The sabellid polychaete Sabella spallanzanii, a native to the Mediterannean, established in Port Phillip Bay in the late 1980s. Initially it was found only in Corio Bay, but during the past five years it has spread so that it now occurs throughout the western half of Port Phillip Bay. Densities in many parts of the bay remain low but densities are usually higher (up to 13/m²) in deeper water and the worm's distribution extends into shallower depths in calmer regions. Larvae probably require a 'hard' surface (shell fragment, rock, seaweed, mollusc or sea squirt) for initial attachment, but subsequently they may use their own tube as an anchor. The only measurable effect of the spread of S. spallanzanii on fish communities was an increase in the abundance of little rock whiting, which uses the habitat created by the forest of S. spallanzanii tubes. No fish has been found to prey on S. spallanzanii, possibly because their feeding crowns contain particularly high levels of vanadium.

 The channelling of particulate food away from native filter-feeders may have considerable long term effects on fish communities. As the density and coverage of S. spallanzanii increases more energy may be channelled into trophic pathways that appear to lead only to bacterial breakdown upon the death of the worms. S. spallanzanii may also significantly affect the growth and survival of other epifauna with which they compete for food and suitable settlement surfaces.

Twenty two exotic species of marine invertebrates have been recorded from Victorian waters. Eighteen of these are reported from Port Phillip Bay and four are known only from other localities in Victoria. Some of the exotic species recorded from Port Phillip Bay are well established and are present in large numbers, some have been recorded only as isolated individuals and the occurrence of others has been reported but not confirmed.

In this report, literature on the exotic species recorded from Victoria is reviewed, with particular attention being given to those species recorded from Port Phillip Bay. Potential impacts of these introduced species on the local marine fauna are discussed.

S. spallanzanii may also significantly affect the growth and survival of other epifauna with which they compete for food and suitable settlement surfaces.

Twenty two exotic species of marine invertebrates have been recorded from Victorian waters. Eighteen of these are reported from Port Phillip Bay and four are known only from other localities in Victoria. Some of the exotic species recorded from Port Phillip Bay are well established and are present in large numbers, some have been recorded only as isolated individuals and the occurrence of others has been reported but not confirmed.

In this report, literature on the exotic species recorded from Victoria is reviewed, with particular attention being given to those species recorded from Port Phillip Bay. Potential impacts of these introduced species on the local marine fauna are discussed.

The sabellid polychaete Sabella spallanzanii, a native to the Mediterannean, established in Port Phillip Bay in the late 1980s. Initially it was found only in Corio Bay, but during the past five years it has spread so that it now occurs throughout the western half of Port Phillip Bay. Densities in many parts of the bay remain low but densities are usually higher (up to 13/m²) in deeper water and the worm's distribution extends into shallower depths in calmer regions. Larvae probably require a 'hard' surface (shell fragment, rock, seaweed, mollusc or sea squirt) for initial attachment, but subsequently they may use their own tube as an anchor. The only measurable effect of the spread of S. spallanzanii on fish communities was an increase in the abundance of little rock whiting, which uses the habitat created by the forest of S. spallanzanii tubes. No fish has been found to prey on S. spallanzanii, possibly because their feeding crowns contain particularly high levels of vanadium.

 The channelling of particulate food away from native filter-feeders may have considerable long term effects on fish communities. As the density and coverage of S. spallanzanii increases more energy may be channelled into trophic pathways that appear to lead only to bacterial breakdown upon the death of the worms. S. spallanzanii may also significantly affect the growth and survival of other epifauna with which they compete for food and suitable settlement surfaces.

In the face of declining world production of freshwater, anguillid eels, together with largely unsatisfied export market demand for such eels and eel produce, a commercial premium is being placed on the development of intensive eel culture technology and the associated utilisation of glass eel seedstock. For the purposes of this study it is assumed that any significant increase in Australian shortfin eel production over current levels will primarily occur with the adoption of intensive aquaculture practices based on the sustainable use of wild glass eel seedstock. Based on this rationale, the need for the present study is succinctly summarised as:

1. Glass eel assessment

• Do we have an accessible shortfin glass eel resource in Australia, and, if so,
• Where, when and how can we efficiently and effectively harvest glass eels sustainably?

2. Glass eel culture

• Can we commercially culture shortfin glass eels in Australia, and if so,
• Where, when and how can this best be done in an economically viable way?
