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...

Improve catch rate standardizations to account for changes in targeting

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...

Incorporating the effects of marine spatial closures in risk assessments and fisheries stock assessments

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...

Proposed northern Australia water developments pertinent to the Northern Prawn Fishery: collation and review

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...

Review and assess stock assessment methods used in Australia

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...

Developing innovative approaches to improve CPUE standardisation for Australia's multi-species pelagic longline fisheries

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...

Testing abalone empirical harvest strategies, for setting TACs and associated LMLs, that include the use of novel spatially explicit performance measures

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...

Estimating the abundance of School Shark in Australia using close kin genetic methods

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...

Review and update harvest strategy settings for the Commonwealth small pelagic fishery

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...
