Abstract

For a number of years silver perch, a species native to the Murray-Darling river system of eastern Australia, has been allowed into Western Australia for the purpose of stocking rural, inland farm dams. Improts have only been allowed under licence, subject to disease-free certification and on the basis of fish being placed into impounded waters. The development of commercial aquaculture of a non-endemic species such as silver perch raises a number of important issues relating to tanslocation. These include potential of the introduced species to: Impact on genetic diversity, Introduce disease, Impact on the natural environment and the biodiversity of native species. This Management Paper has been drafted in liaison with the Department of Environmental Protection in accordnace with the principles of risk assessment, taking into account the above issues. It is considered that the implementation of this policy will protect the natural environment and native fish species. It will also allow for the develpment of a silver perch industry and provide the first step towards self-regulation of that industry.
