Catch-at-age, age at first spawning, historical changes in growth, and natural mortality of SBT: an integrated study of key uncertainties in population biology and dynamics of SBT, based on direct estimates of age from otoliths

The CCSBT has recognized for a number of years that a better understanding of the population biology and demographics of southern bluefin tuna (SBT) is necessary for improved population modeling and stock assessments. In 1996, the CCSBT Scientific Committee identified three areas where our...

Definition of effective spawning stocks of commercial tiger prawns in the NPF and king prawns in the eastern king prawn fishery: behaviour of post-larval prawns

To effectively manage most fisheries, including penaeid prawn fisheries in northern and eastern Australia, it is important to know the relationship between the size of the spawning population and the number of young adults that recruit to a fishery in the next generation. In the tiger prawn fishery...

Growth, mortality, movements and nursery habitats of red-legged banana prawns (Penaeus indicus) in the Joseph Bonaparte Gulf

This project has contributed to the ecologically sustainable management of the Northern Prawn Fishery (NPF) by providing information on the status of red-legged banana prawn stocks and the nursery habitats that support this fishery. It has achieved these outcomes by firstly completing detailed...

Modelling to explore management strategies to optimise the value of the rock lobster fishery of Western Australia

The fishery for the western rock lobster (Panulirus cygnus) is Western Australia’s most important single species fishery, and yields an average annual catch of 10,500 to 11,000 tonnes valued at between $200 and $300 million at the point of landing. With a high level of exploitation and a...

Assessment of broad-scale exploitation rates and biomass estimates for the Tasmanian southern rock lobster fishery

Exploitation rate is an important fishery assessment parameter linking catch to legal-sized biomass, the portion of the stock available for harvest. Relative change in legal-sized biomass is a crucial performance indicator for the fishery as it measures the success of management...

Intensive cultivation of a calanoid copepod for live food in fish culture

The aim of this study was to develop a system for the cultivation of a calanoid copepod which occurs in estuaries in the southwest of Western Australia. This copepod, Gladioferens imparipes, seemed suitable for use in marine fish aquaculture; it can tolerate a wide salinity range, including sea...
