The influence of fish movement on regional fishery production and stock structure for South Australia's Snapper (Chrysophrys auratus) fishery

From 2007 onwards, South Australia’s snapper (Chrysophrys auratus) fishery underwent significant and unprecedented changes that impacted on the management of the fishery. This ultimately reflected our poor understanding of the movement behaviour of snapper and its consequences for...

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...

Developing a fishery independent estimate of biomass for snapper

This study was undertaken by the South Australia Research and Development Institute (SARDI). Through overcoming considerable technical challenges, this study was the first to successfully develop a relatively non-destructive molecular probe that can reliably identify Snapper (Chrysophrys auratus)...

Assessment of broad-scale exploitation rates and biomass estimates for the Tasmanian southern rock lobster fishery

Exploitation rate is an important fishery assessment parameter linking catch to legal-sized biomass, the portion of the stock available for harvest. Relative change in legal-sized biomass is a crucial performance indicator for the fishery as it measures the success of management...

Development of acoustic methods to survey orange roughy in the eastern and southern zones

Three acoustic surveys were carried out between 17 and 20 July 1996 on the orange roughy spawning ground off St. Helens, Tasmania. A combination of 22 demersal trawls and ensonification with three frequencies (12, 38 and 120 kHz) was used to assess the species composition around the spawning hill....

Grow-out of Snapper (Pagrus auratus) in sea cages

The aim of this project was to farm, on a pilot commercial scale, two indigenous species of marine fish: snapper, Pagrus auratus; and mulloway, Argyrosomus hololepidotus. The project involved: development of hatchery techniques; intensive rearing of larvae; transport of live fish; ...
