This project links together two diverse but important areas of national importance: declining fisheries and human health. Australia is a small producer and exporter of fish but has access to significant fisheries. The Geelong Food Co-product Cluster comprises a number of fish companies facing serious problems associated with declining catches compounded by the current financial crisis. Increasing use of by-catch species and developing novel processing technology for controlled release of bioactive peptides that may reduce appetite and the tendency for overweight and obesity in consumers could provide the Australian seafood industry with a world competitive innovative technology leading to improvements in human health.Read moreRead less

Understanding and implications of formation of lipid nanostructures in milk. This project aims to deliver new understanding of the processes of milk digestion. Milk is the most important food for human survival, providing all the essential nutrition to newborn infants and constituting a major part of the adult diet. The recent discovery that nanostructure is formed during the digestion of both cow and breast milk, but not of vegetable 'milk', has opened a large number of questions to answer in t ....Understanding and implications of formation of lipid nanostructures in milk. This project aims to deliver new understanding of the processes of milk digestion. Milk is the most important food for human survival, providing all the essential nutrition to newborn infants and constituting a major part of the adult diet. The recent discovery that nanostructure is formed during the digestion of both cow and breast milk, but not of vegetable 'milk', has opened a large number of questions to answer in this project. Specifically, the project plans to link nanostructure formation in milk with composition during digestion, and the subsequent delivery of nutrients. The project plans to use synchrotron and microscopy techniques to address these questions. Project outcomes may improve our understanding of digestion and drive innovation in products delivering nutrients to infants.Read moreRead less

Marine fisheries cannot expand further, leaving aquaculture (fish farming) with the challenge of meeting the growing demand for fish, whose consumption is known to enhance human health. Fish oil is an essential component of the feed used in aquaculture, but there is a decreasing global supply of this commodity. This innovative nutritional biochemistry project boosts the capacity of fish to produce their own fish oil from vegetable oils in their diet. Therefore, this project will enable the expansion of aquaculture as an economically and environmentally sustainable means to produce the highest quality, nourishing fish for human consumption.Read moreRead less
Omega-3 fatty acids, appetite and growth in farmed fish. Australia has very limited wild fish supplies, and with the increasing realization of human health benefits of fish (i.e. omega-3 fatty acid) there is a need to increase availability through aquaculture. However, feeds used in aquaculture contain costly fish oil with limited global supplies. Attempts made to substitute fish oil with vegetable sources in aquaculture feeds have been mixed. This international, comparative and multidisciplinar ....Omega-3 fatty acids, appetite and growth in farmed fish. Australia has very limited wild fish supplies, and with the increasing realization of human health benefits of fish (i.e. omega-3 fatty acid) there is a need to increase availability through aquaculture. However, feeds used in aquaculture contain costly fish oil with limited global supplies. Attempts made to substitute fish oil with vegetable sources in aquaculture feeds have been mixed. This international, comparative and multidisciplinary project aims to reduce the dependence on fish oils through investigation of basic fatty acid metabolism and endocrinology on farmed fish to ensure that human health promoting characteristics in the final product are retained.Read moreRead less

There are two main benefits of our research to Australia. Firstly, the team that we have assembled have international reputations, and include scientists from overseas. This team will be led by Australian Institutions and will put Australian science in the forefront of a competitive field, internationally. Secondly, our research examines questions that are critical in our understanding of how animals respond to stressful events. The response to stress, if excessive, leads to ill-health in both humans and other animals. Our research examines new connections between stress and fish biology, which could lead to discoveries that are valuable in managing stress and health in wild and farmed fishes.Read moreRead less
Programming of appetite and bodyweight by the interaction of maternal diet and angiotensin during peri-natal life. The project describes a phenotype for appetite and body weight that can be altered by maternal dietary omega-3 PUFA (environmental factors), at a critical period during peri-natal life (developmental phase) and that the effect on body weight is opposite when endogenous angiotensin is increased (hormonal factor). The project aims to discover how these different factors interact to p ....Programming of appetite and bodyweight by the interaction of maternal diet and angiotensin during peri-natal life. The project describes a phenotype for appetite and body weight that can be altered by maternal dietary omega-3 PUFA (environmental factors), at a critical period during peri-natal life (developmental phase) and that the effect on body weight is opposite when endogenous angiotensin is increased (hormonal factor). The project aims to discover how these different factors interact to produce the phenotype by defining the critical period and systematically identifying genes that are expressed during this period. The effect of manipulating maternal dietary omega-3 PUFA and the role of angiotensin will then be examined. The project will discover how genetic, hormonal and environmental factors interact during the perinatal period of life to program food intake and body weight in adult life. Read moreRead less
