Has anyone actually caught a MRC in North pine?

I know of at least one caught at Bullockys rest during the drought and have seen a couple that were electrofished below the dam by fisheries during lungy recoveries.
 Cheers
Ray

Yes 9 confirmed captures from the dam from a little 25cm tacker to 90cm + all released.
From  below the dam where they are No Take, 12 confirmed (2 possibly caught twice) 4 electrofished, 1 salvaged, 1 line caught all returned to the dam. 3 caught and released (one of these most likely one of the ones electrofished) 2 caught and taken one of these most likely one of the ones caught and released. One 62cm fish taken in the 09 Bass closed season by an angler who thought it was a murray, had no idea there was a closed season or Mary's  and was fishing there as a result of reports of the location on another forum.
Also have the complete stocking history of MRC for the entire Pine Rivers Catchment.

I feel that DNA testing should sort out the discussion.

The problem that I feel is more important is the protection of the fish in those river systems that Fitzy refered to.

I have been carring out 'Catch and Release' in the Stanley for aprox 5 years now and have seen a massive decline in the MR Cod to the stage where there may be none left.  It is years since the last report of one being caught by the local club.

Also reports keep coming to me of long lines being seen across the River. Bloody nice hey. 

If there is any possibility at all of Cod reproducing in these streams then they should be "closed off to all fishing" in the snaggy areas. Then get back to releasing fingerlings again.  These area would make great feeder nurseries for the dams below.

It would be so easy to test if some of the hatchery Cod might like a feed of Tilapia finglings. This could be a food source and a reason for large Cod to enter the dams. 

For every Bass landed in Somerset there 10 to 15 Tilapa with half a dozen Eail Tails as well.  That is what the future holds unless some effort is made to change things.

Leave it with you fellas. Shoot my ideas up if you must but dont miss the big picture.

Regards BG

Thanks, the stocking history would make interesting reading

One that has limited broodstock and not much success collecting any thus far due to the amount of rain we have had.
No idea what is happening at Gerry Cook or other proposed hatchery, someone from the relevant department may know ?  :popcorn)

Hi Graeme
I have worked for DPI&F or at least one of its forms for more then 21 yrs now, and have been involved directly with the stocking program and overseeing  the stocking of MRC amongst other things. I also worked with Don, say hello next time your talking to him.  At least in my time no Murray cod were stocked in the Mary and I have never found any records nor heard any reports  of them being stocked into the Mary in any numbers and trust me I have hunted, because these types of rumours have been around since Adam was a boy. All the genetic samples for the description of the MRC as a distinct species were collected long after Don left the Department, those involved with the Taxonomic work were aware of the rumours and found at least all those that were sampled were a distinct species and showed no indications of hybridisation with Murray Cod, so even if some were released they  didn't survive. Early results from more recent genetic studies have also found no Murray cod genetic mateial in any of the 100 or so fish sampled. The other part of your story that puzzles me is the movement of fish in bulk tankers on the rail system, to my knowledge we have never moved fish at least bulk numbers by the rail system, as it was always way too slow. I was told by the original DPI&F officers that commenced the Recreational Fishing Enhancement project that  in the early days of the stocking program those fish sourced from NSW were most often shipped in boxes in light planes.

Stephen, Murray Cod were stocked under direction from the Minister at the time into Boondooma, Fairbairn and an offstream storage on the Thompson River in the Lake Eyre basin. Those stocked into  Bjelke Petersen were supposedly MR cod from Abington Hatchery and I can't recall any going into Moondara but thats not to say they didn't.

I'd say this myth has been well and truly busted.
