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...

Population dynamics and management of spanner crabs in southern Queensland

Spanner crabs (Ranina ranina) represent a valuable resource to southern Queensland and northern NSW. The fishery became established in the late 1970s, and as a result of an almost exponential increase in fishing effort between 1992 and 1995 an output-controlled limited entry management arrangement...

Mortality, growth and movements of the western rock lobster, Panulirus cygnus

The very high levels of exploitation in the western rock lobster fishery have resulted in the introduction of regional or zone-specific management arrangements in recent years. This is a permanent departure from an holistic approach to the fishery’s regulation. A detailed knowledge of...

Condition and its assessment in the southern rock lobster (Jasus edwardsii). Assessment of condition indices and moult staging techniques

In July 1993, a program was initiated by the South Australian Research and Development Institute (SARDI) and the South Australian Rock Lobster Research Association (SARLRA) to study the population dynamics of the Southern Rock Lobster. The study fitted with, and became part of, the tri-state...

The impact of changes in fishing patterns on red-legged banana prawns (Penaeus indicus) in the Joseph Bonaparte Gulf

The fishery for red-legged banana prawns in the Joseph Bonaparte Gulf (JBG) developed in the early 1980s. Since then, fishing effort has varied from 700 to 2600 boat-days per year and catches range from 200 to 1000 tonnes per year. Initially the JBG fishery developed as an alternative to fishing in...

Estimation of population parameters for Australian prawn fisheries

One of the main objectives of fisheries management is to ensure the sustainability of fished stocks. To reach this objective scientists have to adequately assess the status of fished populations with quantitative models of the fishery systems. Most of these models require estimates of population...

Indices of recruitment and effective spawning for tiger prawns stocks in the Northern Prawn Fishery

In the mid to late 1980s NORMAC began to suspect that tiger prawn spawning stocks in the NPF may have been reduced by fishing to levels that reduced recruitment to the fishery. A vessel buy-back scheme and other effort reductions were introduced to reverse this trend but, by the mid-1990s, the...

Development of an integrated fisheries management model for King George whiting (Sillaginodes punctata) in South Australia

The King George Whiting Simulator (WhitSim) is a simulation version of the Whiting Estimator (WhitEst) encased inside a graphical user interface (GUI) that includes geographical information systems (GIS). WhitSim provides the ability to simulate various management strategies and parameter scenarios...
