Always knew there were JP records from the Richmond River basin in NSW (from below the ol Casino Weir) but just recently a mate of mine caught these two juvenile JPs in an adjoining system in the Byron Shire - be nice to find a couple of adult ones!

No waayyyyy :GoodPost) :GoodPost) :GoodPost) :GoodPost) :GoodPost)

That sure is interesting but are they in an aquarium ? Were they collected for fisheries research or something ? Were they returned to the water of origin ? I don't want to sound critical but surely they can't be collected undersize unless with a permit or is it a case of as the fish aren't a recognised species (or are they) in NSW they don't have a state size limit. Please enlighten me. Just as an aside they apparently are found in some Sunny Coast streams as well. Cheers Pat.

can u keep a perch as pet? what sort of water would u use? river water , or rian water? or do u need a permit for native fish im not sure either?
-
RE: regs relating to Jungle Perch far as I'm aware there is no recognised bag or size limits for JPs in NSW other than the general limit of 10/day/in possession that applies non specifically to all other species other thanthe regulated ones so as long as they're taken using legal methods (in this case a dip net) there is no drama - also in Qld there is only a maximum (35cm) and no minimum size limit and a daily bag and possession limit of 1 - so therefore nbothing to stop you having one in a tank as long as its not over 35cm C:-)
-
Thanks for that info Jim. Yet again it has exposed one of the ridiculous rules of Fisheries - 10 in possession but none over 35 cm (assuming this is breeding size) if they are all taken out of a system before that size they'll never reach the no take size. And yes they would make a nice aquarium pet. Cheers Pat.
-
the general rule of 10 in possession (for non specified species) is NSW, in Qld the JP in possession /dail bag limit is 1
-
I suppose that if the JP is not listed as being present in NSW waters then you could theoretically support an unlimited possession limit. Prior to this my best advice was that they were currently unknown south of Townsville, however they were once distributed down to Brisbane. Odd that they would turn up in the Richmond system?? Any chance they may have been introduced there?

"Prior to this my best advice was that they were currently unknown south of Townsville"
What about the population in Eli Crk on Fraser Island, been there since Joseph played fullback for the Jerusalem Colts???
and they do exist in the sunshine coast, been too many reports over the years to discredit them.
Interestingly the brood female used by Dept Fisheries a few years back was caught in the Brisbane River :o

Great info JT, thanks for sharing. :youbeauty I knew they once ranged down to the Richmond River (approx), still do apparently. :youbeauty It gives me confidence that these great fish have some chance to recover on their own.
I know of a few criks in SEQ where Jungle Perch are still holding on by a thread, one of these is waaay incredible :OMG and other creeks where I was confinent of finding something turned up a big zip..... (No I won't share the locations folks).
Last one I heard of being caught in the Brisbane River was 1980, but I recon there still should be a couple holding in there, just cause we're too slack to catch them doesn't mean there arent any left about. JPs are possibly the smartest native fish I've seen, they can "wise up" very quick and are easily spooked.
-
There looks to be a fair bit of grey in that beard Jim...though its been a while since we caught up!!
-
can u get a fish like that from pet shop?
-

Maybe bootleg ones and if you pay through your teeth.
Looked into it once... not worth it and are more beautifull in the wild anyway
-

Aquarium store opposite the Rocklea Markets had one for sale when I was there once....maybe they have a supplier. :popcorn)
-
Very nice Jim an interesting find, Hutcho would be keen to get fin clips from those guys.
-
Yeah been yarning to Hutcho bout it will try to get some fish for him - Jim
-
Forgot to ask, among the many questions most interested to know how long they are ?
-
Only small mate ~10cm, my guess is they've recruited in last year, probably with marine larval drift, the couple of wet years we've been having has probably helped the SE Qld Population's recruitment prospects and a bit of larval overdrift got this far south, not sure how many have ever formed a 'resident northern NSW' population and whether they'd ever viably breed - but certainly have been previous reports of large JPs from these systems being caught by bass fishers - so maybe if they do get to a critical population size we may see some local recruitment, feel winter temperature minimums would still pull em up in most freshwater around here,.. nother couple of decades of global warming might swing it ;)

BRad, my "best advice" came from some very detailed research I did while preparing an article for a fishing magazine. There are apparently a number of JP strains, and there is always anecdotal evidence about all manner of things; especially fish. I can only surmise that the population of JP's on Fraser Island are a completely separate strain to those on the mainland.

John,
web availble information including fro state government agencies has suggested that JP were non existent south of Townsville (shoody fact checking)
http://www.daff.qld.gov.au/28_14682.htm (http://www.daff.qld.gov.au/28_14682.htm)
reality is the same agency' scientist are working with fish from Fraser Island and other refugial populations have been known to fishers for years including creeks south of Townsville(halfway to Bowen), north and south of Mackay, north of Bundaberg, Sunshine Coast and Gold Coast and the odd strays to northern NSW
http://www.daff.qld.gov.au/28_20476.htm (http://www.daff.qld.gov.au/28_20476.htm)
There is great review paper by Hutchison if I can find it (on other computer) I'll link it up for you.
If they can produce fingerlings - could probabaly kick start or mainatin populations in a number of catchments within this range
-
allrighty , got my aquirum all set up now just have to get a jungle perch,
-
Jim,
Thanks for that mate,
I know there are a number of different strains of the fish and unlike yourself have only scratched the surface. However I would have thought that as so much of our water here is a little on the turbid side that would have been a problem for the JP's as they seem to prefer very clear streams. I'd be interested in that info you've got.

John,
think attached link isthe report I was thinking about
https://docs.google.com/open?id=0B_zS6dnGFpjhMEoyLXpoa3RYemc
There are two species of jungle perch in Australia but the main one we're familiar with K.rupestris is the one that is distributed from NQ to northern NSW,it has been found to have very limited genetic differentiation probably because their marine larval stages are distributed by ocean currents and so there ends up being a fair bit of ongoing genetic flow between populations - Jim
-
Just sorted access to the document linked above for those that may have tried to access it, it is now accessible - Jim

THanks Jim, I'll print it off \John

Up the Sunshine coast yesterday, went for a quick dip net looking for some small natives. Got 2 JP's @ 35mm in a nice little creek.
-
Have you had them in tanks before? They're not very community orientated (will beat the sh!t out of everything) - but are class A1 when it comes to inteligence and character! :thumbsup
-
Did not keep them Jim, still have my pair of southerns now 50 odd cm. They are in a big system but still bicker constantly unless they are in the mood.

That would be something to see

Thats a great read thanks

This would be something to see, but a few 100K not a few dozen.

INDEED ! :GoodPost) :thanks
-
JP's are fantastic in Tanks but not overly social. As has been stated they are brutal towards just about everything else. Incredibly inteligent though. They pick up on things extremely quickly.
As for distribution I will post a pic you may find interesting.
This photo clearly shows two species of JP's and was taken in Vanauatu. Rupestris is quite widespread apparently going out to around Fiji or so but in all there are 9 different species,
-
Interesting thread. I kept a few JP and never had problems with them but had a Sooty grunter that killed everything including a mangrove jack twice his size.
