Abstract:
Epibenthic community structure in Port Phillip Bay was examined from quantitative diver samples collected at 30 depth-stratified stations during 1998. Analysis of variance showed a strong trend of decreasing epibenthic abundance, biomass and species diversity with depth. Reductions in these three parameters were most pronounced over shallow inshore waters and could be attributed largely to decreases in the abundance of the heavy, mat-forming ascidian Pyura stolonifera with depth. Four epifaunal community groupings, closely reflecting differences in sediment and habitat type within the bay, were identified from ordinations of species abundance and biomass data. The four epifaunal groupings also closely matched distributional patterns observed in other studies in both demersal fish and infaunal communities. Epifaunal communities in the bay were dominated by filter-feeding organisms which accounted for nearly 95% of the total species abundance and 98% of the total species biomass. Seven of the 63 epibenthic organisms collected during the survey are exotic introductions to the bay (Sabella spallanzanii, Ascidiella aspersa, Styela clava, Styela plicata, Ciona intestinalis, Pyromaia tuberculata and Asterias amurensis). As many of these species are widespread and abundant (35% of all individuals), their effects on the ecology of Port Phillip Bay are likely to be significant.

Abstract:
James Fleming, a convict gardener, was a member of the party in the Colonial Schooner Cumberland, on a journey of exploration to Bass Strait and Port Phillip Bay in 1802 and 1803; they were the first Europeans to visit the northern part of the Bay and discovered the River Yarra. The acting Surveyor General of N.S.W., Charles Grimes mapped the whole Bay. Fleming wrote a journal of the expedition and the descriptions of the country on Grimes's map. Later in 1803, he compiled a list of plants introduced into the colony of New South Wales and returned to England on H.M.S.

Abstract:
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.

Abstract:
This study is dedicated to the hydrodynamic climate of Port Phillip Bay (PPB)—a largest coastal lagoon system in Victoria, Australia. Novelty of the present study includes long-term hydrodynamic hindcast simulations integrated with a spectral wave model. Specifically, a coupled unstructured grid wave–current modelling system (SCHISM + WWM) was built upon a high resolution and advanced wave physics (ST6). This coupling system was thoroughly calibrated and validated against field observations prior to applying for 27-year hindcast and case scenarios. Data from these simulations were then used to investigate the hydrodynamic climate of PPB focusing on three main aspects: water levels, waves and currents. For sea levels, this study shows that tidal and extreme sea levels (storm tides) across a large part of PPB have a similar magnitude. The highest storm tide level is found along eastern coasts of the bay in line with the wind pattern. In the vicinity of the entrance, the extreme sea level slightly reduced, in line with wave decay due to coupling effects. This extreme level is lower than results reported by previous studies, which were not built on a wave–current coupled system. For the wave field, the mean wave direction inside PPB is strongly affected by seasonality, in line with wind patterns. The 100-year return significant wave height is above 2 m along the eastern coasts. At PPH, waves get refracted after passing the narrow entrance. For currents, this study shows that both mean variations and high percentile currents are not affected by seasonality. This highlights the fact that tidal currents dominate flow movements in PPB. However, in extreme conditions, the circulation in PPB is also driven by wind patterns, forming two gyre systems. Based on case scenarios simulations, the strongest magnitude of wind-driven currents is above 0.5 m/s and found in the confined shallow region in the southern portion of PPB.

Abstract:
Plankton samples were collected on monthly cruises over 1 year from May 1983 to April 1984, to investigate composition, seasonality and distribution of ichthyoplankton in Port Phillip Bay. Fish egg numbers were dominated by the southern anchovy, Engraulis australis; clupeoids and gobiids were co-dominant larvae. Other common fish larvae were the cobbler, Gymnapistes marmoratus, greenback flounder, Rhombosolea tapirina, and callionymids. Egg abundances were highest in summer, resulting mainly from high abundances of E. australis eggs. Abundances of fish larvae were highest in summer and winter-spring. The summer period was dominated by clupeoid and gobiid larvae, together with callionymids, monacanthids, platycephalids, the blenny, Pictiblennius tasmanianus, the snapper, Chrysophrys auratus, and a number of rarer species. The winter-spring period was almost entirely dominated by four taxa: gobiids, G. marmoratus, R. taplrina and the long-snouted flounder, Ammotretis rostratus. Eggs of E. australis, Sardinops neopilchardus and A. rostratus, and larvae of all common taxa except monacanthids and C. auratus, were distributed widely throughout the bay. Abundance of eggs of E. australis at the mouth of the bay was significantly lower than within the bay proper. Larvae of P. tasrnanianus were significantly more abundant in the shallow, northern region of the bay than in the deeper, central region. Most monacanthid larvae were collected towards the mouth of the bay, whereas C. auratus larvae were only collected at stations well inside the bay. Analysis of winter samples revealed multispecies patchiness of fish larvae, and a positive correlation between larval abundance and volume of net zooplankton. Although juveniles of King George whiting, Sillaginodes punctatus, and yellow-eyed mullet, Aldrichetra forsteri, are abundant in Port Phillip Bay, larvae were virtually absent. It is proposed that these species spawn offshore, and that immigration into the bay occurs at a late larval-early juvenile stage not detectable by plankton sampling.

Full text
Abstract:
Five species of Scyphomedusae were identified from plankton samples collected betwen April 1983 and June 1985 in Port Phillip Bay: Cyanea capillata, Pseudorhiza haeckeli, Aurelia aurita, Pelagia noctiluca and Catostylus mosaicus. Abundances of Scyphomedusae fluctuated seasonally. Cyanea capillata was dominant between May and September with maximum abundances of approximately 100 adults per 1000 m3 (mean 3.5 per 1000 m3) and 200 ephyrae per 1000 m3 (mean 16.5 per 1000 m3). Ephyrae of C. capillata were present throughout the year with a maximum biomass between May and July. Pseudorhiza haeckeli was dominant between November and April with maximum abundances of approximately 100 adults per 1000 m3 (mean 1.8 per 1000 m3). Aurelia aurita was collected throughout the year, P. noctilraca occurred from January to April, and C. mosaicus occurred from September to March.

Full text
Abstract:
Information from this thesis provides a critical understanding of the environmental factors that influence the growth and reproduction of different life stages of Undaria pinnatifida in Port Phillip Bay. Such information is important towards understanding the potential spread of this invasive species and may provide insight into methods that can be used to limit its expansion in southern Australian waters. In 1996 Undaria pinnatifida (Harvey) Suringar (Laminariales: Phaeophyta) was found growing in coastal waters of Port Phillip Bay, Victoria, Australia. Undaria pinnatifida is an opportunistic colonizer capable of high rates of reproduction and fast growth rates producing high density populations. It is the dominant macroalgal species at the site of invasion during winter and spring and has the potential for further spread from its current distribution in the northern part of Port Phillip Bay. This is the first in Australia examining the effects of temperature, nitrogen concentration, photon flux density and photoperiod on germination of zoospores, gametophyte growth and reproduction of U. pinnatifida in culture. Information on its recruitment, growth and reproductive capacity in the field is also presented for the first time for a population Australia.

Full text
Abstract:
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.
