Chemical investigation of a Dictyodendrilla sp. from Port Phillip Bay, Victoria, yielded three new oxygenated sesquiterpenes, dictyodendrillin -A (6), -B (7) and -C (8), together with the known sesquiterpene dendrolasin (9). Structures for all these metabolites were established by spectroscopic analysis.

A specimen of a marine sponge, Spongosorites sp., collected in Port Phillip Bay, Victoria, Australia, has yielded the alkaloid (2). The structure of (2) was secured by spectroscopic analysis, chemical derivatization and synthesis of a dihydro derivative (4). The antibiotic property of the crude ethanol extract of this sponge was attributed to (2).

The degree of haemosiderin deposition in the spleen, liver, and kidney of P. bassensis and D. nicthemerus was compared in specimens from Port Phillip Bay, and Lakes Entrance, Victoria, Bass Strait, and the Derwent estuary, Tasmania. D. nicthemerus displayed extensive visceral haemosiderosis and fatty infiltration of the liver at all sites, apparently as normal conditions. P. bassensis from Port Phillip Bay displayed severe visceral haemosiderosis, whereas specimens from the remaining sites had only low background levels of haemosiderin deposition. It is suggested that high levels of visceral haemosiderin in fish species normally displaying low levels are indicative of a suboptimal health status in fish populations. No infectious cause of the haemosiderosis in Port Phillip Bay fish has been identified, and toxic or pollution-related causes are thus considered likely to be responsible.

A Latrunculia sp. collected off Port Phillip Bay, Victoria, returned three new norsesterterpene cyclic peroxides. Trunculins G (9), H (10) and I (11) were isolated as their methyl esters (12), (13) and (14) respectively. Gross structures for these new trunculins were assigned on the basis of spectroscopic analysis, while the absolute stereochemistry about the cyclic peroxide terminus was established by application of the Horeau and Mosher procedures.

Length–frequency and maturity data of pilchards (Sardinops sagax) are described from monthly purse-seine commercial catch samples obtained in Port Phillip Bay (Victoria) between December 1994 and January 1997. These data, together with findings of a 12-month ichthyoplankton bay survey from September 1995 to August 1996, were used to determine the size at which pilchards recruit to the bay fishery and whether they spawn within this system. Monthly pilchard catch rates between January 1990 and June 1996 are also described and analysed in terms of environmental variables during that period. Results show that pilchards do not generally attain sexual maturity or spawn within the bay but use it as a nursery area, entering this system mostly as 0+ to 1+ year-o ld juveniles (4–12 cm fork length, FL) in late spring–early summer and returning to sea the following winter. This migration is supported by the marked seasonality in catch rates, which each year peak in March–May and are lowest in August–October. The seasonality was adequately explained by temperature lagged 2 months in a multivariate time-series model. Port Phillip Bay appears to be the only semi-enclosed, shallow marine embayment in temperate Australia that supports a substantial pilchard fishery that, in addition, is based predominantly on juveniles.

This investigation was designed to provide preliminary information to the Environment Protection Authority concerning the input of faecal matter to stormwater drains in the Rippleside area of Geelong, Victoria. Results derived from the combined use of sterol biomarkers (e.g. coprostanol and 24-ethylcoprostanol) and four sub-groups of bacterial indicators (e.g. thermotolerant coliforms, E. coli, faecal streptococci and enterococci) indicated that during wet weather, all sites sampled were affected by significant human faecal contamination. Ratios of coprostanol to bacterial indicators were similar to those for samples collected from nearby sewer mains. During dry weather, there were still severely elevated levels of faecal contamination based on bacterial indicators, but correspondingly low concentrations of faecal sterols suggesting minimal human or herbivore faecal contamination. The origin of the majority of the faecal pollution in dry weather therefore remains to be fully explained. It is clear from this and related studies that the combined measurement of faecal sterols and bacterial indicators can greatly assist distinguishing sources of faecal pollution. It is also shown for aquatic environments that the measurement of coprostanol or other single indicators alone, is inadequate to fully discern faecal contamination from human sources.

Marine macroalgae occurring in the south eastern region of Victoria, Australia, consisting of Port Phillip Bay and the heads entering the bay, is the focus of this review. This area is home to approximately 200 different species of macroalgae, representing the three major phyla of the green algae (Chlorophyta), brown algae (Ochrophyta) and the red algae (Rhodophyta), respectively. Over almost 50 years, the species of macroalgae associated and occurring within this area have resulted in the identification of a number of different types of secondary metabolites including terpenoids, sterols/steroids, phenolic acids, phenols, lipids/polyenes, pheromones, xanthophylls and phloroglucinols. Many of these compounds have subsequently displayed a variety of bioactivities. A systematic description of the compound classes and their associated bioactivities from marine macroalgae found within this region is presented.

Increasing exploitation of pelagic fish populations worldwide has often resulted in overfishing and the collapse of commercial fisheries and associated serious declines in many marine predator populations, including seabirds. These events highlight the competing demands for limited marine resources. Recent emphasis for the ecologically sustainable management of commercial fisheries has stimulated attempts to manage fisheries by incorporating knowledge of trophic interactions and ecosystem functioning, known as ecosystem-based fisheries management. Seabirds are often highly visible, wide-ranging upper trophic level consumers that aggregate in areas of increased ocean productivity and therefore be used as natural monitors of marine environmental conditions. Further, many seabirds commonly fed on commercially-exploited fish stocks (often targeting prey of similar size). In this study, the population dynamics of Australasian gannets (Morus serrator) breeding in Port Phillip Bay, Victoria, is investigated and competition between gannets and commercial fisheries is determined. In addition, the potential use of seabird reproductive and population parameters as indicators of the abundance of commercially exploited fish stocks, and pelagic conditions generally, is assessed.

This study investigated the effects of nitrogen and phosphorus on the growth and ecophysiology of a number of dominant species of macroalgae at a site in Port Phillip Bay (PPB), a large shallow water marine embayment located on the central southern coast of Victoria, Australia. This thesis investigated the physiological processes (i.e. photosynthesis, growth, nutrient uptake) of three species of macroalgae, Hincksia sordida (Harvey) Clayton (Phaeophyta), Polysiphonia decipiens Montague (Rhodophyta) and Ulva sp. (Chlorophyta) in response to a range of environmental regimes.
