Nutritional related aspects of the artificial propagation and larval rearing of Macquarie perch, Macquaria Australasica (Cuvier, 1830)

Studies the underlying role of nutrition in the lack of response of captive fish to hypophysation. Aspects studied include morphological characteristics, histology of ovaries, proximate analysis, fatty and amino acid profiles of oocytes, muscle, liver and diets of wild and tank-reared fish, egg and larval quality, amino acid composition of eggs and larvae at different developmental stages, larval feeding and hormone treatments.

Field evaluation of a suite of biomarkers in an Australian Tropical Reef Species, Stripey Seaperch (Lutjanus carponotatus) : Assessment of Produced Formation water from the Harriet A Platform

There is paucity of data regarding hydrocarbon exposure of tropical fish species inhabiting the waters near oil and gas platforms on the Northwest Shelf of Australia. A comprehensive field study assessed the exposure and potential effects associated with the produced water (PW) plume from the Harriet A production platform on the northwest shelf in a local reef species, Stripey seaperch (Lutjanus carponotatus). This field study was a continuation of an earlier pilot study which concluded that there were “warning signs” of potential biological effects on fish populations exposed to PW. A 10-day field caging study was conducted deploying 15 individual fish into 6 separate steel cages set 1-m subsurface at 3 stations in a concentration gradient moving away from the platform. A battery of biomarkers were evaluated including hepatosomatic index (HSI), total cytochrome P450, bile metabolites, CYP1A-, CYP2K- and CYP2M-like proteins, cholinesterase (ChE) activity, and histopathology of liver and gill tissues. Water column and PW effluent samples was also collected. Results confirmed that PAH metabolites in bile, CYP1A-, CYP2K-, and CYP2M-like proteins and liver histopathology provided evidence of significant exposure and effects after 10 days at the near-field site (~200 m off the Harriet A platform). Hepatosomatic index, total cytochrome P450, and ChE did not provide site-specific differences by day 10 of exposure to PW. CYP proteins were shown by principal component analysis (PCA) to be the best diagnostic tool for determining exposure and associated biological effects of PW on L. carponotatus. Using a suite of biomarkers has been widely advocated as a vital component in environmental risk assessments worldwide. This study demonstrates the usefulness of biomarkers for assessing the Harriet A PW discharge into Australian waters with broader applications for other PW discharges. This approach has merit as a valuable addition to environmental management strategies for protecting Australia’s tropical environment and its rich biodiversity.

Spirit-music unbound: Romanticism and print politics in Australian women's poetry 1830-1905

This thesis presents a re-mapping of Australian poetic tradition to reflect the presence of colonial women poets. The research recovers a wide range of neglected poetry, offering a new way of reading these important poets as politic and transnational, particularly through the significance of newspaper authorship and international women’s poetry.

Education and work in service of the nation: Canadian and Australian girls' fiction, 1908-1921

This chapter compares early twentieth-century Australian novels by Ethel Turner, Mary Grant Bruce, and Lilian Turner to Canadian novels by Nellie McClung and L.M. Montgomery to demonstrate important differences in attitudes towards education and work. Girls’ fiction in these white settler colonies has many similarities, containing strong ideals related to domesticity, education, employment, and femininity. In the Canadian fiction, attitudes towards women’s higher education and employement are generally much more positive. Although both Australian and Canadian girls’ fiction typically conclude with marriage, Montgomery’s Anne of Green Gables and Nellie McClung’s Pearlie Watson are offered the opportunity to pursue higher education and use this education to teach others. In contrast, Lilian Turner’s Paradise and the Perrys, Ethel Turner’s Fair Ines, and Mary Grant Bruce’s ’Possum emphasise the importance of domesticity while also showing how girls sought to earn income without leaving home. Through our comparison of these Canadian and Australian novels, all published between 1908 and 1921, we demonstrate how the different feminine ideals embodied through these heroines are inevitably intertwined with the needs of the nation
