  3. Aquaculture Ghent University: IOF-consortium Interfacultair Centre of Excellence • Sustainable Aquaculture – Blue Economy • Multidisciplinary • 3 faculties • 7 research groups; 9 professors • ~100 researchers

  4. Blue biotechnology at workforPeople, Planet and Profit • Industry • Improvedyields • Improvedquality • Reduceddisease • Society • Sustainability • Foodsecurity

  5. Key Partners in Aquaculture Ghent University • Fac. Bio-Science Engineering • Patrick Sorgeloos (promotor) • Peter Bossier (co-promotor) • Colin Janssen • Nico Boon • Fac. Sciences • Dominique Adriaens • Marnik Vuylsteke • Fac. Veterinary Medicine • Hans Nauwynck • Annemie Decostere • Wim Van den Broek

  6. Main goals of Aquaculture Ghent University • Increaseinteractionwithindustry • Building a strategic patent portfolio • Valorization of availabletechnology and IP • Partnering (industry/stakeholders) • Diffusion of knowledge • Boostingsynergyamongmembers

  7. Sustainable aquaculture – the “learning curve”from an empirical approach to a knowledge-based industry Bottlenecks for the aquaculture industry: • yields and rentability very variable, still too un predictable • limited knowledge of the biology of the cultured species • limited automation & system control

  8. Priorities for future aquaculture from empiricial farming towards a knowledge-based bio-industry AQUACULTURE : BLUE BIOTECHNOLOGY OF THE FUTURE ? resulting in new concepts & products for a sustainable aquaculture

  9. Priorities for future aquaculture • Complete independence from natural stocks through DOMESTICATION • Improved / more cost-effective SEEDPRODUCTION • Better targeted SPECIES SELECTION • Development of more efficient stocks through SELECTIVE BREEDING • More MICROBIAL MANAGEMENT for more sustainable production • Better understanding of IMMUNE SYSTEMS in vertebrates and invertebrates • More INTEGRATED PRODUCTION SYSTEMS for plant and animal farming • COASTAL AND OFF-SHORE FARMS of food and energy • Full independence from fisheries stocks for LIPID AND PROTEIN INGREDIENTS in aquatic feeds • More attention for INTEGRATION of restocking activities with FISHERIES management • SOCIETAL LEVERAGE: • multi-stakeholder interaction • International cooperation on a win-win basis

  10. Microbial management in larviculture Goal: health management • Improvelarval survival • Alternative techniques for disease prevention How? By steering host-microbial interactions • Stimulating the host’s immune response • Immunostimulants: yeast cell wall-bound glucan • Heat shock proteins: upregulate immune system • Influencing microbial numbers or microbial activity • Polyhydroxybutyric acid • Quorum sensing

  11. Morphology • Morphological development of larvae • Gastro-intestinal development in larvae • Artemia (brine shrimp) • Seabass

  12. Opercular deformaties in gilthead seabream

  13. Methodologicaltestingforin-depthanalysis of skeletaldeformities • Bone Mineralisation • Bone Cell Proliferation • Bone Matrix Organisation • 3D Characterisation of deformities • 3D Modelling of mechanically induced deformities • Kinematics of vital functions Basedon micro CT data

  14. Aquatic Veterinary Medicine • WSSV research • Edwardsiella & Flavobacteriumfish diseases

  15. Hydrocephalus in burbot (LotalotaL.) larvae

  16. Swim bladder hyperinflation in burbot (LotalotaL.) larvae

  17. Nutritional research • Live food production • Artemia: culturing biology, natural occurrence, production techniques, strain characterization, nutritional value enrichment; automation in production & cleaning techniques • Rotifer culture and enrichment • Micro-algae • Special focus on production, nutritional manipulation (lipids, vitamin C and E)

  18. Genomics • Genome sequencing of Artemia • Proof-of-concept as a model organismforCrustaceans

  19. Environmentalmonitoring & design of integratedconcepts • Biofloc technology • Nitrogen recovery • Waste to feed • Biopolymers • Compound poly--hydroxybutyrate (PHB) • Disease control and growth promotion
