Assessment of juvenile eel resources in south-east Australia
Final report
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?

Development and evaluation of methods to assess the impact of chronic toxicity on ichthyoplankton: a pilot study
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.
