1 Future Food and Feed from Marine Sources Dr Bente E Torstensen Director Aquaculture division Nofima AS Arctic Frontiers, Tromsø January 24, 2018

2 In a world where food security is a challenge Global Protein Sources for Human Consumption Source: FAO/

3 Potential for marine aquaculture Aquaculture Finfish aquaculture Source: FAO The State of World Fisheries and Aquaculture Contributing to food security and nutrition for all. Rome. 200 pp.

4 SDG s affect global food production Source: OECD Science, Technology and Innovation Outlook 2016

5 More food must come from the Oceans Modern aquaculture is a part of the solution Food from the oceans directly Sustainable feed raw materials for aquaculture

7 Potential for feed and food from un-utilized harvest

8 More food must come from the Oceans Modern aquaculture is a part of the solution Food from the oceans directly Sustainable feed raw materials for aquaculture

11 Aquaculture production is highly resource efficient ; Marine Harvest Industry report (2017) Lower basal metabolism; Poikilotherm animal no need for energy use to keep high and constant temperature Live in water - No need for energy use to «fight against gravity»

12 (Ytrestøyl et al, 2015) Full flexibility in raw materials

13 Search for new raw materials for fish feed in the oceans and on land - Marine: pelagic fish fish byproducts krill, calanus, copepods, blue mussels, kelp Animal: poultry byproducts domestic animal byproducts Insects: e.g. black soldier fly Plant: soya, pea, maize etc. fruits and berries algae GMO Single cell: bacteria fungi/yeast Foto: NIFES/Erik-Jan Lock Nofima/2018/BTO

14 Fish have nutrient requirements, not raw material requirements Lipid Protein Vitamins Minerals Carbohydrates

15 Nutrient requirement Feed quality requirements Tolerance for undesirebale components Composition of nutrients Technical quality Which risks? New raw material potential

16 Nutrient requirements Omega-3 lipids, EPA and DHA Cholesterol Saturated lipids Fish oil constant global supply Vit A, vit D Other components?

17 Atlantic salmon have a minimum requirement for omega-3 fatty acids, EPA and/or DHA 1 % EPA and DHA of feed (ca 3.5 % of the lipids) for growth 1,6 % EPA and DHA of feed (ca 5.5 % of the lipids) for growth, health and robustness Ongoing research > 1,6 % EPA and DHA for growth, health, robustness and fillet quality?

18 Atlantic salmon will always be a good source of EPA+DHA - due to its minimum requirement for omega-3 fatty acids 1 % EPA+DHA 1.4 g EPA + DHA 17 % fillet lipids 150 g portion

19 Need to find new sources of lipids, EPA, DHA GM omega 3 oils

23 Knowledge on nutrient requirement, raw material characteristics and feed technology to best utilise the resources to produce food Processing FOOD Carbohydrate rich sources and food production sidestreams Processing Develop/select feed raw materials not suitable/accepted as food directly

24 Feed and ingredient research in Nofima Sustainability knowledge in all steps Bioprospecting Whey raw material Marine Vegetables Animal By-products Raw material Process technology and feed technology Separation technology Extraction Extrusion Drying Bio technology Pilot production Documentation and areas for use physical/chemical microbiological Technical properties nutrient composition bio-activity feeding trials Added value pharmacology Clinical nutrition cosmetics Food/Functional foods Dietary supplements Biotech / fermentation Feed Feed additives Weaning feeds ongrowth New species

25 Future food and feed from marine sources Basic knowledge on fish nutrition and feed technology. Utilise protein, lipid and carbohydrate resources for feed to produce food. Future aquaculture is part of the solution for food and nutrition security.
