The role of neurohormones in the regulation of appetite and successful sea water transfer in farmed Atlantic salmon. Cultured Atlantic salmon spend the first part of their life in freshwater and then following a physiological adaption phase called smoltification, the fish (now termed smolts) are transferred to sea cages for growout. A proportion of smolts fail to thrive after transfer, show slow or no growth and usually die some months later. This project will investigate the role that the neuro ....The role of neurohormones in the regulation of appetite and successful sea water transfer in farmed Atlantic salmon. Cultured Atlantic salmon spend the first part of their life in freshwater and then following a physiological adaption phase called smoltification, the fish (now termed smolts) are transferred to sea cages for growout. A proportion of smolts fail to thrive after transfer, show slow or no growth and usually die some months later. This project will investigate the role that the neurohomones that control both appetite and physiological stress in fish have in stimulating the resumption of feeding after sea water transfer.The basic knowledge generated will be used directly in development of strategies for minimising smolt failure in Atlantic salmon aquaculture.Read moreRead less
The cellular basis of temperature impairment of reproductive function in Atlantic salmon. Elevated summer and autumn temperatures, either as a result of normal climate variation or global warming, inhibit reproduction in salmonid fishes by disrupting endocrine (hormonal processes). The mechanisms involved are unclear but are known to involve inhibition of ovarian estrogen and the assembly of egg-yolk proteins. This project will investigate the cellular basis of the inhibitory effect of high temp ....The cellular basis of temperature impairment of reproductive function in Atlantic salmon. Elevated summer and autumn temperatures, either as a result of normal climate variation or global warming, inhibit reproduction in salmonid fishes by disrupting endocrine (hormonal processes). The mechanisms involved are unclear but are known to involve inhibition of ovarian estrogen and the assembly of egg-yolk proteins. This project will investigate the cellular basis of the inhibitory effect of high temperature on reproduction, at the ovarian and hepatic levels. The understanding developed will be an essential component of amelioration strategies for managing the continued successful rearing of salmon and trout under warming environmental conditions.Read moreRead less

Summary
Research Network for Biotechnological and Environmental Applications of Microalgae (BEAM). The network will facilitate inderdisciplinary and collaborative research into the limitations on microalgal growth leading to the development of new, commercial-scale microalgae culture systems, the production of fine chemicals, bioactive compounds and renewable fuels (hydrogen), as well as environmental applications such as monitoring the physiological state of phytoplankton in the environment, CO2 biorem ....Research Network for Biotechnological and Environmental Applications of Microalgae (BEAM). The network will facilitate inderdisciplinary and collaborative research into the limitations on microalgal growth leading to the development of new, commercial-scale microalgae culture systems, the production of fine chemicals, bioactive compounds and renewable fuels (hydrogen), as well as environmental applications such as monitoring the physiological state of phytoplankton in the environment, CO2 bioremediation and algal/bacterial systems for the bioremediation of contaminated soils. This will be achieved by applying research on photosynthetic light utilisation efficiency and carbon fixation, chlorophyll fluorescence, biochemistry of secondary metabolites, molecular biology and photobioreactor design and engineering, informed by an understanding of the ecology of these algae.Read moreRead less
The impact of environmental change on larval energetics of molluscs on the southeast coast of Australia. This project will investigate the impact of environmental change on larval energetics of molluscs on the southeast (SE) coast of Australia. The SE coast of Australia is a climate hotspot characterised by rising ocean temperatures, fluctuations in salinity and we expect in the near future ocean acidification (OA). Mollusc larvae show extreme sensitivity to OA, but the impacts of other stressor ....The impact of environmental change on larval energetics of molluscs on the southeast coast of Australia. This project will investigate the impact of environmental change on larval energetics of molluscs on the southeast (SE) coast of Australia. The SE coast of Australia is a climate hotspot characterised by rising ocean temperatures, fluctuations in salinity and we expect in the near future ocean acidification (OA). Mollusc larvae show extreme sensitivity to OA, but the impacts of other stressors remains unknown. It is predicted that OA will reduce the capacity of larvae to cope with temperature and salinity, particularly when food supply is low and in populations which have had no previous exposure to OA. Understanding the response of mollusc larvae to environmental change will support ecologically and economically significant mollusc populations over this century.Read moreRead less
