Scoping fish-specific biocides

Project Leader: Graeme Allison, Vic Department of Primary Industries

Aim: To review fish specific biocides and their delivery mechanisms to assess potential biocides for use in Australia.

Project:  4.f.9

Project summary

Piscicides represent a potentially highly effective control option for aquatic species and are a standard fisheries management tool in North America. They are an essential component of any integrated pest management system, and would be a primary tool in any rapid incursion responses against new invasive fish populations. They are also an effective tool in the restoration of small to medium sized waterbodies.

Research and development of new piscicides has been limited and most countries still rely upon the non specific fish poisons, rotenone and antimycin.

This project undertook literature reviews, summarising the legislative and regulatory framework for the registration of chemicals as piscicides for use in Australia and New Zealand, identifying the scientific data and administrative processes required to enable the registration of known non-specific piscicides (rotenone and antimycin) in Australian and New Zealand freshwater environments, summarising the range of candidate compounds that are known to be lethal to selected invasive fish of concern in Australia and New Zealand, eg. carp and tilapia.

Key achievements

  • A report that summarises the regulatory framework for use of rotenone and antimycin in Australia.
  • Information on a range of candidate compounds known to be lethal to selected invasive fish of concern in Australia and New Zealand.
