The Fish Theme of the Flow-MER program is evaluating the contribution of Commonwealth environmental water to fish population diversity and abundance across the Murray-Darling Basin. The research program includes two innovative projects:
Research Project F1: Fish population models to inform Commonwealth environmental watering.
Research Project F2: Flow, movement and fish population dynamics in the MDB.
Using existing field data, these projects will apply cutting-edge techniques including: population modelling, acoustic fish tracking data and otolith (i.e. earbones) microchemistry, to answer questions about where and why fish move, and how best to provide environmental water to support key life-history processes.
In this webinar video, we discuss fish population models and integrated analysis of fish movement data to illustrate river system connectivity. We explore two key questions:
- What is the contribution of Commonwealth environmental water to key native fish population processes, including movement, reproduction and survival at local and regional scales?
- How can this research inform environmental water delivery to enhance native fish populations?
Jason is a Fisheries Scientist with the NSW Department of Primary Industries and co-Project Leader for the Flows, Movement and Fish Population Dynamics research project. Jason’s current research program is focussed on the abiotic drivers of fish movement, spawning and recruitment within the Murray-Darling Basin, with a strong focus on riverine connectivity.
Brenton is the co-Project Leader for the Flows, Movement and Fish Population Dynamics research project, and a Principal Research Scientist with CSIRO. He has worked for 25 years on the ecology of freshwater and estuarine fish across south-eastern Australia, including flow-related ecology and population dynamics, habitat requirements, and fish movement and passage. He works closely with managers and the community to transfer knowledge and research outcomes to the conservation of freshwater ecosystems.
Charles is the Project Leader for FLOW-MER Population models project. He develops software to assist with managing native freshwater fish and created the Murray Cod management model, as well as undertaking a comprehensive scoping study for applying the template of the Murray Cod management model to other fish species in the MDB.
Ivor is the Theme Leader for the CEWO FLow-MER Fish Theme, and a freshwater fisheries biologist – with over 25 years industry experience in environmental flow planning, river management, fish passage and fish ecology. Ivor has worked in the tropical north, the semi-arid western rivers of NSW/Qld and in the temperate rivers of Victoria.
