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...

Objectives

1. To identify pupping and nursery grounds for school and gummy sharks in southern Australia
2. Determine the distribution size structure duration time and movements of newborn and juvenile sharks in nursery areas
3. Attempt to develop recruitment indices for school and gummy sharks
4. Determine pre-recruit mortality from tagging experiments
5. Determine relative catch rates of juveniles by commercial and recreational fishers

Evaluation of selectivity in the south-east fishery to determine its sustainable aggregate yield

Project number: 1996-140
Project Status:
Completed
Budget expenditure: $103,407.00
Principal Investigator: Nicholas Bax
Organisation: CSIRO Oceans and Atmosphere Hobart
Project start/end date: 8 Aug 1996 - 14 Jan 2005
Contact:
FRDC

Objectives

1. Determine size(age) at capture for the main commercial species in the SEF that would maximise their biologic and economic yield, especially for the quota species.
2. Determine selectivity of the major fisheries in the SEF, taking account of the mix of gear types and the areas fished.
3. Evaluate success of alternative gear mixes (type and configuration) in maximising overall biologic and economic yield for selected fisheries.
4. Identify fisheries that contain mixes of gear types and species that lead to a grossly undesirable selectivity of some species, and that could profit from the development of specialised selective techniques
5. Help to coordinate and present results at SEFAG workshop to assess the potential of adapting selectivity of the SEF to promote sustainabilty and economic returns.

Development of the aquaculture capability of the brown tiger prawn (Penaeus esculentus)

In order to provide for future growth of the Australian prawn aquaculture industry, there is a need to take a longer-term strategic view and develop production technology for alternative species that can support an export market but do not have the intense overseas competition of the current major...
