A Charles Sturt University (CSU) researcher who is investigating the long term sustainability of the iconic Murray crayfish in NSW and Victoria will present a talk at the Wonga Wetlands on the Murray River near Albury on Friday 3 October. Ms Sylvia Zukowski will speak about the habitat, diet, location and possible reasons for the declining population of the crayfish. The second largest fresh water crayfish in the world (after the Tasmanian crayfish), it lives in the Murray and Murrumbidgee rivers and their tributaries, but is no longer found downstream from Mildura. Sylvia is completing a PhD on the ecological and social impacts of fresh water fishing regulations on Murray crayfish, through CSU’s Institute for Land, Water and Society and is supervised by well known aquatic scientist Associate Professor Robyn Watts and social researcher Professor Allan Curtis.
