Demonstration site: Albert-Logan, Queensland

Project Leaders: Andrew Norris and Michael Hutchison, DEEDI

Aim: To look at community involvement in carp management and control and in particular to look at the value of recreational fishing competitions as a control option.

Projects:  10.f.8 

Project summary

The objectives of this demonstration site are to investigate the impact and effectiveness of community involvement in the effective management of invasive species, and to demonstrate the feasibility of eradicating or managing an established invasive fish species in a catchment system using new and current technologies.

The Albert and Logan Rivers are located in South-east Queensland between Brisbane and the Gold Coast.

The main outcomes of this demonstration site are:

  • Reduced levels of carp in the Logan and Albert Rivers Catchment
  • Increased capacity to effectively control carp in a range of habitats using a variety of technologies
  • Knowledge of the effectiveness of new and novel IA CRC carp control technologies and strategies in the field
  • Increased effectiveness of community based pest fish control efforts
  • More effective invasive species control through a better understanding of the drivers behind community participation and a series of Best Practice Guidelines
  • Greater community understanding and willingness to participate in invasive fish control.

This project examined pest fish control options at the catchment scale. Control measures involved both low tech and high tech solutions and strong community participation. Each of these were comprehensively tested and evaluated under field conditions, leading to an analysis of cost-effectiveness that highlights methods most appropriate to different habitats and circumstances. Methods proven to be successful are now available for take-up in other catchments in Australia and elsewhere.

Associated PhD student Katie Doyle has continued her investigation on the impact of increased predator presence on carp populations, completing tank trials with Australian bass and Murray cod.

Key achievements

  • Research into the impacts of carp fishing competitions on local carp populations has been completed and reported on.
  • Surveys of three carp fishing events resulted in minimal carp population reductions (<1.8%), especially when compared with electrofishing (resulting in carp population reductions up to 16.1 per cent). The catch per unit effort was nearly 100 times greater for electrofishing than for angling.
  • Although carp population impacts are negligible from competitions, the report highlights the non-tangible benefits of competitions, and discusses how competitions can be incorporated into an integrated management strategy.
  • A second report has been completed that provides instructions, in the form of a handbook, for running carp competitions.
  • Research assessing the effectiveness of individual techniques was completed at nine sites (3 upland sites, 3 main river sections and 3 off-stream water bodies). At each site a range of techniques was applied concurrently, and where possible in an integrated manner for a period of one week. The effectiveness assessment included a comparison of catch rates, non-target by-catch, size selectivity, cost, and catch per unit effort. Reporting on this research is nearing completion.

Key deliverables

  • Published paper on the human dimensions of carp competitions.
  • Published paper on the cost-effectiveness of single or integrated control techniques.
  • Final report published by the end of 2009.
