Freshwater flow requirements of estuarine – dependent Fisheries – data review and research needs

Conceptual models of the likely impacts of freshwater flows have been developed for seven species or species complexes that are regularly caught in the commercial and recreational fisheries of the Gulf of Carpentaria and reviewed by researchers with experience in the Gulf of Carpentaria. These conceptual models have been used to develop a range of research that could potentially elucidate the linkages between the importance of freshwater flows and fisheries production.

Fishes of the King Edward and Carson Rivers

with their Belaa and Ngarinyin names

The results of this study have revealed that the number of freshwater fishes (species diversity) of the King Edward River is higher than has previously been recorded for a Western Australian river. Twenty-six freshwater fish species were recorded, which is three species higher than the much larger Fitzroy River in the southern Kimberley. The study also resulted in a number of range extensions, including Butler’s Grunter and Silver Cobbler to the west, and the Slender Gudgeon to the north and east. (more)...

Environmental Water Allocation required to sustain macroinvertebrate species in ephemeral streams

Project Objectives: To determine the key drought refuges used by macroinvertebrate species in intermittently-flowing streams and determine the level of threat to each refuge posed by prolonged drying and unpredictable flow regimes To determine the role played by different types of drought refuge in restocking macroinvertebrate populations in rivers and therefore the consequences for river communities of loss of each type of drought refuge. To determine the (more)...

Water allocation to River Murray wetlands: a basin-wide modeling approach

The primary aim of this project was to relate the water regime preferences of wetland plants to hydrology throughout the Murray River Basin and to predict the volume of additional water required to achieve optimal plant species diversity. This report details the methods and key findings of the project which examined the impact of regulation and changes in water allocation on the community composition of wetland plants through the Murray River basin. Due to a lack of primary data, it deals (more)...

Best practice for on-ground property weed detection

Weedy species will continue to enter Australia while existing species expand their range via various pathways of weed spread (the subject of Defeating the Weed Menace Project UNE61, Pathway Risk Analysis for Weed Spread within Australia).

Effect of land use and peri-urban development on aquatic weeds

The primary objective of the proposed work was to understand the impacts of peri-urban development on aquatic weed invasions. We quantified aquatic weed abundance according to land use through desktop and field-based surveys and classified 24 species in a…
