Research into how native fish move through river systems, specifically factors that affect how fish larvae swim, is underway at Charles Sturt University (CSU) in Albury-Wodonga. CSU fish ecologist, Dr Paul Humphries, is working with Associate Professor Hubert Keckeis, from the University of Vienna in Austria, to discover how native fish survive in Australian rivers. “As rivers in the Murray Darling Basin come under greater pressure due to drought, climate change and diminishing water resources, we need to learn more about how native freshwater fish such as the iconic Murray Cod survive and what we can do to help them,” Dr Humphries said. “This has major implications for the health of rivers in the Basin and the recreational fishing carried out in them.” This week is National Native Fish Week. Professor Keckeis is visiting CSU to learn techniques developed in Australia for use in the rehabilitation of the giant Danube River that runs across southern Europe, including his native Austria.
