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...

Assessment of juvenile eel resources in south-east Australia

Project number: 1994-067
Project Status:
Completed
Budget expenditure: $279,545.00
Principal Investigator: Geoff Gooley
Organisation: Agriculture Victoria
Project start/end date: 17 Sep 1994 - 26 Mar 2000

FRDC

Objectives

1. To characterise and qualitatively assess A. australis glass eel migration into coastal catchments of southern NSW, Victoria and Tasmania for the purpose of investigating potential for commercial exploitation of glass eels on an ecologically sustainable basis.
2. To adapt intensive/semi-intensive, pond/tank culture technology for the purpose of enhancing survival and viability of translocated juvenile eels, including glass eels, to be used in restocking/extensive production and/or intensive production to market size.

Summary

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

Need

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.

Objectives

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.
