The influence of fish movement on regional fishery production and stock structure for South Australia's Snapper (Chrysophrys auratus) fishery
SARDI Food Safety and Innovation
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.
