Addressing urgent welfare concerns for Blackspotted Croaker (Protonibea diacanthus) populations in Queensland

Indicative Funding: $50,000
Summary: The Blackspotted Croaker (also known as black jewfish) is targeted by commercial, recreational, indigenous and charter fishing groups. Since 2017 there has been a rapid increase in targeted commercial fishing effort for Blackspotteed Croaker in Queensland. Given the high value of Blackspotteed Croaker, their vulnerability as aggregating species and the absence of a stock assessment to inform how many populations need to be managed, updated biological/ecological information (Including stock structure) are needed for assessment and protection of Blackspotted Croaker stock(s) in Queensland. The study aims at identifying stock structure and connectivity (including aggregation time) in order to improve management of th species across Queensland.

Indicative Funding: $29,033 over 2 years
Summary: The Project aims at assessing the effect of removing overhanging mangrove trees that have grown over artificially made channels over the last few decades. The mangrove pose a threat to the water flow, causing the drain to overfill during periods of heavy rainfall and flood the surrounding areas.

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.

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.
