To effectively manage most fisheries, including penaeid prawn fisheries in northern and eastern Australia, it is important to know the relationship between the size of the spawning population and the number of young adults that recruit to a fishery in the next generation. In the tiger prawn fishery...
Several critically important steps to achieving the central long-term aim of this project namely, cost-effective enhancement of abalone fisheries using hatchery produced seed stock, were achieved. The first was year-round controlled temperature conditioning and spawning of captive broodstock. This...
The 2015-229 “Oysters Australia IPA - workshop - identifying knowledge gaps for development of the native oyster aquaculture industry in South Australia” brought together oyster farmers, hatchery operators and scientists from across Australia to share their knowledge and experience with native...
This project has been highly successful at determining factors that affect the outputs and outcomes of the model and the uncertainty underlying the model system. The report has been divided into seven broad sections and two Appendices. The first chapter contains the context of the work;...
This project studied environmental factors which may be influencing the recruitment, catchability or productivity of Snapper, Pearl Perch, and Spanner Crab stocks in Queensland. Two environmental variables: GSLA and Chl-a were found to have strong associations with either abundance or catchability...
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...
