Research interests

  • Freshwater and estuarine fish ecology
  • Fish passage and migration in relation to barriers and flow
  • Acoustic telemetry
  • Otolith microchemistry
  • Stable isotope analysis


Chris is a fish ecologist based at the Batemans Bay Fisheries Centre where he leads a variety of projects monitoring and mitigating the impacts of water regulation on freshwater and estuarine ecosystems. Much of his science is interdisciplinary, using a suite of modern research techniques including acoustic and Passive Integrated Transponder (PIT) telemetry, Stable Isotope Analysis and otolith microchemistry in an attempt to improve the design and operation of river infrastructure for fish migration. Recent research projects have included assessing the effectiveness of coastal fishways in providing successful upstream and downstream fish passage. He currently supervises a number of post graduate students at various universities.
