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...
Based on the results of a comprehensive literature review and the collective expertise of the project team, we developed two alternative approaches with which to evaluate trade-offs between triple bottom line objectives and stakeholder preferences: a semi-quantitative multi-criteria decision...
This project was undertaken by a collaboration of senior fishery scientists at CSIRO and from New Zealand, together with a former fisheries manager now with the Commonwealth Department of Agriculture and Water Resources in Canberra, on the development of methods to construct indices of stock...
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...
Close kin mark recapture (CKMR) provides an estimate of absolute abundance that is independent of fishing behaviour. We present a first CKMR estimate of abundance for School Shark and discuss the management implications of our findings.
We found 65 half sibling pairs (HSPs), 3...
This project was a first attempt at estimating the total potential maximum sustainable yield (MSY) from Australia’s commercial fisheries. The project considered only key commercial species and selected by-product species. Estimating equilibrium MSY where there was a formal stock...
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...
