Most fisheries in Australia are at sustainable levels or are overexploited. There is obviously a need to maximise yields from these resources. Consequently it is vital for fishery management to be able to discriminate between the effects of harvesting the resource versus the impacts of anthropogenic inputs on populations.
Funds are sought from FRDC to conduct a pilot program for developing methods of determining the impacts of chronic toxicity on fish eggs and larvae. This approach allows the measurement of the entire pollution load of an ecosystem. The successful application of this technique will allow fisheries managers to quantify the total toxicant loadings in habitats and to evaluate the potential impacts these toxicant loads have on fishery stocks.
The results of this Pilot study will have general applicability to temperate and subtropical systems. The usefulness of similar techniques to monitor ecosystem health has been demonstrated for tropical systems by Klumpp and von Westernhagen.
1. Development methods for using imaging analysis as a tool for rapid and objective identification of fish eggs, teratogenic abnormalities and chromosome aberrations.
2. Evaluate the applicability of the "fish egg abnormality technique" for temperate species and evaluate its use in Port Phillip Bay.

Development of a harvest management, governance and resource sharing framework for a complex multi-sector, multi-jurisdiction fishery: the south-east Australian ‘western’ snapper stock
This report involves the ‘Western Victorian Snapper (Chrysophrys auratus) Stock’ (WVSS) which supports arguably the most important marine fin-fish fishery for Victoria. While the majority of the harvest is by Victorian fisheries, this stock is a straddling stock shared with South...

Evaluation of methods to assess abalone abundance
The issue of how best to survey abalone populations to obtain estimates of abundance has been the subject of debate among fisheries biologists for many years. In an attempt to resolve this issue we compared and evaluated abalone abundance estimated by the following methods: Transect survey,...

Environmental determinants of recruitment success of King George whiting
Catches of King George whiting in Victorian bays and inlets vary greatly from year to year. This research was aimed at finding out how much of this variation was due to the environment, and whether we could use measures of environmental variables to predict catches in the future. King George whiting...

Development of methods to age commercially important dories and oreos
Four species of dories (Family: Zeidae) and five species of oreos (Family: Oreosomatidae) are caught in the South East Fishery (SEF). John dory and mirror dory are included in the SEF quota sytem with Total Allowable Catches (TACs), in 1993, of 240 t and 800 t, respectively. Oreos, originally a...

Development of a guideline to investigate and understand disease outbreaks of unknown cause
This handbook presents guidelines that have been developed to use in the event of a disease outbreak in aquatic animals including finfish, molluscs and crustaceans. For the purposes of these guidelines, in the context of an outbreak, the term “disease” will be used for any event where...
