Originally from Mozambique, Kátya is an aquatic ecologist with experience working in rivers and estuaries of Australia, East Africa and the Pacific Islands. Her research is mostly related to the identification and quantification of impacts of different human activities (e.g. urbanization, deforestation, flow regulation, agriculture, introduction of exotic species) on the aquatic ecology. She also works on animal movement, particularly in questions related to migration patterns and habitat use of bony fish and sharks; to the identification of critical habitats for fisheries species so that the best habitats to protect, preserve or restore can be identified; and to the development of fisheries best practices.

Determining population structure and connectivity of elephant fish stocks in southern Australia
- Indicative Funding
- $24,000 over 2 years
- Summary
- Elephant fish reproductive aggregations are targets of commercial and recreational fisheries. Although stock structure is unkown, Australian populations are currently treated as a single stock by management. A recent study revealed limited movement between different fishing zones (Tasmania and Bass Strait), suggesting limited connectivity between regionals. However, some individuals moved between zones, making it difficult to draw conclusions about broader stock structure and genetic connectivity. In addition, elephant fish may comprise >1 species, as there seems to be different morphologies between Australian and New Zealand fish. This project studies the genetic connectivity of elephant fish across thei8r range to identify the number of populations and possible cryptic speciation, and the mechanisms driving these patterns.

Assessing the roles of batoids in coastal sandflats
- Indicative Funding
- $6,750 over 1 year
- 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 3 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.

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 3 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.
