Linking fish recruitment and habitat use to ecosystem processes. Estuaries are transition zones between fresh and marine waters and form key nursery areas for fisheries. Understanding what makes an estuary a nursery area, and how dependent fish are on estuaries, is difficult because we lack vital information on fish recruitment and migrations. We will utilise chemical and genetic techniques to determine patterns of recruitment and migration of fish and link these patterns to biological character ....Linking fish recruitment and habitat use to ecosystem processes. Estuaries are transition zones between fresh and marine waters and form key nursery areas for fisheries. Understanding what makes an estuary a nursery area, and how dependent fish are on estuaries, is difficult because we lack vital information on fish recruitment and migrations. We will utilise chemical and genetic techniques to determine patterns of recruitment and migration of fish and link these patterns to biological characteristics of fish and physical variables of surrounding landscapes. Outcomes will provide managers with key landscape attributes than require conservation. Such information is vital for continued sustainability of fish and estuarine resources and will benefit rural coastal communities.Read moreRead less

Summary
Dual frequency identification SONAR (DIDSON) facility for sampling benthic and pelagic fish populations. Many Australians enjoy marine and freshwater resources, and we are exploiting fisheries and waterways in particular at an increasing rate. Effective management of fisheries requires understanding the abundance and behavior of fish. This facility will provide novel acoustic video technology for researchers to count fishes and sharks near weirs, under wharves or logs, and within seagrass beds. ....Dual frequency identification SONAR (DIDSON) facility for sampling benthic and pelagic fish populations. Many Australians enjoy marine and freshwater resources, and we are exploiting fisheries and waterways in particular at an increasing rate. Effective management of fisheries requires understanding the abundance and behavior of fish. This facility will provide novel acoustic video technology for researchers to count fishes and sharks near weirs, under wharves or logs, and within seagrass beds. The dual frequency identification sonar (DIDSON) will also allow accurate and standardised study of fish movements in response to floods, algal blooms or re-stocking events without disturbing the fish or their habitats. This will enhance our understanding of the top-down control by fish of aquatic ecosystems that are directly adjacent to human activity.Read moreRead less
Establishing an ecological basis for stocking density of Australian bass in freshwaters: Experimental field tests of a general numerical model. Large numbers of the Australian public go fishing, particularly in rivers and impoundments. Angling in these waterways provides a strong source of income for rural and regional communities. The stocking of native fish to support inland angling also sustains much of the aquaculture industry in western NSW and Queensland. This study will develop an optimal ....Establishing an ecological basis for stocking density of Australian bass in freshwaters: Experimental field tests of a general numerical model. Large numbers of the Australian public go fishing, particularly in rivers and impoundments. Angling in these waterways provides a strong source of income for rural and regional communities. The stocking of native fish to support inland angling also sustains much of the aquaculture industry in western NSW and Queensland. This study will develop an optimal approach to stocking Australian bass which is relevant for other stocked freshwater species, and will allow stocking to be undertaken in an environmentally responsible manner. This will both enhance the outcome of investment of public funds in stocking, and enhance the recreational fishing experience that is so important to rural regional communities.Read moreRead less
Fine-scale responses of freshwater fish to environmental flows in arid-zone rivers and wetlands. The community is demanding that river health be improved to sustainable levels through increased river flows. This will come through the efficient use of available environmental water that supports the ecology of Australia's river systems. This project will substantially inform the operational management of water for native fish populations and other organisms to specific wetlands and will guide the ....Fine-scale responses of freshwater fish to environmental flows in arid-zone rivers and wetlands. The community is demanding that river health be improved to sustainable levels through increased river flows. This will come through the efficient use of available environmental water that supports the ecology of Australia's river systems. This project will substantially inform the operational management of water for native fish populations and other organisms to specific wetlands and will guide the delivery of environmental flows to maintain native fish stocks. The project will help management of declining fish populations and more generally wetlands by improving our understanding of the role of environmental flows.Read moreRead less
Investigation of endocrine disruption in Australian aquatic environments. Water is a vital resource. The disposal of wastes is often associated with the release of contaminants like endocrine disruptors into the environment. These contaminants can impact the health of our waterways and lead to potential risks to fish populations and ultimately public health. The hazards resulting from endocrine disruptors have been well defined globally and to a lesser extent in Australia in the last decade, how ....Investigation of endocrine disruption in Australian aquatic environments. Water is a vital resource. The disposal of wastes is often associated with the release of contaminants like endocrine disruptors into the environment. These contaminants can impact the health of our waterways and lead to potential risks to fish populations and ultimately public health. The hazards resulting from endocrine disruptors have been well defined globally and to a lesser extent in Australia in the last decade, however we have very limited information about possible effects in Australian waterways or reservoirs. This research project will investigate the state of endocrine disruption in our waters. The knowledge gained will address this gap and provide a benefit to the national community, risk managers and importantly our waterways.Read moreRead less
Tracing Past and Present Pollution Sources in the River Torrens, South Australia. The Torrens River is the principal water supply to 500,000 South Australians. Since early in European settlement it has suffered the impacts of eutrophication and high rates of sedimentation. The Catchment Management Board is seeking to prioritise rehabilitation resources to maximise water quality improvements. This will be informed by the revelation of the principal sources of sediment and nutrients over time.
Planning for the adaptive management of wetland rehabilitation; Kanyapella Basin Case Study. Australia's ephemeral wetlands are being lost or degraded primarily through drainage. There is a pressing need to conserve the ecological character of remaining systems, and rehabilitate degraded ones. Rehabilitation is invariably constrained by water availability, community expectations and uncertainty about ecosystem responses to different water regimes. This project applies the adaptive management mod ....Planning for the adaptive management of wetland rehabilitation; Kanyapella Basin Case Study. Australia's ephemeral wetlands are being lost or degraded primarily through drainage. There is a pressing need to conserve the ecological character of remaining systems, and rehabilitate degraded ones. Rehabilitation is invariably constrained by water availability, community expectations and uncertainty about ecosystem responses to different water regimes. This project applies the adaptive management model to wetland rehabilitation. Adaptive management addresses uncertainty through experiments integrated into the rehabilitation process. It uses monitoring, and information feedback loops to inform current management actions. A generic model for the adaptive management of wetland rehabilitation will be developed which will predict responses to different re-wetting scenarios.Read moreRead less
