Synthesis of existing data on larval rock lobster distribution in southern Australia

Project number: 1996-107
Project Status:
Completed
Budget expenditure: $181,592.14
Principal Investigator: Barry Bruce
Organisation: CSIRO Oceans and Atmosphere Hobart
Project start/end date: 27 Oct 1996 - 14 Nov 2000

Objectives

1. To map the distribution of SRL larvae in southern Australia from existing plankton samples.
2. To hindcast interannual depth-dependent ocean circulation and hydrography during the period of larval availability.
3. To determine possible larval transport mechanisms and their implications for reproductive connectivity of management zones in the SRL fishery.
4. To examine the relationship between offshore ocean climate, distribution of phyllosoma and settlement of puerulus off eastern Tasmania (1992-1994 case study)

Implications of current spatial management measures on AFMA ERAs for habitats

In this project, CSIRO researchers implemented the first Australia-wide spatial approach to quantifying the exposure of mapped seabed assemblages to the footprints of Commonwealth demersal trawl fisheries, as well as their spatial protection in areas closed to trawling. These outputs are assisting...

Mapping the distribution and movement of gulper sharks, and developing a non-extractive monitoring technique, to mitigate the risk to the species within a multi-sector fishery region off southern and eastern Australia

This two year project provided the science to support the development of a management strategy for three gulper sharks species (genus Centrophorus) being assessed for threatened species listing. Their listing represented one of the most urgent environmental challenges to the South East Scalefish and...

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...

Variation in banana prawn catches at Weipa: a comprehensive regional study

Since about the year 2000 there have been very low catches in the Weipa Region of the Northern Prawn Fishery (NPF); these low catches were different to other areas of the NPF where they continued to fluctuate around long-term means and continued to fall within predicted levels. Industry and managers...
