1. To produce an age-structured, spatial-temporal fishery model for King George whiting in South Australia based on a comprehensive understanding of its biology, life-history and genetics as well as an analysis of the fishery. This model will be used as a stock assessment tool to assess management options.
2. To implement a biological research programme to facilitate objective 1/, including: a/. determination of site-specific age-structures based on ageing fish using otoliths, to be used for estimation of demographic parameters
b/. completion of the understanding of the life-history including reproductive, early and adult biological information
c/. assessment of genetic variation amongst populations over two spatial scales (amongst states and amongst regions within SA).
3. To review current commercial catch and effort information to: a/. identify the value of such data for estimating population abundance
b/. continue an on-going assessment of impacts of technological advances in fishing equipment on catch and effort in the commercial sector of the fishery
c/. compare commercial catch with that from recreational catch information currently being collected in SA using creel surveys (FRDC 92/81).

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 and interrogate results of the simulation via in-built statistical, curve fitting and indicator analysis modules.
