Allans idea of allready closed river is a good idea to get these fish going,and your idea of stocking them also good but the costs at first the federal government should pay to set up a breeding program for Maccas as they are difficult to breed need a totally different system to what they have now,with the first of the fingerlings going into a few allready closed rivers.After this then they could use RFL funds to stock rivers impoundments with Maccas great idea.
Go natives.
Dave, its unlikely that the Commonwealth government will give the Carr government money to oversee an essentially state based management/obligational matter under the existing NSW Fisheries Department.
The legalities of offering money would dictate caveat be required on how the funds are spent, and the Carr government wouldnt sign off on that in a million years.
Some good points Jim. But we will have to agree to disagree on some aspects.
I think Trout have been the primary cause of MacPerch decline in rivers that have not suffered serious siltation, regulation by dams or exotic Redfin populations.
Such examples include the often mentioned Goodradigbee River.
I think it is realistic to expcet that an introduced aquatic predator is going to have the same devestating effects on native aquatic fauna that introduced terrestrial predators (eg cats, foxes) have had on native terrestrial fauna.
I also think it is a concern that Rainbow Trout - supplied courtesy of NSW Fisheries - continue to be stocked in the remnant Macquarie Perch habitat Jim mentions, and that Rainbow Trout have been shown to be significant carriers of EHN virus.

Again Shane you prove your inability to reasonable on the issue.
Even if all of the 6 or so waterways I advocated for Trout removal and return to upland natives WAS returned to upland natives, Trout would still be left in the privileged position, dominating the vast, vast majority of upland habitats in SE Australia.
Isn't this good enough for you.
Try viewing this issue beyond the narrow "I like to fly-fish for Trout" perspective.

You disagree with every thing that is put up here evan though you have no proof,and you say that Maccas cant live with Trout yet to many have said they do and they do breed with Trout.But I suspose that cant be true can it.
Trying putting your surname to your posts for a start.

There's plenty of proof.
And yes, small numbers of Macquarie Perch manage to live and breed alongside Trout in a handful of upland rivers/streams. But is it sustainable??? (considering the predation and competition by the Trout on juvenile Macquaries). Going by the majority of upland rivers that Macquarie Perch have become extinct in, and that they are becoming extinct in the last few upland rivers they occur in, the answer is a resounding "NO".
I would think that resetablishing Maccas and TCs would fall under the brief for the MDB fund so I think this is a source where federal funding could be obtained.
