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.

Seafood CRC: controlling biofouling of pond aerators on marine prawn farms

Biofouling of aeration equipment is a significant farm management issue and production cost for Australian marine prawn farms. Defouling aeration equipment has a high labour demand and once fouled, the energy efficiency of paddle-wheels and other aerating equipment can be markedly reduced, leading...

Stock predictions and spatial population indicators for Australia's east coast saucer scallop fishery

This project undertook analyses to understand the role of overfishing and the environment on saucer scallops. The analyses indicated reduced numbers of spawning scallops. Historical levels of fishing and environmental influences such as from increased sea surface temperatures (SST) have amplified...

The effect of barramundi Nodavirus on important freshwater fishes

This project has confirmed the knowledge that management of barramundi translocations outside their natural range requires fisheries authorities take into account the risk that barramundi nodavirus may lethally infect native freshwater fishes. The project has shown barramundi nodavirus can...

Understanding environmental and fisheries factors causing fluctuations in mud crab and blue swimmer crab fisheries in northern Australia to inform harvest strategies

This project investigated relationships between environmental factors and harvests of crabs in the Gulf of Carpentaria (GoC), northern Australia. Desktop correlative analyses clearly indicated that recent fluctuations in the catches of Giant Mud Crabs in the GoC are most likely driven by...
