Results will have broad applicability, as the critical environmental factors identif ....What drives recruitment variability in Snapper? Application of a novel theoretical and empirical approach to predict fluctuations in fisheries. This research will contribute to the sustainable management of the snapper resource to both protect the population and also provide long-term sustainability in terms of the ecosystem goods and services provided by the fishery, and associated social and economic benefits. Results will have broad applicability, as the critical environmental factors identified are likely to influence other species as well. Understanding the environmental factors underpinning recruitment variation in snapper will allow better predictions of impacts on recruitment levels resulting from climatic variability in the short term, and also longer-term effects of climate change on the population, for incorporation into future management assessments.Read moreRead less
Linking freshwater flows, salt wedge dynamics and fisheries productivity in estuaries. Freshwater is a critical resource in Australia, but there is a perception that freshwater running to the sea is wasted. Australia's estuaries are of great importance - economically, socially and environmentally. Estuaries provide habitat for unique and endangered animals and plants, support valuable fisheries, and have enormous recreational value, particularly in regional communities. Our lack of understanding ....Linking freshwater flows, salt wedge dynamics and fisheries productivity in estuaries. Freshwater is a critical resource in Australia, but there is a perception that freshwater running to the sea is wasted. Australia's estuaries are of great importance - economically, socially and environmentally. Estuaries provide habitat for unique and endangered animals and plants, support valuable fisheries, and have enormous recreational value, particularly in regional communities. Our lack of understanding about the effects of freshwater flows on estuarine productivity impedes decision making on the allocation of water to sustain healthy estuaries. The health of Australia's estuaries and sustainability of their resources, particularly fisheries, depend on understanding their freshwater requirements and securing environmental flows.Read moreRead less
Capture stress and post-capture survival of sharks and other chondrichthyans in fisheries bycatch. Australia is adopting ecosystem approaches to fisheries management. However, to embrace such an approach there is an urgent need for better information on the biology, ecology and population dynamics of sharks, rays and chimaeras (class Chondrichthyes). Chondrichthyan species are among the most sensitive in their response to the effects of fishing. Results from the present proposal will contribute ....Capture stress and post-capture survival of sharks and other chondrichthyans in fisheries bycatch. Australia is adopting ecosystem approaches to fisheries management. However, to embrace such an approach there is an urgent need for better information on the biology, ecology and population dynamics of sharks, rays and chimaeras (class Chondrichthyes). Chondrichthyan species are among the most sensitive in their response to the effects of fishing. Results from the present proposal will contribute to determining mortality of chondrichthyan bycatch species in response to the effects of capture in fishing gear, handling by fishers and discarding at sea. The work will contribute to biodiversity conservation and maintenance of ecosystem structure and function for present and future generations.Read moreRead less
Automation of species recognition and size measurement of fish from underwater stereo-video imagery. The project aims to develop algorithms to automate the processing of stereo-video images recorded to count and measure the size of fish. This will improve husbandry and monitoring for finfish aquaculture at reduced costs, create technology export for industry partners, and develop cost effective, non-destructive finfish sampling tools for marine agencies.
Molecular biosignatures for isolating pollution problems in aquatic ecosystems using macroinvertebrate bioindicators. Aquatic ecosystems are under increasing threat by human activities. This has been further exacerbated by drought and climate change. In the future, understanding the major factors impairing aquatic ecosystems will be a vital part of sustaining water resources. This project develops new molecular tools to better monitor and assess aquatic pollution. We will develop a new high-tech ....Molecular biosignatures for isolating pollution problems in aquatic ecosystems using macroinvertebrate bioindicators. Aquatic ecosystems are under increasing threat by human activities. This has been further exacerbated by drought and climate change. In the future, understanding the major factors impairing aquatic ecosystems will be a vital part of sustaining water resources. This project develops new molecular tools to better monitor and assess aquatic pollution. We will develop a new high-tech deoxyribonucleic acid (DNA) approach to identify insect indicator species and combine this with a field-based microcosm method that uses local aquatic insects to isolate pollution effects from other impacts. This proposal will facilitate fast identification of pollution problems and provide the water industry with an innovative means to assess pollution and monitor remedial actions.Read moreRead less

Does Emotional Intelligence predict final year academic results and student retention in secondary schools? Over the past 30 years the completion of the final year of secondary school education has become increasingly important, with a shift towards the requirement of higher levels of education throughout the Australian labour market. As a consequence, early school leavers are three times more likely to be unemployed than those students that complete Year 12 or post-secondary education. The pro ....Does Emotional Intelligence predict final year academic results and student retention in secondary schools? Over the past 30 years the completion of the final year of secondary school education has become increasingly important, with a shift towards the requirement of higher levels of education throughout the Australian labour market. As a consequence, early school leavers are three times more likely to be unemployed than those students that complete Year 12 or post-secondary education. The proposed study will examine the role of emotional intelligence (EI) in academic performance at Year 12 and school retention in secondary schools. The results of the study will help schools develop evidence-based strategies to best retain students and help students maximise their academic potential.Read moreRead less
