Goulburn: Oral History of John Koehn, John Douglas, and Roy Patterson


An interview with John Koehn, John Douglas, and Roy Patterson.

John Koehn is a research officer for the Arthur Rylah Institute, Melbourne, and studies freshwater fish ecology. John Douglas works for Victorian Fisheries, and Roy Patterson is a Taungurung man.

John Koehn talks about: his work recovering Catfish and Silver Perch populations in the Murray-Darling Basin, 2000; a commercial fishery that existed at Barren Box when Catfish abundant; drivers of Catfish decline; strengths and weakness of different fish species; impact of irrigation releases on water flow e.g. Murray River; impact of European carp on billabongs and lagoons; carp removal; importance of billabongs, floodplains, wetlands in the Murray-Darling system, their loss and degradation from human activities; importance of ‘active’ ecological management; geomorphology; importance of 'instability' in creating diverse habitats for fish species; changes in vegetation e.g. Phragmite (Common Reed).

The group add their diverse knowledge to the topics discussed, in particular the variety of Catfish species found across the Murray-Darling Basin.
