Development of a sustainable industry-based observation system for blue grenadier at the primary spawning sites

Blue grenadier has the highest current TAC among SEF species and has two separate fisheries that target primarily either sub-adult fish year-round or mature adults in winter spawning aggregations. The sustainability of the fishery would be greatly enhanced with regular (sustained) monitoring of...

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...

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...

Quantitative interpretation of fine-scale SBT catch per unit effort for south east Australia

An analysis of spatial and temporal variations in catch rates of Southern Bluefin Tuna (SBT) in relation to environmental factors was conducted for the region south of Tasmania up to 1he southern half of New South Wales. Substantial temporal and spatial variations were evident in...

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...

Seamount fauna off southern Tasmania: impacts of trawling; conservation and role within the fishery ecosystem

In September 1995, the deepwater trawl fishing industry agreed not to trawl in an area of 370 km2 on the continental slope south of Tasmania for three years, as stated in a Memorandum of Understanding between the former Australian Nature Conservation Agency (now Environment Australia) (EA) and the...
