100 tags
Submitted by Paul G on Tue, 2011-07-12 21:52
Headed out with Jody this arvo for a quick fish .tide was running from the North so I didn't expect to get a lot but I was wrong .We started fishing 3:30 and two hour later had tagged 11 dhuies and kept one also two snapper and a baldie Also Recaught 2 tagged fish ..But as soon as the sun hit the water things went quiet. What a great way to finish the day and tag our 100th fish .Bring on Sunday.

well done paul u really got
well done paul u really got those duhies sussed and so good to see that u are getting the recaptures just curious as to what depths your recaptures are coming from wondering if the fish in 40-100m have the same survival rate.

Congrats on the ton Paul and crew. You guys are sure doing your bit as far as conservation/research goes and I enjoy reading all your posts. 10 recaptured shows that you must being releasing them well and that Dhuies can survive being caught and released. Well done again!
I fish for the future - Cause I can't bloody catch anything!

10% recapture rate is pretty good, goes to show there is still some good numbers of fish around.!

Paul,Well done on the 100
Paul,
Well done on the 100 tags and the 10% recapture rate. Of the 10 recaptured were any of them vented and how many were free released as opposed to release weight. It will be interesting when we are able to get a clearer guide as to how best ensure the survival of released dhu's. Maybe fisheries could fund some workshops to promote best release methods.
It would appear that you are having a greater success than when fish were dropped back down in cages.

I have to get my crap sorted and get on the board
a bit more.2 and a half weeks left and im back in the game.Then it will be catch up time
Well done Paul and crew i will have to come a bit further out of the way and see if i can find a few of yours
So tell me have you got your info from years on the water or hours on the internet?

90% of fish to date have been
90% of fish to date have been vented .I will now stop venting for the next 50 and see what happens. Yes very happy with the 10 % recapture . Im sure I will get plenty more over the next 4-5 months Thanks for the posative coments .Wil put up the data on growth rates ,some fish have grown 20mm some only 5 mm .the plot thickens

Hey Paul
Hope your well, haven't seen ya since i left the industry but I am interested as to why you would vent a fish from 32-40m.I would have thought that at that depth the simple release would be fine - so long as a slow retrieve was used on capture.
Certainly not having a dig at ya buddy as you are doing a great thing getting this data - but just wondering if its a personal call or something more?
The recaptures i got off 30 odd tagged fish in 2010 were at around 30% with a simple release and slow retrieve, min handling, time out of water, out of sun.Only Sat just gone i had another recapture #21058 - (well RyanC did on my boat) of a fish that has been out since 10/03/10 and was originally 40cm, now 52cm and still swimming in 38m - simple release, so grown 12cm in 15 months.Funny caus we were just talking about recaptures at the time.
heres an excert (minus gps marks) from my tagging pages on one fish that became a yoyo......
21083 – 47cm tagged 10/11/08 simple release – RECAPTURED 06/01/09 49cm simple release failed then shot-lined partial stomach protrusion fin and ray movement ,no exopthalmia evident upon release. – recaptured 01/04/10 healthy fish 55cm moved to waypoint 40 and kept.
I stopped tagging after that - felt that the info i was getting back answered my own personal questions about post release survival.
Movement was interesting too, lots of movement in smaller fish under 60cm.
As a general rule on the good ship - anything suspected of being a dhufish is treated with care and retrieved super slow - then,if it looks ok - ie no stomach out of mouth,eyes ok (no exopthalmia) etc then simple release.However if its not looking as good, no movement and stomach out - put it straight on a release weight and they are ok too - lots of recapture details for that too.
once again good onya mate!!!!!
Cheers Joffa.

Working late tonight hey?
I was going to take your boat for a spin this arvo as it looked lonely when i came past.Was it a relation of yours that went prawning on a paddle board?
So tell me have you got your info from years on the water or hours on the internet?

Hahhahahaha
Yeah, that was my brother who really wanted to go prawning and when I pulled out he went down "other" avenues.
Did alright, 50 or so in a couple of hours - he reckons he spent a fair bit of that time being laughed at by passers-by but "he who has the Prawn sanga" wins.He did it safely mind you - he wore his reflective vest and the water police reckoned if it wasn't soo bloody absurd there would probably be a law against it.
Boats all yours, thats if you dont mind fixing the wheel bearings before ya go.
Cheers Joffa

It is just the way I have
It is just the way I have done things I guess its a personal thing .Have caught one dhuie three times all times he was vented .Am going to release the next 50 or more without venting .We have had Two fish tagged the same week recaught one has grown 5mm one has grow 20mm that was a bit of a surprize .but all fish recaught seem to be in good health with no sign of being caught before. All fish are brought to the surface slowly most only have a swollen stomach.Every now and then one will have the stomach in its mouth .They will be sent down on a release weight .

Onya Paul
My only point there is that with soo many on this site looking up to you i just wanted to say that in my experience both first and second hand I wanted it in writing and very clear that - for the average fella wanting to do the right thing, maybe forget the venting thing.....thats until we know what the preferred method really is...way too easy to fug it up.
Good on all of the FW crew who have helped with this program....hats off.

You say in YOUR experience
You say in YOUR experience .You tagged thirty fish to saticfiy you own personal questions . Then stopped tagging well done big effot mate. You don't read to many posts of mine or you would know I discurage venting .Yes it is easy to stuff it up . from your data the only thing saticfide was yourself. I and others have caught fish with old tags and no data is recorded .Sounds like you guys did a terrific job at boasting your own egos . could have something to do with the old data being of no use .

I agree.
You got me wrong, i was told to start tagging and got told to stop mate, due to the info not going anywhere at that time.
I was just trying to help mate, just like you.now.
The info is there complete for anyone who wants it.just pm me with a email address.
To clarify i was "satisfied", with knowing that at least some dhufish are actually surviving release (as i would have originally expected) - as there was debate if they even survived at all at the time of being asked to whack tags in.
anyway off topic but to reiterate - I applaud what you and the other crew are doing, no hassles there, just that venting wasnt an easy task and one that might not be good for people to practise who are not doing this study...for the fish's sake.
ok.

Roll on 2000 tags - the
Roll on 2000 tags - the Dhufish tag target, a target for the required data to build reasonable data models for experiments.
While many anglers would keep size Dhufish, people like Uncle who really were drivers in the tagging early in the program releasing many size plus fish, Paul has tagged and released lots of big fish.
The biggest issue Paul has with really big fish is having enough weight to get fish with expanded bladders back down; bordering on using an Alvey winch the weight required is really heavy. Many of Pauls are really big fish.
The goal of the program has always been a range of release methods. The reason for the range of release methods is to establish the model of what happens to fish when they are released in a different manner of method. So the release methods can be, simple, release weight, vented. Even the hook styles are part of the modelling in mortality study. Numbers are needed in all different methods for valid modelling. 2000 is a little golden number for modelling.
If the all the fields are not filled in then 'some' scientists will not use that particular data for their modelling as the data is redundant for their particular modelling.
As a national data modeller said, as the numbers of mangrove jack were tagged the model changed. That was 15 years plus ago.. A lot has been learned since then..
If you capture a tagged fish, you are welcome to keep it, reporting the recapture data is important.. A wonderful thing to give back to the environment..
Data integrity is everything..

While some anglers think tagging is destroying their future, it is the complete opposite..
Without tagging scientists have to do a lot more assumptions..
