Triggering the dormant capacity of fish to make omega 3 fatty acids. 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.

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
Early life overfeeding - mechanisms for programming obesity and long-term immune dysfunction. Early life overfeeding can lead to obesity and related changes in adulthood. With this study we will discover how overfeeding can permanently alter an animal's development so that its body weight and immune functions are dysregulated. The outcomes will facilitate appropriate design of animal experiments considering the impact of neonatal programming. They will also contribute to more efficient feeding p ....Early life overfeeding - mechanisms for programming obesity and long-term immune dysfunction. Early life overfeeding can lead to obesity and related changes in adulthood. With this study we will discover how overfeeding can permanently alter an animal's development so that its body weight and immune functions are dysregulated. The outcomes will facilitate appropriate design of animal experiments considering the impact of neonatal programming. They will also contribute to more efficient feeding protocols for meat production in agriculture and identify targets for risk management and for preventing and ameliorating early life overfeeding effects in humans. This investigation therefore has clear benefits to the social, economic, and health aspects of obesity and to basic science and agriculture.Read moreRead less
Nutritional ecology of free ranging herbivores. Australian grasslands underpin most of our livestock industries and provide important habitats for many native plants and animals. In order to manage these areas sustainably, farmers and other land managers need to know how much food animals consume and how the nutritional quality of that food varies. However there is no simple way of doing this and this prevents timely manipulation of stock numbers and limits our ability to predict fluctuations i ....Nutritional ecology of free ranging herbivores. Australian grasslands underpin most of our livestock industries and provide important habitats for many native plants and animals. In order to manage these areas sustainably, farmers and other land managers need to know how much food animals consume and how the nutritional quality of that food varies. However there is no simple way of doing this and this prevents timely manipulation of stock numbers and limits our ability to predict fluctuations in numbers of native herbivores such as kangaroos. The project will provide a cheap and quick means for ecologists and land managers to incorporate nutritional analyses into their work

Optimising the Strategy for Breeding Micronutrient-Dense Staple Foods that Improve Human health and Nutrition. The project is part of a new paradigm for agriculture in which staple crops are bred with greater micronutrient density to improve human health. It generates strategic basic information on how nutrients interact in the body of animal models in absorption, transport and utilisation that will allow plant breeders to optimise the breeding strategy for maximum outcomes in health and minimum ....Optimising the Strategy for Breeding Micronutrient-Dense Staple Foods that Improve Human health and Nutrition. The project is part of a new paradigm for agriculture in which staple crops are bred with greater micronutrient density to improve human health. It generates strategic basic information on how nutrients interact in the body of animal models in absorption, transport and utilisation that will allow plant breeders to optimise the breeding strategy for maximum outcomes in health and minimum breeding cost. Animals deficient in the nutrients of most concern (iron, zinc, vitamin A - and inulin) will be fed new varieties with enhanced levels of these factors, and from the responses, a superior strategy will be developed.Read moreRead less
