Results have increased our confidence in the recruitment index based on the aerial survey in the Great Australian Bight (GAB) by confirming that the timing and duration are ideal, that the majority of juvenile SBT are likely to return to the GAB each summer, and that based on current evidence it is...
This report presents the results of the first application of Close-Kin Mark-Recapture (CKMR) using both Parent-Offspring Pairs (POP) and Half-sibling Pairs (HSP). This application to Southern Bluefin Tuna (SBT) has been successful, providing a decadal time series of absolute abundance, total...
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...
This project was a collaboration between CSIRO, the Australian Southern Bluefin Tuna Industry Association (ASBTIA) and the Australian Bureau of Meteorology (BoM). The project aim was to update work done as part of FRDC Project 2012/239 “Forecasting spatial distribution of Southern Bluefin Tuna...
A 3D primitive equation model has been developed for the Huon Estuary and D’Entrecasteaux Channel to examine the hydrodynamics of the region. Using a nesting process the region could be represented with high resolution while incorporating forcing due to wind stress, tides, low frequency sea...
