Key research

  • Collation and synthesis of dietary data for fish in marine and estuarine waters of south-western Australia.
  • Serene Ang and Elaine Lek - Addressing current gaps in dietary knowledge for important fish species, such as tarwhine (Rhabdosargus sarba), western yellowfin bream (Acanthopagrus latus), dhufish (Glaucosoma hebraicum) and tuskfish species on the lower and central west coasts of WA.
  • Development of sophisticated approaches in order to understand the relationships between fish and their potential prey.
  • Thea Linke - Development of biochemical techniques to determine trophic relationships of fish.
  • Elaine Lek - Diet studies of three co-occurring labrids in Jurien Bay.
  • Emma Sommerville - Diets of elasmobranchs.
