Fascinating footage highlights benefits of Release Weight
Fascinating footage highlights benefits of Release Weight
Media release http://www.recfishwest.org.au/MediaStateReleaseWeightDVD.htm
Recfishwest today launched the Release Weight DVD and information brochure to promote best practice for releasing demersal scalefish.
"The DVD includes some fascinating above and underwater footage of the Release Weight in action, showing fish clearly suffering the effects of barotrauma swimming off strongly with the aid of the release weight." Acting Executive Director of Recfishwest, Kane Moyle said today.
Recent changes to managing the recreational catch of demersal scalefish in the West Coast bioregion coupled with a changing ethos to catch and release fishing is seeing recreational fishers releasing more and more fish.
"It is extremely important that every fish released is correctly handled and it has been proven that the use of a Release Weight will significantly increase a fish's chance of surviving the capture." Mr Moyle said.
The importance of the Release Weight as an effective means for releasing demersal reef species has been shown through the Fisheries Research and Development Corporation, Murdoch University, Department of Fisheries and ANSA project, Maximising the survival of released undersize West Coast Reef Fish.
The tag recapture data from this study found the Release Weight to be by far and away the superior method of releasing dhufish. Recaptures were 10.1% for fish release using a Release Weight whereas simple release recaptures were 6.3%.
"Recreational fishers are valuing more and more every fish they catch, a fish released in a healthy condition is one that can spawn and have the opportunity to be caught again later." Mr Moyle said.
Copies of the DVD and brochure will be distributed to tackle stores around Western Australia. A copy of the DVD will be provided free with every Release Weight purchased while stocks are available.
Recfishwest urges all recreational fishers to view this interesting and highly informative DVD. The DVD can be downloaded from http://www.recfishwest.org.au/ReleaseWeightDVD.htm
This project was made possible thanks to funding received through the Australian Government's Recreational Fishing Community Grants Programme.

Great news Terry!
Absolutely fantastic to see the DVD finally out there Terry! Just downloaded and watched the first movie (I have a release weight and it was the FIRST bit of fishing gear I bought when I purchased my current boat
).
Congratulations to all on the video, and a special comendation to Gary (Lilley) for his comittment and conception!
This should go a LONG way into extended, not only the knowledge of release weights, but how, where and why to use them and folks actual use of them.

What I would like to see is
What I would like to see is a camera follow a dhuie once released on the bottom in different stages of barotrama.IE( blown eyes,stomach blown ect... )
I'm interested to see how it copes with the symptoms in different depths and how it copes after it comes off the release weight!Maybe watched for 5-10mins.
It could be a good project to try and record.Wouldn't be hard getting Rockpom to follow some fish down with a camera and then we could all see what really happens.
It could be monitered from the top, hooking and winding up a fish(on video) to see how it is retrieved from a depth(speed) and then watched on video going back down.
I'm sure if people can see first hand that the dhuie recovers well once back down they will take more care in the releasing of fish as well as the winding up!

The Queensland video is
The Queensland video is based on 15m and as we know the depth we are targeting our so called V-5 species is generally double this depth so it is irrelevant to our type of fishing!

Good idea on the 'follow down'.
Hmmmm, I wouldn't call it irrelevant Matt, just because it's 15m. I think the message is to the sell the awareness and use of release weights and I think the videos are therefore relevant and do an excellent job of that.

Colin 15m is irrelevant
Colin 15m is irrelevant for the way we fish over here.(as a general rule)
What I mean is for our type of fishing generally 30-50m for our target species this information is irrelevant as we know that there is a high mortality rate for dhuies in this depth but if we can see how they fair in real conditions going back into a depth of lets say 38m it may help us get an understanding for how to turn them around quickly to give them a better chance of survival.

Havent seen the video, but
Havent seen the video, but are we saying that the video is of QLD fish in 15m of water?
If so I agree with Goat that the relevance to releasing fish, particularly dhuies, in 30+m of water is questionable.

Yup true Goat
Yeah, fair point, as you say, the vast majority of our V5s, esp Dhuis are caught in well over 15m and actual footage showing the results would certainly be a benefit and hopefully dispell any doubts.
Mind you, as has been said before, there is no alternative to release weights.

WA made videos on the Release Weight.
The "Queensland video" on Barotrauma is NOT the main movie about the Release Weight. That main video was made in WA off Perth.
The "Queensland video" is one of the extras from "Gently does it" by Andrew Ettingshausen. The introduction to those (Listed as Part 3) explains it all.
Source of that:- http://www.recfishwest.org.au/ReleaseWeightDVD.htm
More about the West Coast research results from the "Collaborative tagging program and research for increasing the survival of released line-caught reef fish" mentioned in this video on http://www.recfishwest.org.au/TaggingProgram.htm
Any videos of fish coming up and going back as Goat suggested would be greatly appreciated.

I dont know if any one has
I dont know if any one has looked into the difference between the swim bladders of the V5 as they all differ greatly.
I would say that Dhu fish going by past experience have the weakest swim bladder of the lot.
As for watching or taking video "bring it on"
Mike Maccie asked me to do this but hasn't happened yet.
As for fish swimming away after being released I wouldn't be surprised if its just sheer adrenalin that they swim away at all only to hit the bottom like a stone once their remaning energy has been burnt up or Lactic acid build up.

sorry vent coming on, you want to make an ill informed outlandish comment like that rockpom, ya would want to have the proof to back it, We have one of the highest recapture rates in the world from any fish, if you dont believe in the release weight good, your right, but (deleted) dont comment on it, unless ya know the research behind it, if ya still dont believe it, (deleted), lots of others that need to know that a fish has a chance at least, instead of being on the surface with its eyes picked out,
if ya need to know more. RFW have countless recapture stats on their site, from ALL depths,

Ive been doing research and using the release weight for the last 8 years but the last time we used it we had tagged fish found on a beach due to barotruama and that was in 20m.
I would like to be proved wrong thats why I offered my services 3 years ago to mike maccie to do some vid work!!

Some fish probably do die
Some fish probably do die after an initial burst of energy but the stats show that this is, to date, the most successful way of releasing fish suffering baratrauma. Be our guest to come up with a better way of improving the mortality of released fish.
Personally, well done to RFW for the undertaking of this significant step in the education process

I have TH and unfortunately the ill informed minister tried to remove it altogether with out any research to back it up!!
My past time is spear"fishing"!!!
No baratrauma, undersize or fish type problems there!!!!
Its not a sport for everyone but thats how I control the the ill effects of damaging fish stocks by being selective.
Also give a great insite to how the underwater world really works,Vid is great but seeing it with your own eyes even better!!
As for the release weight it hangs on my bait board as its used from time to time when its to rough or murky to dive.
But I would like to see more of the lasting effects after release as crabs can pick eyes out just the same as birds.....

It wasn't to prove someone right or wrong just thought it would be good to get some deep water releases on camera and see what the outcome to be!
Everyone seems a bit precious about this topic when I clearly stated that it was only to benifit the survival of the fish!
A little bit more footage may help the cause guys!

I welcome this DVD and what it will represent. Good to see the FRDC Grant being put to good use. I've got my DVDs and brochures being posted today (thanks Con)
I would also like to see more ongoing footage as mentioned. Depth say, 30-60m, release a dhu and see what happens ie recovery to barotrauma symptoms!
I was planning to do that this season just for our own curiosity, ohh and get a cray or two also

Diving to 40m isn't a problem its just that you don't have much time once you are down there.
Wally, allthough I respect your expertise on this you are sounding more and more like Jamie C everyday (or is that the other way around ?)
Im sure Goat and all the rest of us want the same as you do (survival of the species).

I REALLY do hope that a lot of people respect your knowledge, comittment and passion.
OK, I can understand that you might (Do!) get frustrated about contra or ideas you've heard all before. But isn't it about 'winning' people over in a positive way? I would like to think so. Time will always 'reinvent' ideas.
Just because peoples passion is felt discordant to your own, isn't always a bad thing.
Sometimes a tap on the shoulder achieves a lot more than going for the jugular.
You can't hope for peoples unbridled attention by attacking them.

Focussed and not Personal
I don't want this to turn into a personal attack, the message I DO want to sell, is that there are a number of people within ALL the fishing forums that have a TREMENDOUS wealth of knowledge, there are people that have SOME knowledge and there are others just learning and others just watching.
How so much better it can be if all of these groups collectively get together, share different knowledge bases, experiences and perspectives in a respectful way and work together (never mind about the history! We're here NOW!).
Fishing wise, there is far too much at stake otherwise.

release weight
Dreamweaver,
Diving to 40m is not that bad but bottom times are limited and can be done quite easily on normal air. At 42m you have around 7 min bottom time without decompression. If you do a decompression dive then of course your bottom time can be increased considerably.
Nitrox also will not always give you the ability to do deeper dives but will give you longer bottom times and shorter times between consequtive dives. In fact it can lesson your depth by quite a bit.
All I can say is wait for the footage people - it is coming! Is something we all want to see and is on the table I promise :)
And Wally - your comment on the lets go to 70m, what was the point to that. Was there any need?? Tell you what - I will watch as you do the dive...

Sorry guys
RE; my comments before that got deleted, and rightly so.
I guess what I was trying to say in simple terms is:
You cant expect respect by abusing people into submission, if you want support Wally your gunna need to change your tactics or people will just go their own way as you seem to make it all to difficult.
I would love to sit out the back and have a beer whilst picking ya brains about it all in a real life atmosphere, rather than go the knuckle on a forum.
I've seen a lot of divisions amongst fisho's on C&R of murray cod with best practices and see the same shite going on here, same shit different channel.
I'm sure everyones best interest here is in the survival of Demersals (mainly Dhuies) and you guys are all very lucky something is actually been done before stocks get to the critical levels of my beloved Murray Cod.
Work together and stuff the divisions when the common goal is the same, every bit of input should be treated with respect.

Interesting topic
Im far from an expert on boat fishing, releasing fish under the influence of Barotrauma, or even catching them for that matter. I just find this topic very interesting, due to some of the points outlined by people in there heated comments, and retorts.
Is there any other alternative to release weights for releasing undersize fish? Whilst the DVD supports the positive results of release weights, from what i see and read, the true survival rates aren't super high. Now i understand there may be no other way to release fish than using release weights, that will increase there chance of survival. We know, by the re-catch stats that the mortality rate is high, and there is an increase in the stats using release weights, but maybe its not the answer to a sustainable fishery, but a temporary solution to hold back firmer, stricter fishing rules, such as closures etc that result from a negative public opinion. So in a sense, the DVD is promoting the only suitable way currently available to support and sustain the way we fish for deep sea species like Dhuies. I would think, we all should be supporting it totally.
So theres no denying that R.W. do increase the survival rates, but a better solution must be found. What about things like a minimum hook size? Please excuse my lack of knowledge in this area, but i am a keen fisho, trying to read between the lines.

Yay, Wally threads are back again, great entertainmainment during those long nightshifts. I must admit it's a bit hard to fill those in newer on the scene (like myself)and share info and opinions when your getting farkin' told exactly how it farkin' has gotta be, I believe this is a forum so making comments that you believe may be true or have an element of truth is what it's all about, gettin told to shut ya farkin mouth cos ya don't know what ya farkin' talkin' about is the opposite of what it's all about.
Release weights - best idea so far
Release weights video - Good
Monitoring fish after deep water release - Fantastic idea

Release weight research and info
Just to help get things back on track,I was just (again) reading through Collaborative tagging program and research for
increasing the survival of released line-caught reef fish.
Under Interesting Facts, and I quote 'The deepest recapture of a dhufish to date is 90 metres released using a release weight (shotline)' - this would suggest to me that release weights DO work, and....
Under Dhufish recapture rates (to early 2006) the percentage recapture, via the 'simple', 'vented' and 'Shotline'(Release Weight) methods, the latter had the highest recapture at 10.1%. To me, this doesn't represent an almost 90% mortality rate, only that (simply) 10.1% were recaptured.
Also, Release Weights Back on the Menu, and in particular, Shooting video for the Release Weight DVD, certainly makes for good reading.

More than just the Release Weight
Colin
Thanks for posting those links.
There are other reasons for mortality of released fish, eg deep hooking, handling, etc - see below.
Info-fish website "Released fish survival - Gently does it" http://www.info-fish.net/releasefish/ has heaps of information.
The DVD and the RFW website have extra video segments from "Gently does it" (made for FRDC) by Andrew Ettingshausen which should interest people who fish for other species.
Source of all that to download any/all of the videos:- http://www.recfishwest.org.au/ReleaseWeightDVD.htm

Your welcome Terry...more
Yes, the Deep Hooking Fish was very interesting, particularly circles verses 'J's.
When viewing Samson Fish though, I noticed that there appeared to be a tendancy to 'spear' them in the water by just holding them inverted by the tail, rather than supporting them. As per Catching and caring for Samson Fish page 7, and I quote - '....and never lift the fish up by just the head or tail'.
As you say, so much more than 'just' release weights.

And Wally - your comment on the lets go to 70m, what was the point to that. Was there any need?? Tell you what - I will watch as you do the dive...
Ya Dont need to dive at all gully see link . edit click on the yellow eye release on the page ( pic)

Then all ya have to do is send down a camera to monitor the fish, because ya have the coords of where ya released it, of course you would want to send the cage down on a nice homely lump for him so he could hide for a while.
As for me and rutar, well spent a good hour explaining my frustrations with all this last night, i think he understands now where i am coming from. and thats exactely what it is, frustrations
put ya self in my shoes. i never wanted any thunder, just the fish taken care of, a jewie back in the system is a jewie in the recruitment bank. instead of on the surface with its eyes picked out
What really is needed here is a more vigourous tagging study with bigger jewies in deeper water.Fisheries and the Aliance ( now) wants to remove the min size, all good out deep but what about heading north where most of these fish are nailed in shallower water, and then ya have the implications of this flowing on to other species across the whole state

Good to see-
that you divers are showing a bit of passion for what is a very admirable project. Personally i get the bends in the bath these days and you ALL deserve a pat on the back in my book.

Personally i loved the Vid.
Personally i loved the Vid. Having just bought my first release weight and having now set it all up it was good to see how it was actually used. I speak to fisherman all day and honestly there area allot of different ideas on getting fish back into the water but the release weight is simply the best I've yet seen and good on those for there involvement.
As for the video side of things it would be good to see but i don't think it will show anything different than what we already now. Whether it be in 15 mtr's of water or 50 mtrs what i think the vid is showing is how easy they come of the release weight and for me i was happy with the 15 mtr shots.
As for Wally and his passion it is sad that it comes out the way it does but as I've said a thousand times its just a shame how it gets put out there. I'd personally love to learn more from blokes like you Wal and Garry because I'm the type that loves to ask for help but unless you can change your approach you'll find no one will still listen.
Good on all those involved and thanks for you for thoughts all those years ago

Nice watching a vid and feeling warm and fuzzy
I tend to disagree Rod by implying that a jewfish caught in 15m, 22m, 42m or on the shelf in 80 m would all swim away happily. It would just be nice to know that a jewie caught in 40m swims away and survives and becomes a part of the biomass. I think that as a genearal rule, that 38m-45m would be the general zone most bottom bouncers target, not 15m.
Im sure the pinks dont have a problem, but the jewies i don't know. Totally agree its still better using a release weight than watch a jew float away into the wilderness.

But see i think the point is only about the release of the fish. As for wether or not they survive well i would only say that the research that Wal, Garry and RFW have done does show that the fish has a better chance when released with a release weight. Thats just facts and figures. As for filming a fish being released at 40 mtrs that won't really give a good idea of mortality, for to be true reseach you would have to film many fish being released not just one to give a better summary. But that is a little of track sorry.
I agree i would love to see more footage of fishing beeing returned but you are asking for alot really so if anyone on here goes out and does film it i'm pretty sure everyone will be interested in seeing it.
Hope that clears up my thoughts

i think
that what ever we can do to get these fish back safely even 1% let alone 10% more by using the release weight etc is better then doing nothing and letting them die ...

recovery!
With all the people wanting to release dhufish in 40m and film it (document), we would get a very good picture and see quite quickly on how the survival/recovery to barotrauma symptoms would be!
Definatly agree that fish released in 15m of water versus 40 would be different!

Its great to see, definately has to be more effective and better to the fish than venting.
I'm not going to enter the discussion from a research perspective, but good to see some progress in terms of informing the masses.
