air, people, feed etc. Heating/chilling (titanium if seawater chilling)

21 Staff & visitors Biosecure entry - bench Wellies Hand desinfectant Coats Visit in the right order Staff foot baths

22 System design Fish logistics flow RAS design state of art Input: Eggs only Fish out at other end Grading platform Vaccination - injection Salt treatment system Dead fish collection & disposal

23 Operation and production planning Only eggs in and desinfected All in - all out for incubation, first feed, fry Smolt and On-growing overlapping Fauling of RAS? System desinfection for all in all out, NaOH Biofilter start-up, inoculation Daily operation and hygiene

24 Site infrastructure General process flow & no cross contamination Water intake/treatment System design flow Automated central feeding Central lime (ph) & salt dosing Lorries in out (feed, mort, sludge) Well boat of fish trucks Staff logistics Waste water treatment area Morts collection & disposal
