In 2012 Dr Fernando Norambuena moved from Barcelona to Australia, to work in biochemistry and fish nutrition at the School of Life and Environmental Sciences of Deakin University at the Warrnambool Campus. Fernando has a doctoral degree in fish nutrition and reproduction from Autonomous University of Barcelona, during his thesis he was working at the Institute for Food and Agricultural Research and Technology, IRTA -Catalonia, Spain with interships at Stirling University, UK. Previously, he did his Master degree in Feed Technology in Norway at the Agricultural University of Norway (Aas). Fernando started his career in Chile, where he got the Engineer degree in Fisheries from Austral University of Chile in year 2000 -Puerto Montt.

At Deakin Fernando is addressing a greater understanding of the complex interactions between dietary lipids requirement -i.e. long chain fatty acids and cholesterol- deposition, and fish health, and fish plasticity to cope with changing environments including water temperature. He has studied lipid mediation in fish welfare including inflammation and immune system pathways, and the effect of the environment in the nutritional fish requirement. He also has studied the capacity of fish to self-select their diets including fatty acids by using automatic self-feeders under diferent water temperature fluctuation -i.e. adaptive nutrition. He has been working for seven years on the metabolism and dietary requirements of fatty acids, as well as arachidonic (ARA) and Eicosapentaenoic acid (EPA) with focus in bio-conversion of ARA into eicosanoids -i.e. prostaglandins, leukotrienes and isoprostanes. He has studied the dietary modulation of these fatty acids affected water temperatures, with focus on transcription rate of key enzymes involve in their biosynthetic and their possible interaction on cholesterol, steroids and stress biomarkers. In other hand he has been addresses potential and successful use of Australian agricultural by-products in aqua feed, as well as local seaweeds. Fernando has conducted extensive research on the biochemistry of fish nutrition including those factors contributing to reproductive problems of broodstock fish and he has been involved in research projects on animal feed production and the optimization of feeding systems in fish farms in Norway, Spain, Chile and Australia.
