Plenty to talk about on this I'm sure.....

Since the size of Snapper has been decreased from 1st April how are you finding the new Regulations ???

1.. wastage, are you killing more fish by having to return to the sea that would of been legal prior to 01/04/2014 ?

2.. Would you have kept those fish if the new size had not been brought in ?

3.. Are you able to catch a feed of snapper without killing many fish sub 300 to 270

With the new season about to kick off ( when the weather allows ) Everyone will be out fishing , I'm picking this new size will result in wholesale slaughter of perfect eating fish ,Commercial are allowed to keep from 25cm
We Recreational fishers could now be classed as bad as Commercial for wastage ( but in fact worse as they keep the sizes we throw back...

How many hundreds of tonns increased wastage is this new size adding to an already stressed fishery ?( which was not the case in the past )

Are MPI going to further reduce our allowance because of this ?

4.. Do you think the size should be brought back down ?

5.. Should our size be reduced to 250 in line with Commercial ( thus reducing recreational wastage ) ?

Any talk about Increasing Commercial sizes could only happen with compulsory net changes !!

6.. Inner Harbour Fishers could be the ones most affected by the changes that occurred ?

Good solid feedback would be most welcome to the above

Well, for years our family standard for snapper has been to keep the ones between 38-65cm, and that's what we intend to keep on doing. We do occasionally keep bigger ones when in competitions, and I keep down to about 35cm when fishing ultralight.

And I cannot recall a time when anyone in our family has brought home more than 6 fish.

So the new regs make no difference at all to us.

By and large, we fish <25m for snapper.

My limit has always been about 35cm. Mainly take 2-5 fish per session can't say I catch too many illegal fish and if I do its in the shallows. New rules have not affected me but I can understand why guys are still miffed at them. Commercial size should match ours in reality 27cm for all.

I'm definitely killing more 29/30cm fish. The reduced size was a ridiculous idea. I dont like keeping any thing under 32cm now cos I'm sure the buggers shrink a cm in the slurry lol.

300mm has always been my minimum.Bag limit has never bothered me as we dont like fish that has been frozen for more than one week .Giving fish away is the best part of any fishing trip!

The size and number of snapper I keep depends on 1) How many I have to feed when I get home and 2) where I'm fishing (depth). These days most of my snapper fishing is sofbaits in under 20m and as they're almost always lip hooked, no probs releasing a few if I'm are hoping to biggy-size the catch. The good thing about softbaits is that generally the fish seem to be a bit bigger anyway. I don't freeze snapper as that ruins a perfectly good excuse to go and get a feed of fresh fish regularly.

So no increased wastage but the commercial min length should be the same as rec, no question. The bigger issues are how we can ensure those smaller snapper caught in nets survive and rather than focus on our share of the snapper pie, how we can increase the size of the pie. Fighting over the share of a diminishing share of the biomass is a bit pointless.

Size limit increase has not changed what size snapper I take home, always kept 3ocm plus anyway.
When I go fishing I take my limit of snapper more now than previous and also now seem to be utilising a bigger variety of species to supplement catch.
I fish shallow and handle released fish with care but have no idea what survival rate is...
Pretty sure the fish I release have more chance than an undersize squashed in a trawl net though.

27cm should be the minimum size for the commercial and recreational fishermen.  I am sure that this would help reduce juvenile mortality.  I would like to think that most of us on here handle our throwbacks properly but i imagine there would be alot of other fishermen out there that would not

NUMBER OF SNAPPER TAKEN IS MORE IMPORTANT THAN SIZE !!!

THERE IS A GOOD ARGUMENT FOR NO MINIMUM SIZE FOR SNAPPER.

WHAT IS WORSE FOR SUSTAINIBILITY - SOMEONE TAKING 7 X 25 CM SNAPPER OR, 7 X 45 CM..

25% OF RELEASED UNDER-35CM SNAPPER DO NOT SURVIVE

Ban trawling and purse seine netting for snapper - long lines only for commercial.
The increase in size limit has not affected what I keep - as there is not enough on a 27cm snapper to make it worth while - even kept whole and cooked. Commercial size should be increased to at least 30cm, preferably 35 cm. How many released fish survive I cannot say - but none of them survive the chilly bin Wink

I DO NOT 'PULL STUFF OUT OF GOD KNOWS WHERE'.

Released fish mortality has been a concern of mine for many years and my research has been extensive.
The only study I found of any value was carried out in Kawau Bay, Nov-Dec 1995 by NIWA under contract to M.Fish.
216 snapper from 17 cm to 33 cm were line caught by local anglers, released into a large sea-cage and monitored for
15 days. 25% did not survive.
The very detailed report was released in July 1997 under the title Project AK717.

Whilst a Fishery Officer I privately recorded not only numbers of snapper taken but also numbers of those released. Over a 5 year period, in the Hauraki Gulf, the result was 4 snapper released for every one kept.

I believe mortality is very much related to depth and how hooked...
So self imposed say 35 cnm fishing say 20+ means a high death/ wastage, regarles of size.
Therefore any caught over 27 cm should be kept in the bin, if blown
As it a 27 cm giving small fillets....If one takes a bit of pride in how they fillet rather than speed, a 27/ 29 gives a reasonable ladies/ child size feed.

But to legistate for depth, size etc let along enforce would be impossible.. and its a total waste of time having laws that are not enforcable  .. usually because of loop holes.

The biggest issues are the commercial regs... well the ppl who set those regs... not the commercial guys....
1/ bottom dredging trawling , descruction of feeding grounds/ spawning grounds has to stop... we are re ploughing over grounds time and again and have been for at least 50+yrs.
This destruction of shellfish grounds has resulted in the Harbour/ gulf now having a muddy , dead bottom.....And destoried all natural filtering of run offs....
2/ Run off.. not much can be done, but most of this could be taken up IF the natural filters had not been destroyed....not degraded... destroyed
3/ no quota limits on bait fish, mullet, KY , king fish....all an esentual part of an over all system

We are complaining about snapper, and other species now... YET we seem to forget these species are just the 'next in line' .....the hapuka of the back of the noises , gone, the tuna gone, the huge pipi/ cockle beds , gone, the crays, near gone... well we have already lost more than what is left

And noticed the price of fish in the last 12 months....basic law of supply and demand
Snapper has gone from just under $35/kg  to near $45/kg.....and other species not much different... except carp

The owner of a fishing charter company in the Hauraki Gulf says the new size limits for catching snapper are threatening the future of the fishery.

The minimum size limits for snapper was raised from from 27 cm to 30 cm.

Ministry for Primary Industries raised recreational fishers' minimum size limits for snapper from 27 cm to 30 cm, in April this year.
They also dropped the bag limit from nine to seven snapper per day to help the fishery rebuild after over-fishing.
But Andrew Somers from the Red Boats charter fleet said it was having the opposite effect as shags are swooping down to eat the under-sized snapper as soon as the fish are returned to the sea.
He said it was also unfair that commercial operators were allowed to catch smaller fish than the recreational fishers.
"I think the fishery is highly at risk, I think we are heading for a major problem.
"It was going to restore the fishery and provide fish for our children and grandchildren so they could go fishing as well and if we just keep killing fish as we are, that's just not going to happen."
An MPI spokesperson said the impact of shags will never be a large enough factor to effect sustainability of the snapper population.

Last weekend I was trying to shoot the little snaps snaps down under the boat quite quickly but the shags still got them. Weird as. Cant ever remember it consistantly happening to me before.

There have been a number of other studies on caught snapper mortality since 1995.

During November and December 1995 Project 717 study was carried out off Moturekareka Island where 216 under-35cm snapper were taken from depths of 14-20m. The fishers were local volunteers with varying experience. One group were told to handle the fish as they normally do and a second group given 'best practice' instruction, the intention to achieve a true average. The snapper were tagged then released into a large holding tank with circulating water. Every hour the fish were transported to a nearby 20mx20mx10m deep purse sein holding net situated in 15m deep water. Fish were monitored twice daily, dead fish removed and details recorded. After 15 days remaining fish were removed and assessed. 54 of the 216 caught and released snapper did not survive their injuries.

The anglers were given 5/0 Wasabi J hooks on a one-hook rig which is what most use today.

Had barbless circle hooks been used most fish would have been lip hooked and the mortality rate around 5%



Hmmmm... times have changed in 20 years.

These figures are more or less consistent with other studies, and fishing practices have changed so that far more people are using circle hooks than in earlier times. In addition, the almost universal anecdotal evidence from softbait and slow jig fishers is of pretty much entirely lip-hooked fish.

A bald statement that 25% of caught and released fish die is likely inaccurate these days. If the point of trotting out this percentage is to argue that they'll die anyway, what about the 75% that will survive on these figures?

Most of the studies have actually involved very large proportion of small snapper, such as this one with only sub-35cm specimens. On other species, size and also stress in capture and handling are also shown as determinants of mortality in catch and release. Snapper are unlikely to be dissimilar to other species.

Depends on depth of water caught in, length of fight (ie lactic acid build-up), species (eg kingfish are more resilient than snapper), and handling (most people find it easier to handle a large fish without crushing gills etc than small fish).

So no simple answer, Daz, but in general larger snapper will manage release better than small ones. But the 75% survival is a figure to hold on to, even for the smaller ones.

i think snapper are way different PJay, not quite as bad as Harpuku but nowhere as good as Kingfish Kahawai for releasing...

its back to the drawing board till they work out a formula,
what depth it was caught at,
what speed it was wound up at
what condition the fish is in when caught,

even lure caught fish from a depth of say over 20mts is going to have a problem,
it may sit on the bottom with very little movement till the its body adjust to the ordeal its just been put through and while this is ok it is vulnerable to attack by other fish including sharks/kingfish/rays even congers eels,
there are lots of scenarios which could cause this released to not make it,

the real point is though the higher our take size is, the more likely hood of fish that are going to die...
releasing fish with all the benefits of wet rag/wet hands/large size hooks/re-curve hooks/held right/ will never stop the fact its internals have been damaged to an extent, plus the recovery time it spends has it been turned into fodder for something else to eat....

ive watch may of the large fish been released on TV and have never been convinced they all make it, some have not looked good but then they quickly change to patting each others back, when some of these divers could hit 15mts easy yet they never go that far to show you the real truth, or maybe they do but dont want to show us the results because that would make them look stupid,
yet many on here i am sure know that they come back up again and flounder on the surface behind the boat...

you could use them here as well, all it means is another journey of the unknown,
you ever seem a diver leave the surface to 30/40mts then descend very fast because he panicked?
similar problem except in reverse, i can just imaging a snappers guts turned inside out by sending it back into the deep at speed, if it had problems with the ride up how do you think it would love that ride back down when it had half adjusted itself to surface pressure????

33mts is classed as one atmosphere:
in other words you take a one liter empty bottle with a cap on it down to 33mts and it will be half that size,
do the opposite and bring a bottle of air up from 33mts it will be twice the size,
in other words your snaps guts and air bladder will have doubled in size including any air in its blood will have doubled, its air bladder doubled in size is likely to have burst, the amount of bloody would have doubled in size, any air in its stomach would have doubled, plus any hole in its fillets bones would have given it a very disturbing trip up then back again....

so even looking at 20mts that fish is going to have over half of the problem that fish from 33mts had,

the fish would be better off treated once at the surface with a needle then released in shallow water to works its way back down at leisure without going through another ordeal...

Caught a snapper in 90m the otherday swam back down just fine.

The argument that going down is as bad as coming up is load of bollocks, when a fish is blown re-compression is one of best things for them.... yes I have swam down with a visibly blown fish to see what happens... used to keep Hapuka in tanks at home for Niwa brood stock anything sub 100m that hadn't totally exploded on the way up could be kept alive in a 2m deep tank.

I am talking about recreational caught snapper released into a nearby environment similar to that in which
they were caught.

Right on pjc !!   


For many years, until about 2006, the rule was if you choose to release a legal size fish it must be accounted for in your daily allowance. M.Fish abandoned this rule and when questioned they said it was too difficult to police. Of course it was, even impossible, but what they could not comprehend is that A SENSIBLE RULE DOES NOT ALWAYS NEED POLICING.
Many of us still conform to the old, sensible rule - especially since the minimum size was increased to 30cm.

Oh, here we go again, Murray.

That was not the rule beforehand, never was; but a very small minority consciously misinterpreted so much that the law was clarified. Clarified, not changed.

But I still don't get the logic in "kill every small snapper you catch other than undersized ones".

PS, Murray: as I have repeated and quoted these in other threads before, and a simple Google search will get you to them: there are plenty of other studies on caught Pagrus auratus mortality.

You do have a point that the apparently unpublished and certainly non-reviewed report you mention so often is the only one that used entirely non-scientific amateur personnel to do the catching - apart, that is, from the Auckland/Northland/Bay of Plenty study on recreationally caught snapper the Ministry did in the late 1990s that was limited to surveying the incidence of gut-hooking snapper on "J" compared with recurve/circle hooks.

considering you should have a lot more idea than most Josh i find this statement very far fetched,
one there is no way you would have know if that snapper would have survived a trip of 90mts,
and the Hapuka in the NIWA tanks where more than likely vented before being release into a tank.

i might have to eat some humble pie here...

well here is an interesting article with studies on the survival rate over a couple of days,
even so they are still not sure how many die after being released over a longer period....
so the verdict is still out, not fully solved....

here is another site,
Snapper Survival rate from MPI NSW,

67-92% Key factors for fish mortality "Deep hooking and poor handling"

now they don't give any scientific research on how they come up with these figures but at least its not as bad as what i would have predicted the mortality rate at....

this report also went into hooks swallowed and line cut before release...

i still need further convincing as this should involve deeper caught fish like we are experiencing with work-ups out in the gulf...

Agree Josh

The studies on Rockfish in the USA found that rapid recompression was the best treatment.
They had Pressure tanks on land to simulate decompression, short time at the surface and recompression then observed them for weeks and most survived even though the swim bladder was burst. Snapper are tougher than Rockfish.

This was a surprise to me.
A peer reviewed paper. I have not seem the full article.



Surviving the effects of barotrauma: assessing treatment options and a ‘natural’ remedy to enhance the release survival of line caught pink snapper (Pagrus auratus)
M. F. McLennan*,
M. J. Campbell and
W. D. Sumpton
Article first published online: 20 MAY 2014

Abstract
A new technique to ameliorate the effects of barotrauma was tested based on observations of pink snapper, Pagrus auratus (Forster), inadvertently piercing their everted stomach with their teeth and releasing trapped swim bladder gases. This technique was termed buccal venting and involved piercing the everted stomach protruding into the buccal cavity or out of the mouth with a 16-gauge hypodermic needle (a practice previously not encouraged). Short-term (~3 days) survival of buccal-vented fish was not significantly different from laterally vented fish nor untreated controls. Both buccal and lateral venting techniques were shown to cause no harm and allowed fish to return to depth. The short-term (1–3 days) post-release survival of line caught snapper was 88% with no significant difference in survival across three depth ranges tested (37–50, 51–100 and 101–180 m). Survival of sublegal pink snapper (<35 cm TL) was not significantly different (P > 0.05) from that of legal-sized fish (≥35 cm TL). Healing of the swim bladder was observed in 27% of pink snapper dissected after ≤3 days in captivity, and healing of stomachs was observed in 64% of pink snapper that had been buccal vented. Relatively high post-release survival rates of line caught pink snapper may offer some protection for snapper stocks where high fishing pressure and legal size restrictions result in the majority of the catch having to be released.

I don't see what is far fetched about it, right I got no idea if the snapper survived it was ok on the surface and swam back down out of sight under it's own power, maybe there was shag down there that got it?

Yes hapuka were vented.... we even threw one off the retaining wall once, it was flapping around the lawn with the dog licking it....I think that one is swimming round in KT's now.

 Point is if they can survive a one way trip to the surface long term, would it not be reasonable to consider chances of long term survival maybe better on two way trip, back to bottom (given the depth relieves the effects of barotrauma... something that venting wont do).

hahaha Josh, yeah the shag bull on FBook now that is a joke...

that is very interesting John H, i used to do that a lot just touch the stomach poking out with the end of a hook making the smallest of hole, so they reckon it heals which has to be good news for the fish...

so now we have a mortality rate of say 20% or less how many snapper have we killed due to extended size limits?

not much i guess because 75%maybe never kept anything under 30cm anyway.

so roughly how many snapper are thrown back a year?
4/5million if thats the case we are still killing too many, is this ok with everyone?

considering we have trawlers killing way more the next generation is going to have to produce a lot of extras to maintain a balance...

I suspect that many people on here grossly underestimate the number of 27 - 30cm snapper kept , and the importance of them to a lot more fisherman than you think. I see thousands of these hopefuls climbing onto charter boats down here every day, all summer. Going to be sad watching many of them come home with little or no catch over the coming 6 months.

Thanks, John, for alerting us to this new research; : termed buccal venting and involved piercing the everted stomach protruding into the buccal cavity or out of the mouth with a 16-gauge hypodermic needle (a practice previously not encouraged).

I've been spouting the previous wisdom ie not encouraging.

Science never stands still, huh? (Josh W, as a qualified marine biologist, knows this; my son NJay as a qualified marine ecologist keeps reminding me...)

so now we are say nearly all these fish which are being released are motoring away will live happily ever after?
well till caught again one way or the other,

i still feel not fully convinced,
it feels like a fairy tail,
untill some more studies are done by reputable people i will endeavour to maybe feel better when someone says they let fish go from 40/60mts....

seems to me that the higher the size limit the more mortality.Lots of anglers will be returning more sub 30cm snapper in the quest for plus 30 cm fish. Some of those will not survive. A fish that is caught and handled has a chance of not surviving.

Dont think for one minute the size increase was done for you ,or the benefit of the fishery or any other reason to enhance stocks. This will increase mortality. Plain and simple.

It was a resource grab.  Take from one group and give to another. Commercial 25 cm ,recreational 30cm. Makes the concept of a shared fishery a sham.

Sometimes one sees things in a clearer way . Saw this last week. Walked into Coles in westfield  bondi junction,Sydney. And here they were . Whole N.Z snapper. Gutted and scaled,for $21.95 KG. Not one of those fish were over 30cm. All around 27-29cm. Being bought by strangers in another country, while we at home are not allowed to keep those fish
While i dont have a problem in export of fish ,this seemed wrong,in that the week before had a lean day in the gulf,and came back with hardly a feed . Returned some fish 28-29 cm. I am not allowed to keep them ,yet strangers in a another country are allowed to buy them. WHY ??

This size increase makes a mockery of MPI and a mockery of recreational. It is a bad move. Will not benefit the fishery one bit,will see some charter boats possibly go to the wall. So much for govt supporting small local business.
MPI and the govt are meant to be our servants. We pay their wages.  They obviously dont represent us or our interests in this case. Their needs to be accountability for this decision. So far there has been none. This decision,it would seem, was for the elite few & no one else .

the elite people that mouthed off about i dont take anything under 30cm is what caused the problem cirrus,
MPI saw this as a great chance to put us in a different category which was perfect for the Commercial sector,
well they got their wish and we are stuck with it...

there is no way we will ever get the Comm's to come to the party as smaller are better in there quest to supply the market,
plus until they change their way of trawling the capture of such small fish will continue, so better they make use of them than throw them back dead i guess,

how many big snapper die after release is not such a problem as they are few and far between...
