Next-generation Close-kin Mark Recapture: using SNPs to identify half-sibling pairs in Southern Bluefin Tuna and estimate abundance, mortality and selectivity

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...

Putting potential environmental risk of Australia's trawl fisheries in landscape perspective: exposure of seabed assemblages to trawling, and inclusion in closures and reserves

This project implemented the first national spatial approach to quantifying the exposure of mapped seabed assemblages to the footprints of all demersal trawl fisheries that operate on the mainland continental shelf and slope of Australia, as well as their spatial protection in areas permanently...

Where do Calamari spawn in Northern Tasmania and how will this information aid the management of the Calamari fishery in Northern Tasmania?

This project has responded directly to management and industry concerns over a rapid increase in catch and effort on the Tasmanian north coast Southern Calamari fishery. The survey methodology applied in this project provided the evidence-base for implementing the first north coast Southern Calamari...

Sentinel sensors: revolutionising our understanding and management of the estuarine environment

This study, undertaken by CSIRO Oceans and Atmosphere, examines the usefulness of mussels as sentinels for environmental change using a novel biosensor. This project measured the vital signs of heart rate and behaviour in sentinel animals, as they respond to multiple and interacting changes in the...

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...

Aquatic Animal Health and Biosecurity Subprogram: Disinfection measures to support biosecurity for infectious spleen and kidney necrosis virus (ISKNV) at aquaculture facilities

Megalocytiviruses are a group of closely related viruses that cause mass mortalities in both marine and freshwater aquaculture. They are of global importance as they are listed by the World Animal Health Organization (OIE). They are difficult to control as they infect over 125 fish species and...

Aquatic Animal Health and Biosecurity Subprogram: Perkinsus olseni in abalone - development of fit-for-purpose tools to support its management

The project was able to successfully propagate a new P. olseni isolate from Queensland and successfully cultured the isolates from Spain, Japan, New Zealand, and South Australia as well as P. chesapeaki, which was used as a negative control. We were unable to culture the Western Australian (WA)...
