Development of biological tagging techniques for penaeid prawns

The objective of this project was to develop novel biological tags for penaeid prawns. The impetus for this research was the growing interest in Australia in the potential for stock-enhancement of penaeid fisheries with hatchery reared juveniles. In any stock- enhancement program some...

Determination of the spatial dynamics and movement rates of the principal target species within the Eastern Tuna and Billfish Fishery and connectivity with the broader western and central Pacific Ocean – beyond tagging

Accessing samples from broadbill swordfish from two sites within the WCPFC area was particularly problematic and was exacerbated by a poor fishing season in 2019. This resulted in samples for broadbill swordfish consisting of samples collected from the ETBF (2 years), Norfolk Island (1 year) and New...

Spatial interactions among juvenile southern bluefin tuna at the global scale: a large scale archival tag experiment

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...

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...

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...

Forecasting spatial distribution of Southern Bluefin Tuna habitat in the Great Australian Bight – updating and improving habitat and forecast models

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...
