In collaboration with the New South Wales Department of Primary Industries we compared the effectiveness of the spanner crab monitoring systems used by New South Wales and Queensland and developed a fishery-independent survey protocol acceptable to both states.
The objectives of this project were to:
1. Determine the age at which spanner crabs (Ranina ranina) recruit to the fishery
2. Develop a common methodology for monitoring and assessing the Australian spanner crab stock
3. Investigate sources of variability in apparent population density
