Measurement of stable isotope ratios of oxygen (18O:16O) and carbon (13C:12C) in the earstone (sagittal otolith) carbonate from assemblages of goldband snapper, Pristipomoides multidens, from waters off northern and western Australia revealed location-specific signatures and indicated that fish...

There are increasing demands for Australian fisheries management agencies to demonstrate that fisheries under their jurisdiction are being managed in accordance with the principles of ecologically sustainable development (ESD). The decision-making processes of the ESD management framework...
Catches of King George whiting in Victorian bays and inlets vary greatly from year to year. This research was aimed at finding out how much of this variation was due to the environment, and whether we could use measures of environmental variables to predict catches in the future. King George whiting...
The origins of many stocks of fish are unknown. As juveniles, many fish are found in estuarine regions. After a period in these habitats they may leave estuaries for coastal reefs and shelf waters where they may be commercially fished. Currently, we do not know the proportion of...
