Looks like they've approved the outlay of $81,200 to see if they can screw up a perfectly good fishery.

So when Jacks become more broadly available for stocking in Qld you wont want them going in any existing bass fisheries because they may screw up the fishery  ::)  - I doubt they would anyway....

I'm sure the fun police at SEQWater wouldn't allow them in their lakes because once they hit 20lb they'd be a danger to the swimmers.

Wyaralong could be the perfect spot for them.  No swimming so they won't eat the kiddies.  No real established native angling species.  (Some Bass and Cod present.)  Ample population of feral forage species.  The Dept of Environment could fund it jointly with the Dept of Sport and Recreation as a Carp eradication/Recreational angling program.  Could be a Tourism drawcard for Beaudesert as well as a great experimental site without a drastic risk of ruining an established fishery.  Throw a few million in there and see what happens.

 Wyaralong has spilt nearly every year since it was built. As Elops says they bugger off over the spillway at the first opportunity that would make Wyaralong to be a poor choice.

As Awoonga has stocked them in the past, what are the catch results there given that Awoonga has spilt nearly every year since 2010?

Why get rid of Forkies, they're native and belong there more than Mary River Cod, Golden Perch and Silver Perch.

I think Clarrie Hall spills fairly regularly as well Dave, maybe it's a good time to develop a way of retaining fish in a dam that spills.  I remember some crackpot a few years ago wanted to put a net across the wall at Awoonga to retain all the Barra in the event of a spill.

Its not such a crack pot idea to have spillway exclusion nets for barra, they work fine on a number of nth Queensland impoundments, re: Mary Cod which is just one name used for a species complex that occurred in all basins from the Clarence north to the Mary incl. Richmond, Logan, Albert, Coomera, Brisbane and Mary - they have some historical tenure on the place - at least more than silvers and goldens and inland Jacks - predation (at least from natives) would not get 'rid' of forkies, but may moderate their abundance which is likely to be unnatural in the absence of the native predator suite (incl large cod) and in the presence of abundant artificial habitat in the form of impoundments

Also maybe its not such a bad problem if Jack do spill into receiving river systems - especially if their stocking was paid from a general rec fishing licence (as it is in NSW cf. the SIP scheme) and spilled fish contributed to river and estuarine fisheries....

I guess it's academic now,against the wishes of the dam's owners and stockers the first batch were released today.
