Native fish stocking of rivers: discriminating between hatchery-reared and wild fish. Stocking of fish is widely used in attempts to restore native fish populations. Little is known of the fate of stocked fish or the effects of stocking on resident populations. We will develop and evaluate protocols for chemical marking of otoliths of hatchery-reared fish so that their source can be determined. Experimental stocking of hatchery-reared fish will be undertaken and population structure and sourc ....Native fish stocking of rivers: discriminating between hatchery-reared and wild fish. Stocking of fish is widely used in attempts to restore native fish populations. Little is known of the fate of stocked fish or the effects of stocking on resident populations. We will develop and evaluate protocols for chemical marking of otoliths of hatchery-reared fish so that their source can be determined. Experimental stocking of hatchery-reared fish will be undertaken and population structure and source of stocked versus wild fish determined in stocked and unstocked rivers. Natural chemical signatures will also help determine important recruitment areas. The outcomes will allow fisheries managers to make informed decisions regarding stocking strategies.Read moreRead less

This project signals the start of exciting new research using manned submersibles to explore and describe the rich biodiversity inhabiting Australia’s deep-sea continental shelf. The outcomes will provide a sound basis for managing these environmental treasures against the pressing need to use the oil and gas reserves that lie under the seabed.
Assessing the benefits of closed fishing areas for spawning aggregations and egg production for coral trout. Coral trout is a valuable finfish species that inhabits coral reef systems in Australia. Like most other finfish species, coral trout is managed mainly through catch and size limits. However, closed fishing areas also provide a degree of protection from exploitation. Worldwide, closed fishing areas have been shown to provide larger and more fish within their boundaries. At present, there ....Assessing the benefits of closed fishing areas for spawning aggregations and egg production for coral trout. Coral trout is a valuable finfish species that inhabits coral reef systems in Australia. Like most other finfish species, coral trout is managed mainly through catch and size limits. However, closed fishing areas also provide a degree of protection from exploitation. Worldwide, closed fishing areas have been shown to provide larger and more fish within their boundaries. At present, there are limited empirical data to show that they provide benefits to fish stocks. This project aims to examine whether closed fishing areas provide a benefit to coral trout at the Abrolhos Islands, Western Australia.Read moreRead less

Conservation ecology of the black cod (Epinephelus daemelii). Black cod is a large, reef fish species that was once common and commercially important in NSW. Today, Black Cod is listed as vulnerable, and we know little more of their biology than when they were first protected in 1983. This project will significantly increase the effectiveness of Black cod management by determining their distribution, abundance, stock structure, fecundity, spawning behaviour and recruitment. This will allow imple ....Conservation ecology of the black cod (Epinephelus daemelii). Black cod is a large, reef fish species that was once common and commercially important in NSW. Today, Black Cod is listed as vulnerable, and we know little more of their biology than when they were first protected in 1983. This project will significantly increase the effectiveness of Black cod management by determining their distribution, abundance, stock structure, fecundity, spawning behaviour and recruitment. This will allow implementation of an effective recovery plan and a review of the status of Black Cod internationally and by the Federal Government. Collaboration with NSW Fisheries' Grey Nurse Shark program will allow assessment of the importance of Grey Nurse critical habitat areas in maintaining Black Cod populations.Read moreRead less
Functional-trait approach to restoration of species-rich shrublands. The project aims to deliver management tools that will help mining companies to meet restoration targets and to improve the field of trait-based predictive restoration ecology. Species-rich kwongan shrublands of south-west Australia are a biodiversity treasure. Despite their global and national conservation value, little is known about which plant traits are most important for community assembly and diversity maintenance. This ....Functional-trait approach to restoration of species-rich shrublands. The project aims to deliver management tools that will help mining companies to meet restoration targets and to improve the field of trait-based predictive restoration ecology. Species-rich kwongan shrublands of south-west Australia are a biodiversity treasure. Despite their global and national conservation value, little is known about which plant traits are most important for community assembly and diversity maintenance. This project plans to use plant functional traits related to nutrient and water acquisition to predict plant community assembly under different soil resource availabilities and thus assist in successful rehabilitation of this native vegetation after closure of sand-mining operations.Read moreRead less
Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si a ....Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si alleviates stress in wheat, from gene to farm scale, providing cost-benefit analysis and a best–practice toolbox for implementation by farmers. Outcomes are anticipated to provide a cheaper and more environmentally sustainable solution to issues of water scarcity and yield losses to pests in Australia’s leading crop.Read moreRead less
