Influence of the Camballin Barrage on Fish Communities in the Fitzroy River, Western Australia

The Barrage on the Fitzroy River presents a considerable barrier to fish migrations in this ecologically, culturally and socially important system.

Water regime dependence of fish in the wet-dry tropics

This project has improved understanding of the potential ecological impacts of changes in dry season flow regimes of tropical river ecosystems caused by water resources development in these catchments. The project investigated variation in fish distribution and ecological requirements across a natural flow regime gradient using field sites, and document indigenous knowledge on fish in the Daly River. This information has been used to develop models, based on BBNs, to predict the impact of different (more)...

Targeting endocrine disruptors in Australia's waterways

When the media reported the intriguing story of ‘gender bending’ chemicals causing fish in UK streams to develop male and female sex organs, research teams began to investigate the cause. The gender benders, actually endocrine disrupting chemicals (EDCs), were mainly natural and man-made hormones excreted by humans, and some industrial chemicals. Even in trace amounts, the EDCs alter levels of hormones and specific proteins. This in turn causes intersex (both (more)...

Review of alien fish monitoring techniques, indicators and protocols

Implications for national monitoring of Australia’s inland river systems

This report is an advisory document that has been commissioned by the National Land and Water Resources Audit (NLWRA) and prepared by the Invasive Animals Cooperative Research Centre. The report, Review of Alien Fish Monitoring Techniques, Indicators and Protocols: Implications for National Monitoring of Australia’s Inland River Systems, is not intended to be an exhaustive review. It brings together fundamental information regarding alien fish to inform (more)...

Ecological risk associated with irrigation in the Goulburn Broken

Stage 2: GMW11 Final Report

During Phase I of the project “Assessment of Ecological Risk Associated with Irrigation Systems in the Goulburn Broken Catchment” (Cottingham et al., 2001) adverse changes to the abundance and diversity of native fish and the occurrence of cyanobacterial (or blue-green algal) blooms were identified as priority ecological issues to be further investigated in Phase II of the project. Investigations have now been carried out to further assess the risks associated with (more)...

Assessment of the ecological risks associated with irrigation in the Ord River Catchment

Phase 1 - Identification of risks and development of conceptual models

The purpose of this project is, as part of a larger NPIRD project, to identify potential ecological risks associated with irrigation systems in the Lower Ord River catchment. Specifically the objectives of this project are to: Develop a list of up to six ecological consequences of development in the catchment where irrigation is likely to have a significant impact. This is to done in consultation with relevant catchment stakeholders, identified by (more)...
