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...

Use of archival tags for studying the movement and swimming behaviour of school sharks

There has been serious concern over the status of the school shark fishery for many years, and it has been the subject of numerous stock assessments (Punt & Walker 1998). It is a well researched species: Olsen (1954) showed that school shark can make extensive migrations, and that females moved...

The direct estimation of age and growth of SBT

This project was developed in response to calls from the SBT Trilateral (now the CCSBT) Scientific Committee for the development and validation of techniques for the direct estimation of age and growth in the species. Since the early 1980’s, the stock assessment methods used by...
