They are opportunistic omnivores, feeding on fish, crustaceans (particularly crabs, crayfish and shrimp), molluscs, worms and vegetation. Results and Discussion. Acanthopagrus butcheri is within the scope of WikiProject Australia, which aims to improve Wikipedia's coverage of Australia and Australia-related topics.If you would like to participate, visit the project page. "Variability in the location of the retinal ganglion cell area centralis is correlated with ontogenetic changes in feeding behavior in the black bream, acanthopagrus butcheri (Sparidae, Teleostei)." Acanthopagrus butcheri (Munro, 1949) is endemic to nearshore coastal areas, rivers and estuaries of south-ern Australia. Within each system they will typically reside around the upper estuary/lower rivers through summer months (generally in the vicinity of the salt wedge – brackish areas), and moving downstream with winter flows; following the salt wedge and with smaller individuals likely pushed downstream with higher flows. The two species are known to hybridise in some landlocked, coastal lakes in southern New South Wales. The two species look similar but can be distinguished by their colouration. They are absent from the Great Australian Bight region due to the lack of estuarine habitat there. However, recent research has demonstrated that reduced flows due to climate change and river regulation, and hypoxia, can result in reductions in the habitat availability and body condition of the species. Black Bream (Acanthopagrus butcheri) complete their whole lifecycle within an estuary and can cope with salinity and temperature changes that would kill many other species.As hardy as they are, they are still ultimately reliant on healthy rivers and estuaries for their survival. The southern black bream is endemic to southern Australia, inhabiting coastal waters from Shark Bay, Western Australia in the west to Mallacoota, Victoria in the east and south around the entire Tasmanian coastline.
