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...
In Australia many stock assessments are dependent upon catch-per-unit-effort (CPUE) to act as an index of relative abundance of fished stocks through time. But CPUE trends can be affected by many factors other than just stock size changes. Around Australia, and internationally, numerous and...
Within the framework of the Commonwealth Harvest Strategy Policy, the Australian Fisheries Management Authority (AFMA) has adopted clear decision rules to set catch limits for commercially targeted species in Commonwealth fisheries. In several fisheries, AFMA has adopted a tiered harvest strategy...
The project reviewed the legislation dealing with Water Resource Management in each of Queensland, the Northern Territory, and Western Australia that effects the management of overland flow in catchments that empty into water managed as part of the Northern Prawn Fishery. The project...
Stock assessments provide scientific advice in support of fisheries decision making. They involve fitting population dynamics models to fishery and monitoring data to provide estimates of time-trajectories of biomass and fishing mortality in absolute terms and relative to biological reference...
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...
The management of abalone stocks is difficult for many reasons including their high value and the exceptional levels of spatial structuring found in their stocks. In Tasmania, for example, suggestions to change such things as a legal minimum length or introduce a formal harvest strategy to replace...
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 study undertook ecosystem and population modelling to evaluate and provide advice on the reference points (e.g. biomass depletion levels) and settings (e.g. exploitation rates) for the four main target species in the harvest strategy of the Commonwealth Small Pelagic Fishery (SPF) – Jack...
