Assessing the roles of batoids in coastal sandflats

Indicative Funding
$6,750
Summary
This project will develop and implement innovative data collection methods using drone technology to assess the roles of batoids in coastal sandflats. Specifically, we will be developing methods to map the locations of batoid feeding pits, calculate the volume of sediment turned over, and gain detailed behavioural observations. Results from this research will highlight the important roles batoids play in coastal sandflats and provide a useful tool for assessing the foraging impacts of batoids on sandflats that can be applied on a global scale. Additionally, we will determine if feeding pit counts can be used to estimate the abundance of batoids on a sandflat. If successful, this technique has broad application potential for monitoring batoid populations which will be vital for their conservation.

Developing Best Fishing Practices for Fish Welfare and Conservation: Evaluating Stress and Survivorship of Recreational Fish Species

Indicative Funding
$294,000 over 2 years
Summary
Sport fishing is one of the largest recreational activities worldwide. An important component in ensuring sustainable recreational fisheries is promoting ethical catch and release practices. This means it is important to understand the effects of capture and handling recreationally caught fish, so that the best fishing/handling practices can be developed. This project will measure the stress levels from the capture event, quantify post-release survival of key tropical recreational fish species, and use obtained information to develop best-practice guidelines to improve the survivorship and welfare of released fish. Results will be useful to inform a better management of fish stocks.

Identification and Restoration of Intertidal Fish Nursery Habitat in the Baffle Catchment

Indicative Funding
$266,456 over 2 years
Summary
This project aims to identify high intertidal fish nursery habitat pools in the Baffle Drainage Basin (BDB), assess their value to fish, evaluate the current state of their functionality, prioritise pools for restoration and identify viable restoration solutions. By involving local stakeholders, local government, regional NRM and State Government scientists and managers, a network of users will gain an understanding of how these habitats function and can be restored, based upon this baseline research.

Dissolved oxygen as a constraint for fish utilising mangrove forests.

Indicative Funding
$3,750
Summary
This project focuses on understanding how dissolved oxygen (DO) impacts mangrove fish utilisation. In heavily vegetated habitats like mangroves, DO undergoes complex changes brought about by biogeochemical demand. The extent of DO depletion depends on many environmental parameters such as tide, time or day or human activities. Substantial DO depletion could limit the value of mangroves as habitats for fish. Consequently, I aim to: (i) develop an understanding of DO dynamics in mangrove forests; (ii) identify environmental parameters that drive these fluctuations; (iii) investigate how depressed DO impacts fish assemblages and behaviour; and (iv) establish DO thresholds for five fish species occupying mangroves.

Ecological valuation tools to protect seagrass during coastal development

Indicative Funding
$490,000 over 4 years, in partnership with the Gladstone Ports Corporation Ltd ($450,000 over 3 yrs)
Summary
Seagrasses provide ecosystem services (fisheries, nutrient cycling, primary productivity) worth trillions of dollars, but this capacity is threatened by coastal development. In Australia, port developments are considered a major threat to seagrass ecosystems, but resource managers lack accurate information about their potential impacts and mitigation measures. Focussing on differences between shallow and deep seagrasses within the Great Barrier Reef, this project seeks to develop a world-first spatial valuation tool that will allow resource managers and policy makers to minimise impact of port development on seagrass ecosystems, thereby ensuring that Australia?s seagrasses continue to provide ecosystem services essential to our well-being.

Roles of batoids in coastal and reef ecosystems: impacts on predator and prey populations and the potential for energy transfer to adjacent subtidal and offshore communities

Indicative Funding
$25,450 over 2 years
Summary
This study will determine 1) the species composition, abundance, and biomass of batoid fauna in coastal sandflats and reef habitats, 2) the proportion of time different batoid fauna spend in intertidal versus subtidal zones, 3) the ecological importance of batoid utilization of intertidal habitats, and 4) how the above differ between sandflat and reef habitats. Results will contribute to understanding batoid community structure in different habitats and aid in identifying preferred habitat types throughout the year. In addition, understanding the ecological role of batoids in different habitats will stress the need for conservation of these species and development of more effective management strategies to mitigate catches in commercial fisheries.

Australian Acoustic Observatory: A Network to Monitor Biodiversity

Indicative Funding
$900,000 (administered by QUT)
Summary
Acoustic sensing is transforming environmental science by recording vocal species 24 x 7, providing data of unparalleled spatial and temporal resolution for ecosystem monitoring and research. This is particularly relevant to Australia's fragile and mega-diverse environment and Australia has leading research expertise in this emerging field. The proposed observatory will be the world's largest terrestrial acoustic sensor network comprising 450 listening stations deployed across Australia. Funds will purchase autonomous sound recorders and online storage and processing hardware. Data will be freely available to all online, enabling new science in understanding ecosystems, long-term environmental change, data visualisation and acoustic science.

The Infinite Turtle Project

Indicative Funding
$80,000
Summary
There is currently no consolidated program to provide the resources and training to turtle welfare volunteer groups and indigenous rangers along the Queensland coast. The proposed 'Infinite Turtle Project' will (i) establish an online forum for groups to register for information; (ii) provide online training material for turtle rescue response, nesting monitoring, and hatchling monitoring; and (iii) provide feedback and linkages with appropriate local government and wildlife carers to build better and ongoing communication. This program will be established over one year but will have long term benefits of increased sea turtle success and continual data exchange and training.
