I noticed some years ago that after we introduced Snub Nosed Gar to Lake Somerset, that in the following years the extensive weed beds there seemed to disappear at the same as the gar popluation exploded. The gar went through a boom-&-bust cycle there then settled down in a more consistent population.
With Cabomba caroliniana weed in (I believe) Lakes Kurwongbah, LaccDonald, Ewen Maddock, Cooloolabin in SE Qld, I don't think that these lakes happen to have snub nosed gar, while the weed hasn't managed to spread to those lakes that DO have snub nosed gar.
I've often wondered the trialing snub nosed gar as a cabomba weed control agent has been tried or considered?
What do you think?

PRFMA introduced gar into Kurwongbah several years ago but I have no idea how they have survived.

Prfma had a few goes as putting Gar in to Kurwongbah, but none seem to have resulted in the sort of Gar population seen in North Pine.

It took the Cania Dam group 5 attepts to get gar to take there. We got it first hit in Somerset.
-
Pest management at MBRC want to trial them in one of there suburban lakes.
Doing a another translocation into Kurwongbah in the next few weeks.
-
Used to have Gar on our permit for Caboolture lakes. Think we tossed them off to allow for Mary Cod.
-
No reason why you could not get a translocation permit if you wanted to Andrew.

Would be very interesting ... Maroon is one of the worst dams ive seen for cabomba not that i have seen extensive amounts of dams but it is pushing out from the banks at least 30 sometimes 40 meters offshore and bays are completely swamped in them making them near impossible to fish unless 100lb flipping gear is used.
Im pretty sure Maroon does not have snub nosed gar or boney bream ... even tho there are clouds of firetail gudgeons they are too far down the food chain to look after the cabomba..
Go have a look Fitzy i think a trail should be run even if only in few thousand ltr tanks downscaled

Cabomba in Maroon ? have not been there for awhile only saw Elodea.
-
It's bad in Clarrie Hall as well, and getting worse. That dam is owned by Rous water tho. Have no idea what they would say.

Cabomba is a weed of National Significance, therefore is eligible for funding under the Federal Governement's CFOC program http://www.nrm.gov.au/funding/index.html (http://www.nrm.gov.au/funding/index.html)
Would be a nice little project for a group to pick up on providing there was some anedotal info to suggest that the gar may actuially have some impact.
An isolated dam, not too big and not to thick of weed would be a good start.
Funding call finishes in early Feb btw

The introduction of gar into cressbrook saw the disappearance of shrimp to the extent that live bait fishermen ignored th law and caught shrimp in perserverene for use in cressbrook I'd hate to see gar turn in to the cane toad of the water
They are a pain to fly fishermen
-
Be more inclined to point the finger at Redclaw for some of the massive reduction in macrophytes in a few of the SEQ impoundments rather than Gar.
-
Aussie Basser do you think the number of gar has decreased since cressbrook filled? I use to see heaps but i havn seen as many of late and wonder if you think that also. Was an unreal amount before the floods. I dont think they made much of a dent in the shrimp population as i know people getting heaps of shrimp before it filled. I think the loss of weed beds is more to blame for shrimp loss.

As far as I know its only an SEQ water rule you cant move shrimp, not law, you can legally use them across all locations they are found in despite where sourced.
As for cane toads of the water, that would be barred grunter and spangled perch, bait stealing mongrels they are! When it comes to bait stealing Gar are only an issue for Tilapia fishermen ;D
-
Binder, there is a no shrimping rule at perserverance that aussiebasser is talking about i think. It was brought in years ago there by the council. Like ya said shrimp can be caught anywhere an used im pretty sure. Thats why you can still buy them in shops unlike yabbies.
-
I haven't bOthered fishing cressbrook since the rangers decided to try to discourage visitors by bringing in One law for visitors and one rule for locals The shrimping rules at perserverene may have changed
-
Yer agree with you in some ways aussie but im a local and i can tell ya it doesn matter who ya are. Treated the same. Years ago it was called the no no dam for a reason hey. I dont fish there stuff all anymore. I prefer to drive right past the front gate on my way to somerset. Rule on shrimping still applys at persy.
-
Not sure on the Gar eating the weed. Maybe a certain type as Lake Gregory has heaps of the stuff and is teaming with snub nosed Gar.
cheers
