Senator Brown asked the Minister for the Environment and Heritage, upon notice, on 30 August 2004:

With reference to alien invasive fish species in the Tasmanian Wilderness World Heritage Area:

(1) Have any alien invasive fish species such as trout and atlantic salmon been found in the Gordon or Franklin rivers in the Tasmanian Wilderness World Heritage Area; if so: (a) how many been found; (b) how far up the river systems have they been discovered; (c) what monitoring is taking place to identify: (i) the rate of their reproduction; and (ii) the rate of expansion of their range in these rivers; and (d) what impacts are these alien invasive fish species having on endemic species in Tasmanian rivers and lakes in the World Heritage Area.

(2) Have trout, atlantic salmon or any other alien fish invasive species been introduced in the past four years into any other rivers or hydro dams leading into river systems which rise in the World Heritage Area; if so, where.

(3) What environmental impact assessment was conducted before alien invasive fish species were permitted to be released or farmed in proximity to the World Heritage Area.

(4) Who gave permission for the releases.

Senator Ian Campbell (Minister for the Environment and Heritage) —The answer to the honourable senator's question is as follows:

The day-to-day management of the Tasmanian Wilderness World Heritage Area is the responsibility of the Tasmanian Government.

Fisheries management within the World Heritage Area, including the management of introduced fish species, is the responsibility of the Inland Fisheries Service. As such, the Inland Fisheries Service would be best placed to answer these questions.
