Black Bream (Acanthopagrus butcheri) are an important commercial and recreational fish species in the Vasse Wonnerup wetlands and have been severely impacted by major fish kills. As a long-lived fish species that spend their entire life in the wetlands the Black Bream are an important indicator of fish health.
Two indicators were developed for Black Bream, one measuring recruitment of juvenile fish and the other body condition of adult fish. Fish monitoring undertaken in spring and summer in the Wonnerup Inlet and Deadwater is used to calculate the indicators following methodology developed by Murdoch University.
