Objectives

1. To determine the origins of Snapper that occupy the different regions of South Australian waters, and determine if and when during their life histories that any large-scale movement took place to account for current patterns of dispersion. This will be based on a suite of otolith-based techniques.

2. To develop a better understanding of the movement behaviour of Snapper at several spatial and temporal scales throughout Gulf St. Vincent (SA), using acoustic telemetry techniques.

3. To develop a better spatial management strategy for the Snapper fisheries of south eastern Australia based on our enhanced understanding of inter-regional and cross-jurisdictional fish movement.
