1) There is need to incorporate environmental data in understanding larval dispersal and stock-recruitment relationships for two major crustacean fisheries, prawns and blue crabs, in SG.
2) There is a need to identify regions critical for spawning and settlement success for prawns and blue crabs.
3) There is a need to develop optimal harvesting strategies for prawns during the pre-Christmas fishing period, to maximise catch and minimise the impact on future recruitment to the fishery.
4) There is a need to understand the effect natural variations in physical environmental parameters (including winds and tides) have on larval ecology and recruitment success for prawns and blue crabs in SG.
5) There is a need to develop tools to inform on the threat for major fishery resources from climate change by understanding impacts of temperature change on stock-recruitment relationships for these fisheries.

SPECIES
1. Develop biological models for the reproductive and larval biology of prawns and blue crabs.
2. Develop a passive particle hydrodynamic model of Spencer Gulf.
3. Develop the base case physical/biological model for prawns and blue crabs. Conduct sensitivity studies for different scenarios of environmental conditions (e.g. water temperature, wind strength).
4. Determine scenarios to optimise the harvest of western king prawns during the early spawning season.
