The objectives of this project were to develop length-based approaches for estimation of natural, fishing and total mortality, and to explore the application of these methods to the data from selected fisheries. The methods that were developed were essentially length-based versions of age-based...
It is now widely recognized that fisheries can have impacts on marine species, habitats and ecosystems beyond the direct impacts of fishing on target species. For example, hundreds of species are regularly caught and discarded in many trawl and longline fisheries and in particular, interactions with...
This study investigated the distribution of the expression of selected members of the peroxiredoxin (Prx) and glutathione peroxidase (GPx) antioxidant enzyme families in YTK (Seriola lalandi), an important finfish aquaculture species in South Australia.
The purpose of investigating the expression of...
Rock lobsters can be exposed to poor water quality during all stages of handling and holding prior to going to market. Poor water quality reduces the time a lobster can be held alive and how many animals can be held in a system and thus may reduce profit. The quality of water can be assessed using...
By world standards Australia has not developed a significant marine finfish fanning industry. One of the principal constraints has been the absence of suitable technology for Australian species. This technology is currently being developed in a number of research facilities in temperate regions of...

The objectives of this study were to determine whether catch rates of rock lobsters in the commercial fishery off New South Wales were declining, the size and species composition of catches from the commercial fishery and to ascertain the smallest length at which 50% of female eastern rock lobsters,...
