Marine cage farming of salmonid fish (salmon and trout) is well established in Tasmania.
There is an established regulatory framework, administered by the Department of
Primary Industries, Water and Environment (DPIWE), which controls licenses, leases and
environmental conditions on cage farms and associated land-based facilities. Similarly,
there is an established land-based freshwater hatchery industry primarily focussed on
producing juvenile/pre-smolt fish for the marine cage sector, but also involved in
producing some table fish. Again, there is a regulatory framework for this sector, with
licensing, EIA and EPMP requirements, administered by DPIWE and the Inland Fisheries
Commission (IFC), now the Inland Fisheries Service (IFS).
The aquaculture industry is seeking the establishment of cage salmonid culture facilities
at several locations in freshwater lakes. There is, at present, no specific policy or
regulatory framework in relation to this development. This report has been commissioned
by IFC to address several key issues including:

- identification and assessment of any environmental risks, including any disease
management issues, that are relevant to a decision to allow or disallow freshwater
lake cage culture in Tasmania;

- investigation of best practice in the cage farming sector;

- proposal of a best practice environmental management approach to lake cage farming,
with an emphasis on methods to reduce potential risks and impacts;

- documentation of overseas experiences with freshwater cage culture.
