Need

It is accepted that the plight of our fresh water systems necessitates urgent action. FRDC itself identified the need for this project.

It is indeed significant that the comments provided in “Australia : State of the Environment” on each of the ten key threats to sustainability confirm that indicators of all ten show continuing deterioration.

While most of this broad spectrum of issues has been the subject of at least some research our knowledge of the interrelationships betwen fisheries and fresh water ecosystems remains seriously inadequate. Urgent requirements include:

· a current review of the factors which influence productivity of Australia’s inland fisheries,
· correlation of cause and effect for the major threats identified,
· correlation of cause with the relevant management or regulatory authority,
· an assessment of data and knowledge (research) needed to facilitate management action,
· an assessment of areas where research is most likely to lead to significant management action,
. an evaluation of what strategies have worked, or are working, in one or more State or
Territory and assessment of the likelihood of success from nationalising, or at least broadening
or transposing, this strategy,
. an assessment of potential cooperative approaches to commissioning and funding priority
research

Objectives

1. To identify the key issues facing the sustainability of Australia's freshwater fisheries resources and suggest strategies for addressing those of highest priority. Component objectives include:
2. To identify the major threats to sustainability of freshwater fisheries resources in each State and Territory.
3. To identify the probable primary causes for the most significant threats in each State and Territory.
4. To assess which threats could be approached by a national or State to State cooperative strategy for research.
5. To propose a national strategy for coordinating and funding new research relevant to ensuring the sustainability of Australia's freshwater fisheries resources

Summary

The plight of our freshwater systems necessitates urgent action. It is significant that the comments provided in 'Australia: State of the Environment' (SoEAC 1996) confirm that commonly used indicators of each of the ten key threats to sustainability show continuing deterioration. While most of the threats to freshwater systems have been the subject of at least some research/ knowledge of the interrelationships between fisheries and freshwater ecosystems remains seriously inadequate. Urgent requirements at the commencement of this project included:
• a current review of the factors which influence the productivity of Australia's
inland fisheries;
• correlation of cause and effect for the major threats identified;
• correlation of cause with the relevant management or regulatory authority;
• an assessment of data and knowledge needed to facilitate management action;
• an assessment of areas where research is most likely to lead to significant
management action;
• an evaluation of strategies that have worked, or are working/ in one or more
State or Territory and assessment of the likelihood of success from broadening
or transporting these strategies; and
• an assessment of potential cooperative approaches to commissioning and
supporting priority research
 
The present study identifies the six major threats to Australia's freshwater fisheries resources as:
• habitat degradation;
• pollution/water quality/water temperature;
• reduced environmental flows;
• barriers to migration;
• introduced species/carp; and
• fishing.
 
Each of these threats is examined in more detail in the report to provide answers to the requirements listed above.
