queensland Brisbane River threadfin

[braddo]

Hi all you Bris River fishos. I'm working on a project at UQ looking at biology and movements of king threadfin along the east coast and am interested in getting some threadies from SE QLD, especially the Brisbane River. If anybody catches a king would it be possible to keep the frame (you can keep the fillets!) and catch details (with total weight) and give me a shout? I'll arrange pick up. Cheers

welcome to afo braddo. i've got a complete frame of one i caught 2 weeks ago in the freezer, destined for crabpot duty, you can have if you want it.

[fishingnut]

mate id just like to catch one, wouldnt even know where to start:blush:

[flatty_catcher]

No worries , awsome project mate BTW.

do you need more or will the one from jeff be enough? also wondering if you need it whole or is it fine if its cut in half?

[braddo]

I'm chasing a few fish a month for the next year, so keen to get any you might have. ideally i'd like frames with head, guts and 'nads (and fish length and weight) but we'll take what we can get...

cheers, brad

[jeff f]

brad is as good as his word too guys

no stuffing around

he was here to pick up my frame exactly when he said he would be

[noname]

a project at UQ hmmmm. does this mean the powers that be are thinking already about turning the river into green zones,, everytime i hear of somebody wanting frames etc, of fish, i always think twice about ANY INFORMATION, i am willing to give, but hey, i've got good reasons for this

[braddo]

mate i know where you're coming from, and its up to the individual if they what to help. The project comes from a purely fish biology perspective, in that i'm trying to fill in the many gaps in our understanding of the biology of these fish. Some of the big questions we don't yet know the answers to are at what time of the year do they spawn, at what age do they reach maturity, and whether they are 'resident' to areas or move around along the coast (i.e. if they're fished heavily in the fitzroy river does that affect fishing in the SE?). Thats what this project is all about.

I believe that this project and the one on tagged bass by David Roberts from Griffith deserve our full support.

The more that we know about these fish the better it will allow the fishery to be managed in a sustainable manner.

These projects only research the growth patterns, breeding and eating habits of the fish.

One project that I am dubious about and in fact have ceased to participate in is the one run by the DPI called recreational fishing diary programme.That decision was a purely personal one and I do not wish anyone else to cease participating.

Cheers

yeah a workmate of mine reckon the Fitzroy is muddy and once mentioned they use catch em by flicking your bait or lure at floating snaggs, he reckons they hang under floating snaggs for a feed.

yo braddo. i'm at UQ also, been dying to catch one of these threadfin so if your out fishing one day let me know i'd like to tag along and learn more about your project also.

[mobynick]

Any Idea if or when this report will be accessible to the public?

[braddo]

hi mobynick, we're just at the start of a 3 year research project that runs through to early 2011. Expect to see updates in the FRDC newsletter http://www.frdc.com.au/pub/news/. Also I'll post any interesting patterns or trends on the forum once we start getting some data

cheers braddo,

I`m sure many at AFO would be interested in following your research project

[tacklebox]

Thought I'd bump this thread since there have been a few caught lately.

Anything to report yet braddo?

[wesfish]

here is a question for you braddo , do you know what their eggs look like or what type of breeder they are ( mouth or other?) we caught a couple of sharks that were kept for dog food and when we opened them up they were full of orange hard eggs a bit smaller than a ping pong ball , we were wondering if they were thready eggs ,but no one knows what they look like , has any one tagged any of them with success of recapture?? or do you know what their growth rate is?

Strange, everybody seems to target threadies in the Brisbane river by night in deep water.

I used to live in the southern end of Broad Sound where threadies make up 90% of your catch.

The go up there was to fish the daytime run in tide in the week leading up to the full moon. The best areas were river mouths in close in to the mangroves.

Most of the fish I caught were in less than 2 metres of water and some less than knee deep.

Caught them on flesh baits, but live popeyes were the go for the bigger ones. I've commonly caught half a dozen in a 2 hr session using this technique.

Like I said, only in the week before the full moon. For the other 3 weeks I didn't bother wetting a line.

Down here might be different. Never tried for them here.

more than 50% of mine came from shallow sandy flats on the run in tide or last bit of run out tide !! day time and night time

Hey Wesfish, those eggs in the bullies stomach will be Catfish eggs. That's what they look like, and about that size as well.
