Objectives

1. Identify the main clupeoid species accessible in South-East Queensland and experimentally determine the seasonal abundance of these species.
2. Define size and age structure and examine the reproductive cycle of the major small pelagic species present in South-East Queensland.
3. Estimate egg densities and spawning biomass indices of the small pelagic clupeoid species present in South-East Queensland waters.
4. Examine methods of estimating potential fishery yields for a limited purse seine fishery in South-East Queensland.
5. Examine the species composition from experimental purse seining in South-East Queensland and comment on areas of possible conflict with other users.
6. Examine the potential impact of developing and existing purse seine fisheries on predator species.
