Biological and ecological research needed for the effective management of the bar-cheeked coral trout and the chinaman cod, including an investigation into the factors controlling sex-change in the serranids (cods, groupers and coral trout).

This study provides detailed biological and ecological information on the chinaman cod, Epinephelus rivulatus, and biological information on the bar-cheeked coral trout, Plectropomus maculatus, in West Australian waters. Both of these species are members of a large group of predatory fish known as...

Need

National reviews of Fisheries R&D needs (FRDC95/055) have identified the need for non-extractive, fishery-independent sampling and stock assessment techniques which are cost-effective, repeatable and robust across and range of habitats and depths. These methods are becoming increasingly important as Australian fisheries face the challenge of addressing ecosystem based fisheries management and climate change. A national workshop on the use of video for sensing the size and abundance of target and non-target fauna in Australian fisheries (FRDC2000/187) highlighted the potential for Baited Remote Underwater Video systems (BRUVs). After a decade, there has been wide adoption of this technique. However, differences in protocols for deployment, analysis and interpretation make spatial and temporal
comparisons of data difficult.

There is the need to develop a robust set of nationally agreed upon protocols to ensure that users are appropriately informed and trained through a comprehensive extension and capacity building program that also identifies key unresolved technical issues.

With the increased testing and use of BRUVs a number of independent developments have occurred. Future technological advances and more detailed statistical and modelling approaches will result in the BRUVs data being more useful for ecosystem assessment and management. Maximising the potential that these advances will provide to Australian fisheries will be achieved by a co-ordinated and
collaborative research strategy. We propose to host a two day workshop to critically evaluate the use of BRUVs as a data collection tool
for scalefishes and sharks. The workshop will identify the strengths, limitations and identify potential solutions.

Objectives

1. To critically evaluate the strengths and limitations of data collected with BRUVS for detecting changes in the relative abundance, length frequency and community composition of scalefishes and sharks.
2. To identify potential solutions to limitations.
3. To develop a nationally agreed to protocol for the deployment of BRUVs and the analysis of the resulting imagery.

Assess causes and implications of anomalous low lobster catch rates in the shallow water areas near the centre of the Western Rock Lobster fishery

Current and former West Coast Rock Lobster Managed Fishery (WCRLMF) fishers have anecdotally observed a trend of low catch rates since the 1990’s in the near-shore shallow water areas (<8 m) near the centre of the fishery (Dongara-Leeman). Since the atypically low puerulus counts of...

Optimising Compliance Outcomes in Recreational Fisheries

This study investigated strategies to enhance compliant participation among recreational fishers, using the Peel-Harvey Blue Swimmer Crab fishery in Western Australia (WA) and the Blue Swimmer Crab fishery in South Australia (SA) as case studies.

Behavioural and physiological studies on phyllosoma larvae of the Western Rock Lobster

The Western Rock Lobster (Panulirus cygnus George) is the most valuable single species fishery in Australia with an annual value in excess of $250 000 000. Consequently, there has been a substantial research effort geared towards gaining a better understanding of the basic biology of this species...
