Habitat and fisheries production in the South East Fishery ecosystem

In 1994 CSIRO and FRDC started a 5-year ecosystem study of the southeastern Australian continental shelf. Fisheries management in this area is currently based on individual species. Our goal was to identify ecosystem features that could extend the data available to manage the fisheries in this...

Effects of seasonal and interannual variability of the ocean environment on recruitment to the fisheries of Western Australia

The relatively high catch of invertebrate species in Western Australia compared to finfish is in sharp contrast to other regions of the world where finfish production usually dominates. This low level of finfish production is primarily due to the Leeuwin Current which brings warm, low nutrient...

Development of software for use in multi-frequency acoustic biomass assessments and ecological studies

The development of the ECHO software has enabled the collection and analysis of large multifrequency acoustic data sets. The data can now be processed in a timely manner (via overlays) to quality assure and interpret underlying acoustic characteristics in the signals. From these analyses we can...

Development of biological tagging techniques for penaeid prawns

The objective of this project was to develop novel biological tags for penaeid prawns. The impetus for this research was the growing interest in Australia in the potential for stock-enhancement of penaeid fisheries with hatchery reared juveniles. In any stock- enhancement program some...

Quantitative interpretation of fine-scale SBT catch per unit effort for south east Australia

An analysis of spatial and temporal variations in catch rates of Southern Bluefin Tuna (SBT) in relation to environmental factors was conducted for the region south of Tasmania up to 1he southern half of New South Wales. Substantial temporal and spatial variations were evident in...
